The Mercedes-Benz SLK230 high beam headlight bulb uses H7 size, while low beam headlight bulbs are available in H7, D2S, and D2R sizes. The replacement chart covers vehicle production years from 1998 to 2004 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 H7 bulb is the most frequently specified type across these headlight specifications. It is a single-filament halogen bulb operating at 12V and 55W, fitted with a PX26d base, and recognized under ECE standards with approval also extended to the United States and Japan.
The Mercedes-Benz SLK230 uses the H7 bulb for the high beam headlight across all model years from 1998-2004 without variation.
Low beam fitment for the 2000, 1999, and 1998 model years is exclusively H7, while 2001-2004 model years present two distinct options depending on the headlamp system installed at the factory.
On 2001-2004 vehicles equipped with halogen capsule headlamps, the low beam bulb is the H7, the same type used in the high beam position.
On 2001-2003 vehicles equipped with HID headlamps, the low beam bulb is the D2R, a high-intensity discharge xenon type designed specifically for reflector-type housings, operating at 85V and 35W with a P32d-3 base.
The 2004 model year with HID headlamps specifies the D2S rather than the D2R. The D2S carries a P32d-2 base and is intended for projector-type housings, making it physically and optically incompatible with the reflector-type housing that accepts the D2R.
Both D2S and D2R bulbs require an external ignitor to initiate the high-voltage arc necessary for operation, a requirement that does not apply to the H7 halogen type.
Substituting a D2S for a D2R or vice versa is not supported by these specifications, as the two bulb types use different bases and are matched to different housing geometries.
