Mercedes-Benz E63 AMG S high beam and low beam headlight bulbs both use H7 size. The chart contains bulb size specifications for vehicle production years spanning 2014 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 across all listed headlight positions for the Mercedes-Benz E63 AMG S, appearing in both high beam and low beam applications.
The H7 is a single-filament halogen bulb operating at 55 watts with a PX26d base, a two-pin connector design that locks into the housing with a bayonet-style retaining clip.
High beam fitment is specified for the 2014-2016 and 2018-2019 model years, all using the H7 bulb size.
Low beam fitment is specified for the 2018-2019 model years, also using the H7 bulb size.
The H7 base type is not universally interchangeable with other common single-filament halogen types such as H1 or H11, despite similar wattage ratings, due to differences in pin configuration and socket geometry.
When both high beam and low beam positions share the same H7 specification, as is the case for the 2018-2019 E63 AMG S, the bulbs are physically identical but are housed in separate optical assemblies designed for distinct beam patterns.
Substituting an H7 bulb with a physically similar but electrically incompatible type risks improper seating in the housing, which can affect beam alignment and weatherproofing of the headlight unit.
