What is the headlight model of the new Buick GL8?
4 Answers
The headlight model of the new Buick GL8 is H7. Car bulbs are essential for ensuring driving safety and illuminating the road during nighttime driving, providing higher brightness and better visibility, thereby enhancing driving comfort and safety, and ensuring the safety of the driver. In terms of appearance, the new Buick GL8 maintains its exterior design, featuring a vertical waterfall grille paired with a winged chrome strip. The winged chrome strip runs through the double-layer combination full LED headlights, which have a rich layered design, giving the overall appearance a strong and powerful feel. Regarding body dimensions, the new Buick GL8 measures 5203 mm in length, 1878 mm in width, and 1805 mm in height, with a wheelbase of 3088 mm.
The specific headlight model for the Buick GL8 depends on which year's version you buy. My 2023 GL8 Landry uses matrix full LED headlights, which don't require separate bulb replacement as the entire light assembly is integrated. For older models like the 2017 GL8, I remember the high and low beams both use H7 halogen bulbs, and the fog lights use H11. Always check the manual before buying bulbs, as different batches may vary! Aftermarket bulbs are cheaper but prone to light decay. Once, I took the easy way out and used an aftermarket bulb, but the illumination on the highway at night was like candlelight, which scared me into switching back to the original Philips bulbs immediately. Also, be cautious when modifying to LED; poor heat dissipation can cause the lens to yellow.
Our service station replaces GL8 headlights every day, and the bulbs vary across its three generations. For example, post-2020 models have fully switched to LED modules—if they fail, you can only replace the entire assembly, with dealership quotes around 5,000 yuan. Models from 2014 to 2019 mostly use separate halogen bulbs: H7 for low beam, HB3 (also called 9005) for high beam, and H11 for fog lights. Last week, an owner installed self-purchased LED bulbs but experienced flickering and error codes, eventually realizing a decoder was needed. We recommend owners check the headlight base—original bulbs are engraved with model numbers, and Osram Night Breaker series offers the best compatibility. Converting to xenon lights is more complex, requiring projectors to avoid glare.
Just studied the GL8 headlight specs! The current models all feature integrated LED units without separate bulb replacements, but older versions are quite particular: for example, the 2018 Classic Edition uses H7 for low beams, 9005 for high beams, and H11 for fog lights. Note that some owners mistakenly purchase H1 or 9006 bulbs, which simply won't fit. During my headlight modification, I discovered a lesser-known fact—the GL8's high beam socket has three prongs; buying a two-pronged LED will immediately cause issues. I recommend Osram Laser Night Breaker with a 5800K color temperature—its rain penetration is far superior to those bluish 6000K options. When upgrading to LEDs, always choose models with cooling fans, or you risk melting the reflector bowl. By the way, the rear license plate light uses T10 bulbs, which can be easily replaced while you're at it.
