Parking brake Light illuminates, goes out, dash power flashes off, then on

hello,
curious if any of you have seen this issue or know where I need to start and what to look for. Randomly, my 05 f350 lariat 4wd 6.0 parking brake light will illuminate then go off along with the rest of the power all along the dash. It will turn off about three to five seconds then power back on. It has an aftermarket radio, not sure if this would have anything to do with the issues. Just had the rear brakes replaced as well, but issue occurred before and after that maint. Any help would be appreciated.

Sometimes if we suspect a problem is coming from an after market add on, we will disconnect it from the vehicle and see what result we get. You might consider starting there.
