where do i get an orange orange brown resistor for the halo's? i need the same resistor color as in the "changing the color of your halo headlights" write up... orange orange brown... a 330ohm 1/2watt 20% resistor that i cannot find anywhere..... my question is where the hell do i get these resistors from?.. anybody have a clue??? ive tried ebay, google, and bing and come up short.. all i can find is the orange orange brown gold which is a 5% resistor and i need a 20%.. please help!

Why would you need 20%? That forth band just gives the tolerance of the resistor. A gold fourth band means that the actual resistance is within +/-5% of the stated resistance while no band is +/-20%.

well i did that www.led.linear1.org/led.wiz and i bought some red led's, put in the info and it told me a 330 1/2w orange orange brown resistor and i looked on the site and an orange orange brown resistor is a 20%, an orange orange brown gold resistor is a 5%.. aaaand i cannot find an orange orange brown resistor anywhere!

For something like LEDs, the first 3 bands are what are important (orange orange brown in this case). The fourth band is the tolerance. 5% tolerance is better than 20% as you won't have near as much variance in the actual value vs its rating.
The vast majority of resistors out there have the fourth band on them, either silver (10%) or gold (5%). 20% are hard to come by because manufacturing them is good enough to not have that much variance. That much variance is bad anyway.

SparkyJJO thanks for the simplification.... i consider myself a little electrical savvy but these resistors were confusing me.. i was thinking the opposite way with the 5-20% being 20% a better tolerance... thanks again man

well i got the red led's in the halo headlights and used the orange orange brown gold resistors (330ohm 1/2watt 5% tolerance) and they work like they should... if anybody needs this info
