Tridon Stop Light Switch TBS137, 4 Pin

The Tridon Stop Light Switch, part number TBS137, is a switch supplied as an each unit and listed under Micks Gone Bush in the auto elec accessories and fuses, breakers, relays, switches product groups. It is identified with 4 pins, which is a key matching point when checking a replacement against the existing switch before ordering.

This unit sits in the vehicle control side of the electrical system and is intended for stop light switch applications. The provided fitment data includes Audi applications, with preview coverage showing A4 models from 2007 through 2015 and A4 Allroad entries, so the part number and connector detail should be checked carefully against the original unit already fitted to the vehicle.

A two year warranty is listed for this Tridon switch. For a safety-related electrical part such as a stop light switch, the correct identification is important because the switch must suit the vehicle application, connector style, and the way the original part is mounted.

The product information supplied here does not list thread, spanner size, or circuit detail, so those fields should be matched from the original component rather than assumed. If you are replacing a stop light switch on an Audi application, use the part number TBS137 and the 4-pin layout as the first confirmation points before purchase.

Application and Buying Notes

When replacing a stop light switch, the most reliable checks are the part number TBS137, the 4-pin connector, and the vehicle application already on the car. Even where a model family appears in the fitment data, the exact switch used can vary, so the original unit should be compared before the part is fitted.

The supplied information lists no thread, spanner size or circuit detail, which means those measurements should be treated as unknown unless they match the part removed from the vehicle. This is particularly important on electrical switches where connector style and physical mounting must align with the existing pedal or brake switch arrangement.

For Audi applications shown in the fitment preview, the A4 range is specifically represented across multiple model years, and A4 Allroad is also listed. If the vehicle is one of the other Audi models in the fitment make list, confirm the application carefully rather than relying on the model name alone.

The warranty listed is two years, which provides a clear product reference point, but it does not replace the need to verify fitment. In practice, the safest buying approach is to match the old switch, check the connector face, confirm the mounting arrangement, and make sure the vehicle’s application details line up with TBS137.

As a stop light switch is part of the braking signal circuit, a correct match matters for both function and warning-light behaviour. If the existing switch is damaged, remove it first and compare the identification, pin count and physical layout against the replacement before installation.

This item is sold individually, so if more than one switch or related component is being replaced, check the vehicle carefully before ordering quantities. Using the part number and the 4-pin configuration as the main reference points will help avoid a mismatch and reduce return risk.

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 TBS137 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.
