Most LEDs don't use that much power so I'm pretty sure some sort of transistor would be required to reduce the power the LEDs get.
I calculated that for 2 LEDS for each bar I would need a 6.8 Ohm resistor for a 12V power supply. I should've used a DC regulator or something to test a live output. Didn't think it might be a different voltage just having the parking light or low beams on vs the same thing with the car actually running. Might be back to the drawing board or looking for new ideas if I decide to continue down this path. I would just rather have a solid beam than be able to see each individual LED.That's really unfortunate to hear. I'm really looking forward to seeing this up and running and installed.
All good advise above. You could also try using a DC voltage regulator, amazon sells them.
That's exactly what I think I did. Damn. Lolif you used high power cree LEDs they often need current regulation more than voltage regulation, also remember your cars electrical system is at 14v when the engine is running, 12v at rest. If you picked resistors for absolute max output at 12v you could have been overdriving them at 14v
Thanks Pauly!! I think that might be the last extra touch of blue on my car :,( unless I decide to go with a Modulo lipLove those blue reflector bowls!
It actually belongs to a good friend of mine. Just installed progress coilovers last week, rear strut bar, exhaust, wheels and carbon wrapped hood, roof and trunk. Not too sure about engine mods besides rewiring engine sensors to the ECU, but he's running a d16 that the previous owner swappedEk seems to be in decent shape too. Any mods done to that car?
