Thread: official switchback/led bulb hyperflash fix and sidemarker flash delete.

Another interesting twist.....

I just swapped in the EP28 flasher and some Putco LED bulbs (non switchback). All was good until this morning, when I noticed that when the park lights are on, the signal indicators on the dash are lit up dimmly. Other than that, everything is just fine.

I'm guessing that something is back feeding? Bad bulb?

FYI.....

I put a diode on each signal wire (dark blue wire) at the front light sockets and that fixed the problem.
