Perhaps the best thing about LEDs is how easy it is for just about anyone with a little knowledge of electrical circuitry to create their own simple lighting solutions for just about any purpose you can think of. For instance, if you’ve always wanted lights that light up your car doors every time they open, you may want to check this instructable below.
New cars sometimes come with lights built into the doors — a safety feature that warns other motorists and cyclists of the hazard your car’s open door presents. If you want to try putting them in your car too, Instructables user Carlos shows us how to install them.
You’ll need a 12V RGB LED light set, four electrical wires, a soldering iron, welder wire and soldering paste. Connect the wires to each of the four lines on the light set with the soldering iron and welder wire, and then connect that to the existing wiring in your car’s door.
