Before I ask, I'm sure this has been beat up but I cannot find my answer after much searching. I have a 2004.5 500HO with a 1157 taillight lamp. I'm trying to save some power for accessories by changing it to LED. I tried a simple replacement 1157 LED lamp but it isn't working. Do I need a resistor or does Polaris have some funky wiring? The harness is unmolested and it was even the original lamp. I bought the machine new. Thanks for any help!
