Introduction: Preventive Lights for Door Edge
This project consists in a simple lights system on the edge of the vehicle's doors that helps preventing accidents with cyclists or even other vehicles.
Many cars have a reflective or a not very noticeable courtesy light on the inner side of the door, but they're not always very effective for this purpose.
With this instructable we're trying to promote the use of these lights.
We’ll explain step by step the process to install the preventive lights for the door edge.
We used a Nissan Tsuru 2004, you have to adapt the system to your vehicle, but there's not a big difference between them.
You can check the full manual in the attached PDF.

Step 1: Get the Materials
Materials:
• 12 Volts RGB LED Set
• Cable /Wire (6m)
• Welder wire & Solder Paste
• Soldering iron.
• Scissors / Tweezers

Step 2: Cut the LED Set
The LED set comes in one piece, so then it’s necessary to cut it in a way you found the desired size. In this case we used 3 LEDs.
For these step you can use regular scissors.
*You have to pay attention on your LED set, they have specific spots were you can cut. If you cut out of these spots you'll descompose the LED set.

Step 3: Cables
In this occasion we used different wire colors to distinguish the positive alimentation and the color we will activate .We need to peel the wire tips.
Step 4: Wiring the LED Set
Weld each wire to their respective line using the soldering iron & welder wire 60/40. Also remember to respect the established colors, to avoid confusions.
Step 5: Extending the Wire
Later we'll have to weld extra wire to every tip or terminal, for this we'll only need welder wire, the soldering iron and the solder paste
In this occasion we want to create the yellow color (preventive color). Connect the negative side (ground) from the red and green wires. Join the 2 grounds to one single wire.
For the positive side we only need to weld extra wire.
The length of the extensions depends on your vehicle.

Step 6: Find and Remove the Lights Switch
You have to find the switch that activates the inside lights on each door. It’s frequently located in the door frame. Il will provide the ground for activating the LED set when you open the door.
It’s typically fixed to the frame by a screw. To remove it, you just have to unscrew it.

Step 7: Connect the Ground Line
Once you’ve removed the switch, you have to connect the ground line of the RGB LED set to it. This can be easily done by introducing the cable (previously stripped) from the back of the switch, so that it makes contact with the original cable of the switch. This way you can avoid cutting the cable.
Once inside, secure the cable to the switch using electrical tape and re-introduce the switch in its place.

Step 8: Connect the Positive Line
The next step is connectng the positive line of the RGB LED set. First, you join all the positive lines of the LED sets in one. You can connect this line to any 12V positive current source of the vehicle.
On this ocassion we’ve connected it to a fuse, but you can connect it directly to the battery or find another practical spot.

Step 9: Paste the LED Set
For pasting the LED set on the edge of the door, most of the LED sets have an adhesive, but if they don’t have, you can use any industrial glue.
Step 10: Hide the Wires
Once you’ve pasted the LED set you have to adapt the cables to the vehicle so they don’t hinder the driving.
You can use electrical tape for fixing the cable or any other method if you want.
On the door, the cables can be easily hidden inside the gasket.
You have to leave extra cable on the joint of the door and the vehicle so the cable doesn’t break when you open the door.

Step 11: C'est Fini
On these images, we can appreciate the preventive door edge lights working, we can observe how they excel in the dark, warning the presence of a hazard.
