Our scare light didn't work either, while doing our PDI, the rep, just flipped the switch & I assumed it worked. After I got home & found that it didn't, I 1st checked the fuses, & found them to all be ok. I then checked the bulb & checked it for continuity & it too was fine. I then pulled the switch out, & found that the power wire, had come off the back of the switch, problem fixed.
