Expert Reply:
You'll need to test to see if there is power getting to the LED light, and for that you'd test the red power wire using Cordless Circuit Tester # PTW2979.
Removing it from the dash just depends on how you got it in, but generally it is drilled into the dash, with the decal pressed over the hole, so you'd need to remove that to access it. If the light is not working you'd need to replace it with RoadMaster Replacement LED Display Monitor for BrakeMaster Systems # RM-300065-00.
