Leds on Quad, four wheeler

A little more detail on how many LEDs, what type of LEDs, specs of the LEDs would be helpful. Here's a awesome link to figure out what kind of resistors, etc. for a series/parallel LED hookup. http://led.linear1.org/led.wiz

What I wanted for someone who has done it, to show me how they did it.  If you have some info you'd like to share then by all means...share it.  I need the help.  I'd like two fixtures of 4 leds, one on the engine and one behind the seat, making a total of 8 Leds - Size 5 - 3.3v - wired in series or parallel from a 12v source.  Having a fuse and a switch.  I'd heard of wiring it to a relay, would that help?  Your respose would be so kindly welcomed.    Thank you

No problem. I've put many white LEDs on my bike. I'll see if I can post some pictures of it up this weekend to illustrate. Now for your setup. Based on your info. A string of 4 LEDs to a 13.6v source, you're going to need a 22ohm 1/4watt resistor for each string. I used 13.6v because that's close to the usual voltage when the engine is revving. As for a switch, you can get a variety of 12v rated switches at your local auto parts store. Even WalMart has them. I use two flush mount(sticky back) switches for my bike's setup. The switches are about $10 at Autozone. They have a small LED in it as well to indicate if the switch is ON(bright) or OFF(dim). These don't require me to drill a hole in the fairing. Just peel the backing off and stick it to a flat surface. Tape is 3M so it's super sticky. I've washed my bike many times and the thing is still stuck to the fairing quite nicely. It's in a dark smoke plastic. As for the fuse, I don't use one as the resistor reduces enough of the current to prevent any damage to the LEDs. If you go to the URL that I posted, all of this can be visually shown on how the LEDs and RESISTOR should be wired when you plug in your LED's specs. Source = 13.6v Diode Forward voltage = 3.3v Diode Current current = 20mA (usually standard for LEDs) Number of LEDs = 4 Hope this helped.

I'll post some pictures of what I have on my bike this weekend. http://forums.linear1.org/index.php/topic,728.0.html The above url is my latest project of converting all of the incandescent bulbs, except for dash display and headlight, to Luxeon3 LEDs. Power draw is more than the regular LEDs but still much much less than incandescents and way way brighter when the LEDs are grouped together. The first picture has part of my 5mm LEDs setup...but I'll work on getting the pictures of the entire bike with the LEDs. Oh, just in case you're wondering how those 5mm LEDs are fixed on the fairing? I found a seller on ebay that sells chrome (not that chrome color plastics) LED housings. He sold the housings along with some LEDs.
