Mercedes-Benz GLE63 AMG S high beam and low beam headlight bulbs both use H7 size. The chart contains bulb size specifications for vehicle production spanning 2016 to 2019.
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 these specifications, covering both high beam and low beam functions for the 2016-2019 model years.
The H7 is a single-filament halogen bulb operating at 55 watts on a 12-volt system, housed in a PX26d base with two pins offset at opposing positions to ensure correct orientation during installation.
The Mercedes-Benz GLE63 AMG S uses the same H7 bulb size for both the high beam and low beam headlight positions across all listed model years, meaning the two positions share a physically identical bulb type.
Although the high beam and low beam positions accept the same H7 bulb type, they remain separate, dedicated housings. A single dual-filament bulb does not serve both functions simultaneously in this configuration.
The H7 specification remained consistent across the full 2016-2019 range without variation, indicating no mid-cycle change to bulb type occurred during that period for either headlight position.
The PX26d base of the H7 bulb is keyed, meaning it is designed to fit in only one rotational orientation within its socket, which is a relevant factor during bulb replacement to avoid misalignment of the filament relative to the reflector or projector housing.
H7 bulbs are available in multiple variants, including standard halogen, extended-life halogen, and HID or LED retrofit forms, though the specifications list only the H7 designation without specifying a technology type beyond the base fitment code.
Because both the high beam and low beam positions share the H7 fitment, a single replacement bulb part number is applicable to either socket, though the quantity required for a full headlight service across both positions and both sides of the vehicle is four bulbs total.
