The most common issue is a light is out or the pixel count is off. Contact your local dealer to fix your lights.
If One Light Goes Out, Do They All Go Out?
The answer is sometimes. If the glitch or fault occurs within the RGB components then it will only affect that light. The light may turn a different color or shut off completely. If the glitch or fault occurs within the data wire of the affected light, it may affect all the lights after it in line.
Either way it is a quick and simple repair, reach out to your local dealer and they will swap out the affected light which will correct any issue.
