Hello!

I want to do my headlights like this:

The thread owner hasn't been active for awhile so I'm not bothering asking him. In his project he used individual LEDs with their own wires. My question is how do I wire these individual LEDs, i.e., seriers or parallel circuit or other? And if I want the LEDs to turn on and off with the car, where is the best way to wire them to?

Thanks!

 

baking headlight in the oven...

priceless!

 

As far as series or parallel it all depends on the LEDs you're using and what resistors. You can go to LED series parallel array wizard to calculate what resistors you need. This will also have different wiring diagrams based on how many LEDs you want to use. It may break them up into sets of 2, 3, or whatever depending on the specs unless the leds you get are set for 12v to 15v with built in resistors anyway in which case, they all connect directly to 12v + and - and your only consideration is how many you put per fuse/relay. I would recommend using a relay and appropriate fuses. It's just the proper way to do it.

EDIT: The LEDs stated in the thread are 9v to 15v and no need for resistors. So you would connect as many of them in parallel that would be safe for the fuse/relay supplying them. He's using 13 per side @ 200mA each would be just about 2.5 amps per side or 5 amps total. I would run all 26 on a relay and a 7.5 amp fuse. Basically: Switch to coil on relay. Fuse to load on relay, to POS on all LEDs. NEG for all LEDs to ground.

 

You do realize that any headlight customisation requires either baking headlights in the oven or using a heat gun to open them up right?

 

heat gun yes, oven..no, but hey in the end, whatever gets the job done right?

 

Thank you! This is the answer I'm looking for!
