2019 Chevrolet Blazer Headlight Bulb Size
Chevrolet revived the Blazer nameplate for 2019 as a bold two-row midsize crossover with Camaro-inspired styling that divided old-school fans but attracted a wave of new buyers, and the 2019 Chevrolet Blazer headlight bulb size is H11 for the low beams, 9005 for the high beams, and H11 for the fog lights. The base L and LT trims shipped with halogen headlights, while the RS and Premier came equipped with factory LED units featuring distinctive lighting signatures. Owners running halogen can close the gap instantly by upgrading to 2019 Chevrolet Blazer LED headlights that deliver the same bright white output as the premium trims.
The reborn Blazer's aggressive front end, with its narrow upper grille and wide lower opening, looks its best when the headlights match the vehicle's sporty attitude. Halogen bulbs wash that design out with a dim yellow glow that undercuts the Camaro-inspired styling cues. LED or HID conversion kits bring the lighting in line with the design intent. Every HID Nation kit includes free shipping and a lifetime warranty.
LED and HID Upgrades for the 2019 Chevrolet Blazer
An LED kit for the 2019 Blazer plugs into the factory H11 low beam housing without any wiring modifications. The LED bulb seats in the same socket as the halogen and delivers a clean 6000K white beam that dramatically changes the look and function of the headlights. Because the Blazer's headlight housing is designed around a wide, low profile, the improved light output from LED fills the lens area more effectively than halogen.
HID xenon kits are the option for Blazer owners who want the most raw light possible on the road. The xenon arc produces a wider hotspot with more beam density, which translates to better visibility at the far reaches of the headlight pattern. Each HID bulb requires a ballast, adding about 15 minutes per side to the installation. The Blazer's engine bay provides adequate space for ballast placement on both sides.
HID Nation ships every kit free and backs it with a lifetime warranty. If anything goes wrong, we handle the replacement at no cost to you.
