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
• 12 Volts RGB LED Set
• Cable /Wire (6m)
• Welder wire & Solder Paste
• Soldering iron.
• Scissors / Tweezers
Step 2: Cut the LED Set
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
Step 4: Wiring the LED Set
Step 5: Extending the Wire
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
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 inside, secure the cable to the switch using electrical tape and re-introduce the switch in its place.
Step 8: Connect the Positive Line
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
Step 10: Hide the Wires
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.
