I made a panel of LEDs to go behind my stock lenses on my car, but I'm not sure which wiring configuration I want to use. On the first set of pics, the brightness is varied by just the number of LEDs on at a time. On the second set, the brightness is what varies, not the amount of them turned on. well here are my choices... This is of the regular tail lights. This is of just the brake lights. This is the tail lights with the brake lights. OR Tail lights Brake lights In a way I think the first set is cooler since they show off the fact that they're LEDs, but then the second is cool too. I can't decide. Edited to show original pics. Here are a couple of the finished product too. The second pic is of the brake lights on. The exposure changed though, that's why they look orange.
