Okay I saw another post on here but the resolve never came back. My turn signals do not work with the new upgraded LED and flashers. But my hazards do work. I have replaced the flashers with the low voltage flashers made for LEDs. This isn't the first time I've done this on an older vehicle but this is the weirdest problem. I have checked to make sure that the bulbs are in correctly. It doesn't blink left or right. But the flashers do work

Need to cut one of the wires for the front turn signals, and run a ground. Search around for the kits to convert to led lights and one of them explains it all

I kept my 1157’s and 1156’s stock. Brand new old school stock bulbs. I didnt trust the led for this must -work brake/turn /park light scenario. All the other lights LED

may require the LED flasher. regular flasher relay is not sensitive enough to the tiny voltage drop caused by LED. any solid light such as brake/headlight should be good as LED

I put in two LED flashers in my boy's car after changing all the bulbs to LED. Everything works like it did with the OE flashers & regular bulbs.

yes that does sound weird the turn sig and 4 way flashers have 2 different flashers so they are different i think you have to have the key on to make the turn sig work that changes things so check the grounds to all 4 bulbs bad grounds do all kinds of weird stuff
