Led upgrade problem

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?

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.
