LEDs..how to go from 12v to 6v, I got 2 6volt leds and I need to tap them onto 12v power Options

[Black0nBlack94]

Any body have any idea how or what I should use to make a 6volt LED light on a 12volt power supply? I know that if I tap it on directly to the 12volt it will burn but I cant figure out how to make it light without burning. I want to install 2 blue LEDs, one on each door behind the lock and I plan to take power from the courtesy light. But After the current leaves the courtesy light and before it reaches the LED...I need to lower the current. I think I need a resisitor but I dont know specificly which one. If anyone has done this before let me know what I need to do. Thanks 6gcers

cool project.

you'll need the led current too. but this will tell you.

to get a big enough resistors you might need to go with these guys

that being said, you can always get led + resistor fabrications at autolumination.com and just solder their legs to your wires. might even be able to find sockets for them so you can have a replaceable bulb.
