My 1/24th Cabover long project

[dabears]

Yea they are 3v 1mm leds.. Problem is when I ordered 200 more of different kind they came in 3 different voltages. That's my main hang up is the lights. The truck can be done in 2 days easy but until I figure out wiring I'm stuck where I'm at and pulling my hair out. Was thinking of going the add on relay board from as-tronics as thru say it can handle 200 3v leds... So idk. I need help figuring it out or I have to do it with fiber optics and that's easier said then done as well. I'm about ready to scratch the light idea just to finish the truck
