Normally I don’t care for LED’s….. But I did install some in the turn front turn, the side marker and the rear. I have had the turn signal mod for a long time. I installed led’s in the side marker no problem, but when I install them in the front that bulb will not blink when the truck is running. When just the ignition is turned on it works fine. What gives?

 

Will it light up, but not blink? Or do nothing. Does the sidemarker blink?

 

Lights up but does not blink. Works no problem (lights on or off) w/o the motor running. Side markers no problems at all. The LED's are SMT if that matters. Put a 3157 in and no problems at all.

 

I tried 194 led's in my corner lights with my blinker mod. It don't work.
