2014 Sierra/Silverado Bulb Sizes

[jonboy77]

Alright guys. I am ticked and need some help. I replaced my back up lights (all of them) with 921 LEDs. They weren't cheap. $20 a pair. I ordered 6 more to replace the brake lights and blinker lights. I did not realize that a 921 and a 921 LL was different. Is this right. At the beginning of this thread says GMC 921LL are turn signals and brakes. I guess my question is, is there a difference between these 2 or did I order the wrong bulb

any ideas? Should I not replace the turn signals or brake light with leds

Yes theyre different or they would be just 921. Imo you dont need to replace the brake light or turn signal. The LED reverse light though brighter for other drivers to see u in reverse along with providing extra light but you dont need "more" light when breaking or turning.

 

 

Id just return the 921LL bulb especially since u paid that much. My 921 were like $20 for 2

I thought the "LL" after bulbs meant Long Life! Use them in the Harley and yes they are more expensive.

Just installed the bulbs that No Tyme recommended. I'm pleased with them. I don't know how any one gets LEDs in the Silverado. That space behind the dust caps is SMALL!

Do you have a pic of the front of the truck to show the color of the lights?

so those of you with LED high beams .. what are you using?

 

Each time I look up high beams I get 9005 which is correct but majority are describing them as DRLs, fog lights ... NOT high beams. And the reviews are more complaining not bright enough for a high beam.

Got LED fogs in tonight. Match up nice with my headlights
