Mercedes-Benz GLE400 high beam and low beam headlight bulbs both use H7 size replacement bulbs. The chart contains bulb size specifications covering 2016 to 2019 vehicle production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H7 bulb is a single-filament halogen type operating at 55 watts on a 12-volt system, housed in a compact capsule format with a PX26d two-pin base that locks into the headlight assembly via a bayonet-style retaining mechanism.
The Mercedes-Benz GLE400 uses the H7 bulb for both high beam and low beam headlight positions across the 2016-2019 model years covered in these specifications.
Because the same H7 bulb type is specified for both beam positions, the high beam and low beam housings each require a dedicated bulb rather than a single dual-filament unit serving both functions.
The 2016 Mercedes-Benz GLE400 carries a conditional fitment note specifying that the H7 bulb applies only to vehicles equipped with Halogen Capsule Headlamps, indicating that an alternative headlight system was also available for that year.
The 2017 and 2019 model years carry no equivalent conditional notation, meaning the H7 fitment for those years applies without a stated headlight system qualifier.
H7 bulbs are not interchangeable with visually similar single-filament types such as H1 or H4, as each designation corresponds to a distinct base configuration and envelope shape that is specific to its socket type.
