i installed some LED license plate lights and wired them into the exsisting license plate wiring in the tail. now whenever i turn the bike on, the 5A fuse keeps blowing. do i need a resistor of some kind? the package said easy installation but its not turning out to be as easy as i thought. i checked the wiring and i don't see any problems where it might be touching the frame that would cause it to short out.

any suggestions?

:-\

LEDs use less output than incandescent bulbs.

If you are blowing fuses, you have shorted a connection somewhere.

Without a newer style flasher relay that works with LED or incandescent bulbs, you will need a resistor to reduce flasher speed.

+1 on all the above. Check to make sure you haven't pinched a wire somewhere in the routing of the new harness, etc.

well this just sucks. all it's going to be doing is outputting light on the license plate at all times. i won't need a relay of any kind.

i will look over it again. gotta go back to pep boys to buy another 5-pack of fuses.

thx.

i took the LED's to my godfathers house and we ended up with the conclusion that one of the LED bolt's was not working properly. we ran some tests on it with the volt meter (i don't know anything about volt meters) and he was able to make one of them light up with no problem. the other one was dead. he said this was why it kept blowing the fuse. we went back out to the bike and hooked up the good one. it worked fine. i took them back to the cycle shop and now i have to wait for another set because they are on backorder.

so these are the bolt leds?

If an LED behaves like a regular diode it may have gone through breakdown, similar to a zener or avalanch diode. Some breakdowns can be as high as 10Volts. Basically you or someone at the factory may have accidentally tested the LED in reverse bias mode (reversing the polarity), caused it to breakdown, destroyed/fused the junction, and caused a short in the LED itself....Theoretically...
