My truck has gremlins (in the dash)

[Swar]

Something strange is going on...
I noticed while driving the other day the dash lights blink when I flip the turn signals on.
A couple important things to know,
This started after I installed electronic flashers for the turn signals and hazards.
Only the aftermarket gauges are blinking. Not the stock speedo and fuel gauge.
They don't blink when the lights are on.

Does anyone have experience with the electronic flashers? I think they are causing it somehow...
I installed them so I could use LED bulbs.
