Ok guys here is my dilemma. I have a 1973 IH truck, the tail lights suck basically and I know just using a plug and play 1157 led bulb will too.
I would like to construct two circuit boards using red 5mm led's for the brake/tail lights and white for the reverse lights.
My question: obviously I have to use a regulator which I've already learned from searching the site, but what is the best way to build these so that the lights are on with the running lights and when the brakes are applied they become 2-3 times brighter?
Dual fillament LEDs or what? I am new to this game and would appreciate any help, advice or anything to get me rolling on this project.
