Eyebrow LEDs not working
Hey guys,
I am trying to install my AZN optics leds for the eyebrows but am having trouble. I have followed the diy but only one led is lighting up on each eye brow (outermost driver side led and innermost passenger side led.)
When I removed the stock bulbs they were lighting up fine but now when I put the stock bulbs back in after testing the LEDs, the stock bulbs wont light either.
I've checked the fuses and they all seem OK. I'm very frustrated - any help would be appreciated. Thanks!

were you aware of the polarity of the led bulbs?
are your stock bulbs good?
are the metal fins inside the sockets having good contacts with the conductors?
calm down first, i don't think you are having a big trouble here.

+1 If the first time you insert it the incorrect way the CAN-BUS sensor will detect an error on the bulb/wire and turn off the power to that bulb. You need to flip the LED around, restart the car, and turn on the lights.
