Tridon Stop Light Switch TBS122

The Tridon Stop Light Switch is a switch-type electrical part supplied as each, with part number TBS122 and a two-year warranty. It sits in Tridon’s auto electrical accessories range and is listed under fuses, breakers, relays and switches, which helps place it in the right category when you are matching a brake light switch to the vehicle’s electrical system.

The stated circuit detail is an open and closed multi pin circuit. That is a useful identifier when checking the replacement against the vehicle’s existing switch style, especially where the connector layout and switching action need to match the original part. The listed features also show Spanner: -, Thread: -, which means those physical identifiers are not supplied here and should not be assumed.

Fitment information is provided for Mercedes-Benz applications, including C-Class, CLK, E-Class, G-Class, M-Class, S-Class, SL, SLK and Sprinter variants across 2-T, 3-T, 4-T and 5-T ranges. Because brake light switches can vary by model year and electrical setup, the part number TBS122 and the vehicle application details should be checked carefully before purchase.

Application and Buying Notes

When replacing a stop light switch, the most important checks are the part number, connector style and circuit arrangement. This unit is identified as TBS122 and uses an open and closed multi pin circuit, so it should be compared with the original switch already fitted to the vehicle before ordering. If the vehicle has a different plug shape or circuit arrangement, the switch may not suit even if the vehicle badge appears in the fitment range.

The supplied fitment data points to Mercedes-Benz applications, but it does not narrow the match to a single series year or engine variant. That means model identification matters. Use the vehicle details already on the car, then compare them with the application list and the TBS122 part number rather than relying on the name alone.

The listed features do not provide thread or spanner measurements, so there is no basis here to specify installation dimensions or adjustment details. A careful installer will confirm the original switch’s mounting arrangement, connector count and switching operation against the replacement part before fitting. That is the safest way to avoid comebacks on a brake light circuit.

A two-year warranty is listed for this item, which provides a clear commercial reference point, but warranty cover does not replace fitment checking. The best results come from matching the vehicle application, electrical connector layout and part number together, particularly on Mercedes-Benz models where similar-looking switch parts can differ across generations and options.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number TBS122 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Tridon Stop Light Switch. Part number TBS122 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS122, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a switch in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include MERCEDES-BENZ C-CLASS, MERCEDES-BENZ C-CLASS 1993, MERCEDES-BENZ C-CLASS 1994, MERCEDES-BENZ C-CLASS 1995. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is Two Years. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by matching the TBS122 part number, the Mercedes-Benz application details, and the existing connector and circuit arrangement on the vehicle before purchase.
