I recently removed my bed to install a flatbed. I had my bed off and nothing what so ever on the back of my truck for a while. Now that I got my bed on and I wired up the lights (LED's if that matters) the turn signals flash extremely fast. All 4 corners work with the blinkers on. The only thing I can think of is that the LED's draw so little they still think the bulb is blown. Any ideas on how to fix this?
