dome light triggered led footwell lighting for a 2010 ...
This manual introduces red in detail-green-blue (RGB)
LED Foot light with Honda Fit 2010.
For this type of application, rgb led kits and controllers can be purchased at any time on websites such as Amazon. com.
I chose not to use the business suite for two reasons.
First of all, it\'s nothing fun.
Second, most of the kits either lack functionality or have features that I want to avoid, such as the remote control.
For my design, I blade want the following features: the last point is the most challenging requirement.
During installation, the dome light lights up for various activities such as opening the door or pulling out the key from the ignition.
It will turn off automatically and it will slowly disappear when it turns off.
This fading effect may be generated by attenuation of the current through the dome bulb.
This project requires the LED controller to have a separate power supply than the LED itself.
That said, you can\'t connect the controller to the Dome lighting circuit because the dimming controller is not advisable.
Also, I want the LED and the controller to be on a fuse different from the dome light.
The uniqueness of this note is that the rgb led controller is rewired to separate the three circuits (
Top light, controller and LED)
But they are allowed to act in unison.
Of course, you need this car first.
Only 2010 Honda fit is considered for this instructable, but should apply to any number of cars and trucks.
Basic welding skills are required.
The main components of this project are: the rgb led dimmer/controller should have analog control (
Potentiometer knob)
One for each channel.
It is also important that the public output matches the polarity of the LED strip common rail.
The controller used here has a separate ground for each RGB channel and outputs a common 12 V.
The LED strips are also \"co-anode\", which means they have a 12v connection and three ground connections, one for each RGB channel.
The LED strips I can find are all 5 m long, which is much more needed than this project.
However, the cost is not serious.
I paid $13 for shipping.
I would recommend looking for a 5050 LED belt as these are brighter than 3528.
Another big difference is that on one of the 5050, each chip has three LEDs, one red, green and blue.
On one of the 3528, each chip is either red or green or blue.
Colors from 5050 bars will be better mixed as the spacing of the component LED is closer.
Also make sure the supplier has sent you the correct parts.
The real LED chip of RGB 5050 LED should be white.
If it is yellow, the supplier has sent you a white LED-
You will not be able to change the color.
You can choose to be waterproof or notwaterproof.
I used a non here.
Waterproof strips, but waterproof may be a better option and should be equally effective. The add-a-fuse (fuse tap)
It should be ATM or \"mini\" size.
The Honda Fit 2010 features a low-key mini fuse.
It\'s hard to find a low profile fuse plug, but ATM (mini)
Fuse tap will fit.
We will tap an unused socket in Fit\'s fuse box, so we only need an ATM (mini)
The fuse of our new circuit
If you are modifying a different vehicle, be sure to install the fuse tap in the fuse panel and the corresponding fuse. We need 4-
Wire and Cable from LED light strip to dimmer/controller.
We will also reconnect the RGB dimmer/controller with some of these wires etc.
We need to connect the new wires to the dimmer/control box.
We want the wire to be easily disconnected, so you need some sort of wire terminal or plug along with the corresponding terminal or Jack.
I used a connector that was removed from the old board.
To access the round dome lamp circuit, t-tap is handy.
This will bite into the ground wire of the Dome lighting circuit without requiring you to cut off the wires. These t-
The tap connector accepts wire terminals of the blade type, so you need at least one of them.
To connect the LED light strip to the underside of the interior of the vehicle, I chose the tape.
This tape usually has a sticky backing of 3m but I find it lacks adhesive strength.
Many people choose to drill holes and use wire ties.
I need to avoid changing the decor in any fuse way, so it\'s electrical tape.
RGB dimmer/controller used in this project use pulse-
Width Modulation to control the strength of the LED.
Since the LED cannot be darkened by lowering the supply voltage, it is necessary to maintain the supply voltage (here 12 V)
, Pulse power supply, and use pulse intervals to control the observed strength.
The potentiometer on the dimmer controls the pulse width or the time applied by each pulse.
To turn on/off the LED circuit during/after the pulse, use the MOSFET.
The MOSFET has three terminals: Gate, source and drain.
For the MOSFET type found in this controller, when the voltage fuse is applied between the gates (+)and source (-)
Current flow between drain (+)and source (-).
The controller logic applies voltage to the gate and source to turn on the LED.
In the initial configuration, the controller logic and the LED share the 12v power supply and ground.
In our design, the LED will share a piece of land with the dome light.
The controller logic cannot share the ground of the dome light because the fuzzy/faded logic circuit is undesirable.
Imagine dimming the power supply of the computer.
The result is not good and may damage the digital part.
In order to decoupling the LED circuit, we will unlock the source pins of the MOSFET and connect them to the new ground input connector.
Later, we will connect the ground wire of the dome lamp on this connector.
In the photo, you can see that I undid each source pin and attached a small wire to each pin.
All three wires are welded to my hot connector
Stick together through a hole on the controller housing.
In another photo you can see the gray short wire attached to this new ground pin.
When the wire is connected in turn to the ground input of the controller logic circuit, the dimmer/controller is restored to its original design/operation.
When the project is completed, this is not where this line will be connected, but a good way to test that you have not broken the dimmer/controller.
When operating in this way, the entire 5 m strip is connected, the level of each channel reaches the maximum, and my strip is pulled less than 1a
To power our controller, we will tap the 12v socket that is not used in the fuse box.
The empty socket is 4.
Even if the car is off and the key is not in the ignition, it should have a constant 12v power supply.
The dome lamp circuit has the same type of power supply.
This way, when you open the door for the first time, the light will light up before you get on the bus and turn on the car.
We could have lit the ceiling light with a 12 V line. This will work.
Some of you may have chosen to do so since then, and you do not need to buy fuses and fuses.
I want my LED to be on a different fuse/circuit from the dome light.
It\'s easy to tap the socket.
First, put the new fuse in the top slot of the fuse tap.
There should be a curl connector at the end of the fuse tap line.
Press a short wire to extend its length.
Then push the fuse tap into the empty socket.
The suspended wire will be connected to the 12v input of the controller, which is one of the green screw terminals on the left.
The controller needs its own grounding.
To do this, it is simple enough to connect the wire to the ground input of the controller (
Green screw terminal on left side)
And run it on the chassis of the car.
I found a screw nearby and I connected the ground wire there.
Finally, we need to connect the ground wire of the dome lamp to the ground terminal of the LED, which is the wire we added to the controller housing.
We will use t-here-tap.
The dome light line can be found at the bottom of the fuse panel.
In a small green connector, two wires, one pink and one cyan should be the only two wires.
Unplug the connector for easier access. Clamp the t-
Tap the connector somewhere on the cyan wire.
Curl the blade connector to one end of the short wire.
At the other end, the plug or Terminator paired with the jack or connector you installed on the controller housing will be connected. Then plug-
Make this connection in the wire.
After completing this step, you should see that the red power indicator LED of the controller is always on.
The controller is always on, but the LED will only turn on if the top light ground connection switch is off.
This action is controlled by the micro-controller of the car and triggered by several events such as opening the door or removing the key from the ignition.
I have already measured this controller circuit always-
On state takes about 17 mA out of the battery.
Given that the car battery can supply more than 10,000, this circuit will not run out of the battery for any actual time.
You need to choose where to install the LED light strip.
I had a strap on both sides, the driver and the passenger.
I stick them under the car decoration, where the black plastic is almost flat on the width of the foot board.
After selecting the position, measure how long the strip will take, and then cut the appropriate size strip from the 5 m rgb led line axis.
The one I use can be cut every 3 pieces, so every 2 inch pieces.
When you cut the strip, you cut in the middle of the bare copper connector located between each segment.
My two straps are 14 inch and 16 inch long.
From spare 4-
Wire and Cable cut one length for each of the two LED light strips.
The strap on the driver\'s side requires a much shorter cable than the passenger side.
To measure, run the cable along the planned route to the LED light strip.
It\'s a good idea to spend more length.
I used 24 inch. 4-
Wire and cable connected to the driver side LED light strip and 48 inch pieces connected to the passenger side light strip.
You will want to weld the RGB cable to the strip before trying to cross the car.
The cable behind the trim and panel is then fed all the way into the fuse box cavity where the controller/dimmer will reside.
Next, it is a good idea to clean the plastic, where you will stick to the LED light strip with a little soap, water or alcohol to remove any dirt or oil.
Then take out the plastic backing of the LED strip, expose the adhesive and press it in place.
You will need to protect them using the installation method of your choice.
I chose to attach the LED light strip firmly to the plastic with tape.
If you choose to use the tape as well, make sure it\'s a high quality tapestuck.
Now run all the necessary cables and wires and you can connect all the cables and wires to the proper terminals of the dimmer/controller.
This will be installed in turn on the lower side of the leftmost cup holder on the driver\'s side.
If you reach the fuse box cavity at the top, you should be able to feel the underside of the cup holder.
This provides a plane that can paste the dimmer/controller.
Cut a piece of Velcro (
Hook or loop, it\'s okay)
And stick it on the lower side of the cup holder.
Stick another part of the same length but opposite the closed type to the back of the dimmer/controller housing.
It should always be placed on the left side of the house.
Install the dimmer/controller now (upside-down)
Just press the two velcro surfaces together.
The rgb led should work at this point.
They should appear when the door is open, and when the door is closed, they disappear with the dome light.
The round top light for Fit has three settings, closing, doors and opening.
In the ON position, the dome lamp is kept in constant lighting.
Since the ground connection used by this setting is different from the door setting, the LED light bar installed on this location does not light up.
When the top light switch is in the on position, in order for the light strip to open, a small diode is connected to the top light between the door and the negative terminal of the lamp.
It is necessary to use a diode so that the current cannot flow from the lamp to the door through this additional connection, otherwise the dome lamp will work in door mode even if it is turned off.
The diode only allows one-way flow of current.
Therefore, it must be directed in the right direction when installing.
In order to enter the ceiling light, pry open the transparent plastic cover with a knife or screwdriver first.
Then, by removing the two screws and unplugging the wire connector, the entire housing can be removed from the ceiling.
In the photo, you can see the connection position of the diode.
Unfortunately, it is not possible to weld to metal contacts with a normal solder paste.
I happen to have some conductive silver epoxy on hand to connect the diode leads.
Pay attention to the direction of the diode.
The white line runs on the right side of the circumference diode.
Be sure to select the appropriate size diode.
I grabbed this from another old circuit board.
Its rated voltage is 20 A and 50 v, which is much higher than what we require here.
After connecting the diode, simply reinstall the dome lamp housing to the ceiling of the car.
Completed the project.
Once everything is connected, you should find that the LED matches the operation of the dome lamp.
They appear when the doors are open, and they disappear when the doors are closed.
The LED also lights up when the top light switches to the always on position.
Note: As mentioned earlier, the LED function cannot be turned off.
Even if the dome light switches to the off position, the LED will work with the door.
In order to cooperate with the closing operation of the dome lamp, it is necessary to cut off the wires that I do not want to do.
The LED dimmer/controller can connect a separate on/off switch, but you need a convenient switch position.
Without drilling holes or cutting holes in the decoration, I can\'t see where the switch is installed.
In order to set the color of the LED strip, it is necessary to open the fuse box cavity to access the knob of the dimmer/controller.
I hope I have no reason to change colors often once set to beautiful colors,

It should be ATM or \"mini\" size.

It\'s hard to find a low profile fuse plug, but ATM (mini)
Fuse tap will fit.
We will tap an unused socket in Fit\'s fuse box, so we only need an ATM (mini)
