So I keep running into this same problem with every LED 194 I buy. So here it is..... I've tried a few different brands of LED's and they always end up flickering after a few days. Same results in my corner lenses and now in my dash gauges. My tail lights I don't have a problem. Do I need to do something with my wiring? I'm no electrician but I can do some wiring.

 

I had a problem with one of my corner lights, it flickered. I Weapped electrical tape around th base and it worked. It was a little loose. Mayb that can be your problem?

 

Well I've never had a problem with the normal incandescent bulbs, they worked fine. Cuz I'm getting the same problem in my gauge cluster and there's really nothing you can do to make them a tighter fit. Could it be inconsistent voltage? I have no I idea.

 

Had a 94 truck not to long ago in our shop. Same problem, but a little different. It ended up being the turn signal/headlight switch. I didnt believe out tech who has been here for 25+ years, he said he lost count, but he proved me wrong.
We could hold the switch half way between the running lights and headlights and they would stay on. Or if we needed turn signals we also had to first turn on the signals then hold it anywhere between runninglights/headlights/or off. Kind of hard to explain.

 

It only happens with LED's in my corner lights and now my gauge cluster. I put 360° LED's in my gauges and now they too are flickering. Guess I'll have to go back to normal bulbs
