Hey guys, i wanna put some Leds in the car for some effects. Yeah yeah say whatever you want. But anyway i was wondering about power supply. I was thinking of running a thin power cable from the battery to a little distribution block located somewhere. Then from this distribution block i would run the leds off it to the desired location. Anyway i was wondering would i need a resistor for each LED or could i just have one 560ohm resistor before the power get to the distribution block(home made of course).

Cheers fellas

the resistance of the resister would depened on how many leds u have so it mightant be a 560ohm resister. but imo best way to do it would do a resister on each one because that way u can always add more leds and stuff like that.

i think it would look really good if done right. what type of look are u goign for? like a spot light or a glow type of thigs.

sorry i was thinking of wireing it in series yeh just do one resister in the block and wire them up in parael

If your LEDS will be inside, you could run your power off the interior fusebox - typical LEDS only draw around 120 milliwatts.

You can get away with the one, but you need to increase it's power rating, and this will be dependant on the number of LEDs.

By my calculations, you should be able to put 2 LED's in parallel, and then in series with 1 560 ohm ¼watt resistor. If you need 4 LEDs in a row, you can put them in series with each other, without a resistor - each drops 3.4 v, so 4 x 3.4 = 13.6v, I've tested this, and works fine. You can also run 3 LEDs in series without a resistor on 12v, I've tested this also, but the life of the LEDs may be shortened by the larger operating voltage across each LED. So you do have a few options . . . .

For those with a little electrical knowledge - here's a handy webpage to calculate components and ratings for different LED configurations: http://www.besthongkong.com/clrc.htm

cheap and easy too. they are easy to hide with minimal visibility but heaps of light output. i replaced the light above the ignision switch with a LED also. even put a few on my motorbike while i was at it.
