I installed Grote 44891’s LED Flashers and I only get one flash per side then nothing after that, I got LED’s in all 4 corners plus the side marker lights up front, whatever side I add a incandescent bulb to in the turn signal socket, it works perfectly normal along with the side marker light…..what can be my problem?? Thanks

 

Try a different flasher or else add a 10 ohm resister in parallel to the led's on each side.

 

to each led as in just the turn signals up front or the front side markers too? Thanks

 

Should be sufficient to just add them to the rear brake circuit on each side unless the turn signal has a separate bulb.
