Led upgrade problem

[bsabins]

I recently installed hikari led headlights in my 2015 denali hd. Lights work until truck is turned on and then shut off after about 3 seconds. Any ideas?

is your headlight switch on AUTO or turn on all the way ??

[bsabins]

I've tried both ways. Same end result

My truck was made in 14. I read a service bulletin stating trucks made in my body style prior to 15 had a headlight calibration in the bcm with a lower watt threshold

BCM headlight calibration was a 1500 issue only.

 

I'd be suspect of the bulbs you bought being the issue (hong kong amazon specials).  

 

I've only used VLED in the past.  Sure they are more $$$ but they've never given me an issue.  Their Micro Evolution line fits inside headlights just like a factory bulb would and even with all the wiring tucked into the lamps, I've never had one fail yet.

Oh ok. You are right. Should have known better. They had great reviews. Smh
