If you are having issues with the LED’s, it is usually something simple to make them work properly.

Check the list below to see if one of these will cure your problems.
(if not, contact us)


If the LED is not lighting up, check the orientation. Flip the bulb 180 degrees, put it back in the socket, and see if that helps.


If the lights do not blink, it could be several things, check all of these:

Make sure the front side corner light has been cut and ground, per the directions.

Make sure the flasher units are grounded properly.

On some G-body cars, the led flasher polarity may need to be reversed.
(use the enclosed 2 wires & criss cross the leads per the directions)

Backup light bulbs: if they don’t fit into the socket all the way, you may have to trim down the lower base (the outer ring on the bulb that fits into the socket, that is probably what is preventing it from seating properly).
ONLY trim it enough to fit inside socket! This ring is part of what holds the entire bulb together so don’t trim too much!
you can switch out these reverse lights for ANY of the following bulbs in the kit, as they use the same socket:
Underhood, trunk, third brake light, passenger under dash.
The backup lights are slightly brighter than these other bulbs, but the they will work and fit fine.

Regal LIMITED: front lower cornering lights:
You MAY have to cut the black wire and ground this wire IF these lights start blinking with the turn signals on.
On both sides of the car, attach a new ground wire to the bulb side, tape off other cut end.
Check them with your headlights ON.
