The Mercedes-Benz CL65 AMG uses H11 and H7 bulbs for high beam headlights, while low beam headlights require D1S and D2S bulb sizes. The replacement chart covers 2005 through 2014 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H11 and H7 bulbs are the two halogen types specified for the high beam position in the Mercedes-Benz CL65 AMG. Both operate at 12V and 55W and follow the ECE standard recognized across Europe, the US, and other markets, though their bases differ: the H11 uses a PGJ19-2 base while the H7 uses a PX26d base. These two base types are physically incompatible with each other, meaning the bulbs are not interchangeable despite sharing identical voltage and wattage ratings.
The high beam position on the CL65 AMG used the H7 bulb from 2005-2010 and transitioned to the H11 bulb for 2011-2014. Because the PX26d and PGJ19-2 bases are distinct, a bulb from the earlier fitment group cannot be substituted into a housing from the later group.
The low beam position across all listed years uses HID (xenon) discharge technology rather than halogen. Both D1S and D2S bulbs operate at 85V and 35W and are designed for projector-type housings, but they differ in a critical way: the D1S has an integral ignitor built into the bulb itself, while the D2S requires a separate external ignitor within the vehicle's lighting system.
The D1S and D2S bulbs also differ in base type, with the D1S using a PK32d-2 base and the D2S using a P32d-2 base. This physical difference, combined with the ignitor configuration difference, means the two bulb types are not interchangeable even though their electrical output ratings are identical.
The low beam position on the CL65 AMG used the D2S bulb from 2005-2009 and shifted to the D1S bulb for 2010-2014. Vehicles from the D2S years have an external ignitor integrated into the housing circuit, while those from the D1S years rely on the ignitor housed within the bulb itself.
Both D-series HID bulb types listed carry ECE approval and are recognized internationally. The H7 additionally holds approval in Japan, giving it the broadest regional approval among the four bulb types specified.
All four bulb types in these specifications are single-filament designs. The halogen types achieve their output through a tungsten filament in a halogen gas environment, while the HID types produce light through an electrical arc discharge between electrodes in a xenon gas-filled arc tube, which accounts for the significant voltage difference between the two technologies.
