LED bulbs that don’t suck 2015 Sierra SLT

2015 High Miler · January 11, 2021

It’s probably been asked but I am not finding anything on a search. Looking for bulbs for my 15 Sierra SLT. Bought some Amazon specials and they are already blinking after y months or so. Would like something simple to replace in the stock housing, nothing crazy but durable if possible.

Please point me in the right direction. Thanks

I have Diode Dynamics SL1 LEDs in my 15 All Terrain SLT. Been happy with them! Much better than stock.

Thank you for the video link !

I like that dynamic diode is American made.

This gives me a little better picture of what I need to look at.

Thanks again!

Last year, I reached out to HR with every intention of purchasing their GTR Ultra 2 bulbs, but they recommended the S-V4 for my rig -- Sierra SLE with projector headlights -- I'm happy with them and they fit entirely inside the headlight housing (no holes in the dust covers!).
