Mercedes-Benz GLE350 high beam and low beam headlight bulbs both use H7 size. The replacement chart covers 2016 to 2020 vehicle production years with bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H7 bulb is the sole bulb type listed across all headlight positions in the Mercedes-Benz GLE350 specifications, covering both high beam and low beam functions for the 2016-2020 model years included in the data.
The H7 is a single-filament halogen bulb operating at 55 watts on a 12-volt system, housed in a compact capsule form with a PX26d two-pin base that locks into the headlight assembly with a twist-and-lock mechanism.
The 2016 and 2020 model years carry an explicit notation of "With Halogen Capsule Headlamps," indicating that the H7 fitment applies specifically to vehicles equipped with that headlamp configuration rather than to all trim or equipment variants of those years.
The 2017 and 2018 model years list the H7 without a conditional notation, suggesting the halogen capsule headlamp system was the standard configuration for those years without documented alternative headlamp types in these specifications.
Because the H7 is shared across both the high beam and low beam positions, the GLE350 headlamp assemblies for the listed years use separate single-filament bulbs for each function rather than a dual-filament unit handling both beams from a single source.
The PX26d base of the H7 is not interchangeable with other common halogen bases such as the H4 or H11, and substituting a physically similar but differently based bulb risks improper seating, electrical incompatibility, or damage to the headlamp housing.
Vehicles equipped with non-halogen headlamp systems, such as bi-xenon or LED assemblies, fall outside the scope of these specifications, and the H7 fitment noted here does not apply to those configurations.
