Hi Tom,

The parts I used are similar to those listed below. The cost per car was about $6, far less than buying a complete module kit that you would still have to install with almost the same amount of work.

Not complicated at all, I am very novice in electronics and have done a ton of cars with the LED strips . A rectifier followed by a capacitor, then an inexpensive regulator to the LED strip. Cost will be under$3.00 per car.

Wow, that’s a lot of information. What I am not clear on are the specifics. I run DC so I understand I have no need for the rectifier, but from there, a capacitor (what value?), a regulator (again, what value), and a Buck Booster (is the one in the eBay link the one I should use or just similar?).  Then there's the resistor's for each LED.  When I try to put together the 3 threads, I get lost.

Am I missing something?
