I pulled all 13 of the LED bulbs and put the stock ones back in. Left the electonic flasher unit in since it is more trouble to replace. Everything works as it is supposed to. I put the LED side marker and top brake LED back in and everything still works ok. Don't have time today but I am going to put the LED lights back in one at a time until the problem re- appears.

If theres a range specified for this device, check to make sure it is within the specified load. Since filament lights normally draw a much larger current for the normal switch/flasher unit to operate properly it makes sense that a solid state flasher unit works for the much lower load current draws of the LED lights. Perhaps there is a tolerance of current which the device is unable to handle outside of the current draw it is designed for. |
