2020 Chevrolet Blazer Headlight Bulb Size
The 2020 Chevrolet Blazer headlight bulb size is H11 for the low beams, 9005 for the high beams, and H11 for the fog lights, making it straightforward to upgrade the lighting on Chevy's boldest midsize crossover. For 2020, Chevrolet expanded the Blazer lineup with a new 2.0-liter turbocharged engine and an SS-like front end treatment that sharpened the already aggressive styling. Halogen headlights come standard on the L and LT, while the RS and Premier feature factory LED units with signature lighting accents. Swapping in 2020 Chevrolet Blazer LED headlights on the halogen trims delivers the same striking white output that makes the premium models stand out at night.
The 2020 Blazer sits near the top of search results for good reason — it is one of the most visually distinctive crossovers in its class, and owners want headlights that reinforce that presence. The halogen bulbs that ship on the base trims simply do not match the vehicle's design language. LED or HID conversion kits solve that problem in under 30 minutes. Every HID Nation kit includes free shipping and a lifetime warranty.
LED and HID Options for the 2020 Chevrolet Blazer
An LED conversion kit for the 2020 Blazer fits the factory H11 low beam socket with no rewiring or housing changes. The bulb locks in with the same twist mechanism as the halogen, and the LED driver is compact enough to sit behind the headlight assembly without interfering with the dust cover. Output shifts immediately to a clean 6000K white that transforms the Blazer's front end after dark. Because the fog lights also use H11, upgrading all four positions at once gives you a fully matched white appearance across the entire front lighting array.
HID xenon kits appeal to Blazer owners who want maximum beam projection for nighttime highway cruising. The xenon arc creates a wider, denser beam pattern that pushes light further down the road. Each HID bulb connects to a slim ballast that tucks into the engine bay. Installation is slightly longer than LED at around 35 to 40 minutes for both sides, but the increased throw distance is worth the extra time for drivers who regularly cover long distances after dark.
All HID Nation kits ship free with a lifetime warranty. If a bulb or component fails, we replace it at no charge for as long as you own the vehicle.
