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.
Frequently Asked Questions
What is the 2019 Chevrolet Blazer headlight bulb size?
The 2019 Chevrolet Blazer uses H11 bulbs for the low beams, 9005 bulbs for the high beams, and H11 bulbs for the fog lights. This fitment applies to the halogen-equipped L and LT trims. The RS and Premier trims come with factory LED headlights that use integrated LED modules rather than replaceable bulbs. Since the low beams and fog lights both use H11, a single LED kit type covers four front bulb positions on the halogen trims.
Does the 2019 Blazer RS already have LED headlights?
Yes. The 2019 Blazer RS and Premier trims come standard with factory LED headlights that include a distinctive lighting signature. These factory LED units use integrated modules rather than a traditional replaceable bulb. The H11 LED conversion kits sold by HID Nation are designed for the halogen-equipped L and LT trims, not for vehicles that already have factory LED assemblies.
Will LED headlights match the 2019 Blazer's Camaro-inspired styling?
LED headlights are one of the most impactful visual upgrades for the halogen-equipped 2019 Blazer. The Camaro-inspired front end was designed to look aggressive and modern, but the dim yellowish output of halogen bulbs undercuts that intent. A 6000K LED conversion restores the clean, white look that the RS and Premier models achieve with their factory LEDs, giving the L and LT trims the same visual presence.
How long does it take to install LED headlights on a 2019 Blazer?
Most owners complete both low beams in about 20 minutes. Access the H11 bulb socket from behind the headlight housing in the engine bay, twist the retainer counterclockwise, and pull the old halogen out. Insert the LED bulb, lock it in place, and tuck the compact driver behind the assembly. Adding the H11 fog lights extends the total job to about 30 minutes since both positions use the same bulb type and procedure.
Are the 2019 and 2020 Blazer headlight bulbs the same?
Yes. The 2019 and 2020 Chevrolet Blazer share the same headlight housing design and identical bulb fitment: H11 low beam, 9005 high beam, and H11 fog light. An LED or HID kit that fits the 2019 Blazer will also fit the 2020 model without modification. The 2020 added a 2.0-liter turbo engine option, but the lighting hardware remained unchanged.
