Save up to 7% vs. buying each set separately. The complete LumX LED upgrade for the low/high beams and fog lights on your 2014-2018 GMC Sierra. Pick a single set or the full package.
Why LumX
A focused beam that reaches farther. Automotive-grade multi-core LED chips sit as close as possible to where the original bulb's light comes from, so you get a tight, focused beam that lets you see farther down the road. Big lumen claims don't mean much. Beam focus does.
Premium tech, fair price. You get the technology of the leading LED sets at about 60% of the price. LumX sets cost more to make than most cheap LED headlight kits sell for.
Aluminum, not plastic. The bulb housing, retaining collar and fan housing are all aluminum. No cheap plastic parts to snap during install.
Quiet, sealed cooling fan. The dual-ball cooling fan holds up better against water and dust, and it's quiet enough that you won't hear it while parked. That was a common complaint about the previous version, and we fixed it.
Try them risk-free. If they're not for you, send them back with our 60-day hassle-free returns.
Install & fit
Fits at least 95% of vehicles. We gave the LumX set a smaller footprint than the previous version (which sold tens of thousands of sets and rarely had fit issues), so dust covers and tight engine bays usually aren't a problem.
Pre-aimed for you. Positioning is critical with any LED bulb. LumX bulbs adjust a full 360°, but we pre-set them so 9 times out of 10 they're aimed correctly the moment you plug them in.
Plug and play. Molded plugs fit your factory connectors.

Love the lights but light setup could be easier.
I have used many LEDs from Diesel LEDs LUMINEX Bulbs and all have been fantastic. I trust them to work as they say. 100%... I am rating these bulbs as a 3 only because the setup of the bulb was more of a headache and should be reviewed for better engineering. Trying to align the bulbs with socket is truly a pain. The set screw to lock the socket to the bulb should be longer and probably screwed into the socket to lock the socket better. BUT functon of the light is AMAZING... I have enough of these bulbs to know. I have helped others with these. I trust them. Overall, the setup could be better for this style of light for GMCs.

Headlight / fog light package
I am very pleased with the light these headlights and fog lights produce. However I have one currently that comes and goes every now and then. Therefore I ordered another set to be prepared when it went out for good. I am very pleased with dieselleds customer service, as I lost a fog light shortly after I installed my initial set 2 years ago. They sold me an individual one to help me out of my dilemma. That's the kind of customer I appreciate.
