Hey all!!

Bought some dope LEd tail lights from TM tuning and waited all but a month
to get them Should be a plug and play assembly but they wont power up
at all

Any ideas of what may be the issue???

This might be related to a lack or resistance. I put LEDs inside (dome lights and whatnot) and they didn't work until I hard-wired my radar detector to the dome light's power. An electrical engineer told me that he thinks the circuit doesnt have enough resistance and I'd have to add the right amount of resistance to get them working without the radar detector which sucks.
