Fit for 2008-2013 GMC Sierra 1500 LED Bulbs H11 9005 Exterior Interior Lights Plug and Play

Absolutely love these lights, had an issue and lasfit team corrected and was so helpful and speedy. Will definitely be purchasing lights from Lasfit from now on!

These bulbs are great so far and there was a shipping issue that Lasfit corrected right away sending out a replacement set. I'll definitely be buying from them in the future.

lights are super bright and great quality. the customer service is unmatched. never have I been treated better by another company multiple times without any problems what so ever. this is my 3rd vehicle getting las fit LEDS on them and I can’t get enough!

**see update below**
Replaced all the lights on my front end last night. The low beam/high beam/switchback fog lights look amazing. The yellow LED side markers look great. I really love how the switchback turn signals look, white as running lights to bright yellow on the turn signal. I had LED headlights before, but they were dim. I am absolutely in love with my low beam power and clarity now.

Only issue I have is that the turn signals are hyper-flashing. I was dumb and only bought 2 (the truck needs 4 turn signal bulbs), I decided to put the two in and see if I liked it or if it looked odd and get another 2 to complete it. I thought that leaving the bottom two bulbs out would cause issues, but the LEDs lit up fine even with the bottom bulb slots left empty. Then I noticed the turn signals were hyper flashing. I put an old bulb back in on one side with the LED to see if I could get the LED to stop hyper flashing, they still do it.

Working on contacting LASFIT support to see what my options are. Looking at other reviews, I might just have a defective set of bulbs. When my headlights are on, my LED turn signals stay on as running lights - not sure they're supposed to be doing that. Typically my running lights aren't on unless I manually cut my headlights to running lights only. Maybe that's causing them to overheat, or maybe it's a defect?

Will update if I can get it fixed! I really want them to work.

**Update 1/30/23: Vichan is the man. I contacted customer service and they wanted to send me 2 additional turn signals. USPS said theyd come the following Monday (today) but they came in last Saturday. I put them in the same night. No more hyperflash.

I am beyond impressed with the lights I have, and beyond impressed with Lasfit's customer service. I'd recommend them to anyone. Get you some.

My low beams can light up a field. The fog lights have already helped me get to work twice through the swamps. My high beams are as bright as the sun. Beyond impressed. I'll be replacing my rear lights soon.

Had swapped out my hid high/low beams for these, lasfit bulbs are like miniature suns. Had to loosen both headlights to get them in, fans are rather large. Hence the 4 stars. It was just enough that they wouldn't go in without pulling the headlights out 1/2 an inch, they're very bright and have a very pure white color to them. Also wish they had supplied a proper diagram on how to clock the bulbs. Quick YouTube video showed that the led chips have to be at 3 and 9 o clock. Only had them in for about two days and I'm very satisfied with them and I hope I get several years out of them.
