Where would I check for ground wire since I just removed the one bulb and plugged in the switch back Led bulb? I have led headlight bulbs and no flicker so it all of the same harness it seems. Only when I swapped out these bulbs... Only the front turn signal switch back flicker when everything is on..

It is NOT the bulbs. You've been given good advice on looking for a ground problem. Another problem area could be a bleeding diode in the alternator causing a ripple current (AC) riding on the DC (direct current).

Thanks also... Only reason I wasn't fixed on the ground is because why only the signals leds flicker and not the headlight bulbs.. Its all on the same harness, I was outside looking over it... My truck just clicked 4k miles yesterday so it's new still even though it's a 17...so Ill look more into it...

Are you referring to the turn signal lights? Both front and rear, both sides flicker? No other lights, inside or out, flicker? You're under warranty. Take the problem to the dealer.

I had the same problem. Halogens were fine, switched to cheap LEDs, they flickered intermittently. Switched to name brand LEDs and the problem went away.

Question—does the whole bulb flicker or do some of the many LED chips flicker? What I’ve seen with cheap bulbs is some of the LED chips flicker while others stay lit. I really doubt there is a ground problem or something wrong with your alternator. You changed the bulbs. That’s the best place to start looking. Do you have your old bulbs to switch back in and try?

Yeah I changed them back to the stock ones...
There are a cheaper brand . Came with the resistors too... The whole bulb flickers... I say cheaper cause I didn't get them off a name brand site... They look nice though... Amazon . Maybe it's the bulbs then... Just was odd I plugged them in and it did the flickering deal... Risistors are good cause I got no error message on the dash so I would just need new bulbs?

I agree... My truck didn't come with the factory led headlight assembly I have the standard 2 bulb per side halogens. I switched out the front turn signals for led switch back type leds.. Switch back meaning they are white until you hit the turn signal then they light up amber... I also have sets of beamtech hi and low beam leds..

I used Alla LED bulbs for both switchback and for my fog lights. The switchbacks have been in since the beginning of the year with no problems. I had one fog light burn out after several months. Contacted Alla via Amazon and they replaced it right away with no problem. I simply returned the bad bulb to them.
