Mercedes-Benz GLE43 AMG high beam and low beam headlight bulbs both use H7 size replacement bulbs. The chart contains bulb size specifications covering 2017 to 2019 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 with a nominal voltage of 12 volts, classified under the PX26d base designation, which defines the physical pin configuration used to seat the bulb in its housing.
Both the high beam and low beam headlight positions on the Mercedes-Benz GLE43 AMG use the H7 bulb across the 2017-2019 model years.
Because the high beam and low beam positions share the same H7 specification, the vehicle uses a projector or reflector system with separate dedicated housings for each function rather than a single dual-filament bulb to handle both tasks.
The H7 format is not interchangeable with visually similar single-filament types such as H1 or H3, as those types use different base configurations and pin arrangements that are physically incompatible with H7 sockets.
H7 bulbs are also distinct from H4 bulbs, which carry a dual-filament design and a different base type; substituting an H4 in an H7 socket is not possible without modification.
The PX26d base on the H7 bulb incorporates a locating tab that ensures the bulb is seated in only one orientation, which is relevant to maintaining the correct light beam pattern as defined by the vehicle's optical housing geometry.
