Second Hand Mercedes-Benz 190E Brake Light Switch

Yes, every variant of the Mercedes-Benz 190E (W201, produced 1982–1993) was fitted with a brake light switch as standard — it sits on the brake pedal assembly and tells the brake lights to illuminate when you press the pedal. This applies to all engine variants from the 1.8 to the 2.6, so you won't be searching for a part that doesn't exist on your car.

The W201 190E ran as a single generation throughout its life from 1982 to 1993, with a facelift arriving around 1988 that mainly affected trim and exterior details rather than the brake pedal assembly. The brake light switch is mounted on the pedal box, which was not significantly revised at the facelift, so early and late switches are generally considered interchangeable — but confirm the part number against your registration with the breaker before buying, as minor production changes can exist across that boundary.

The brake light switch itself operates purely on the brake pedal mechanism rather than the braking system's hydraulic components, so engine size does not alter which switch you need. A switch from a 190E 1.8 should be the same unit as on a 190E 2.6 — the breaker can cross-reference the part number against your reg to be sure, but this is one area where engine size is very unlikely to make a difference.

Trim level makes no difference to the brake light switch on the 190E — the pedal box and switch location are the same regardless of whether your car was a base model or a higher-specification variant. The switch is a mechanical and electrical component rather than anything cosmetic, so don't filter your search by trim when sourcing one from a breaker.

The W124 and W201 are different platforms and the brake light switches, while superficially similar, may differ in thread size, plunger travel, or connector type, so cross-platform fitment is not straightforward. It is worth asking a breaker to compare part numbers directly, but sourcing a switch from another 190E (W201) is always the safest starting point to avoid compatibility issues.

Generally speaking, the W201 190E used a consistent pedal box design across the full 1982–1993 production run, so switches from any year within that range are widely regarded as compatible. That said, small mid-production updates can occasionally affect electrical connectors or thread specifications, so ask your breaker to verify the part number matches your specific registration rather than assuming all years are identical.
