Application and Buying Notes

For a stop light switch, the two details that matter most are the part number and the circuit type. Here the part number is TBS029 and the circuit is Normally Closed, so those should be matched carefully to the replacement unit already fitted to the vehicle. The listing does not provide a spanner size or thread specification, so those physical details should be checked on the vehicle or against the removed part before ordering.

This switch is sold as each, which is useful when you only need one replacement component rather than a kit. The product is identified as Tridon Stop Light Switch, and the warranty period is two years. If you are comparing options, make sure the vehicle application and connector or mounting arrangement line up with the part already installed.

The fitment data references BMW applications, including BMW 3, BMW 5, BMW 7 and BMW Z3, with BMW 3 shown across multiple years in the preview. Even with that reference, the safest buying method is still to confirm the original part number, because stop light switches can vary by circuit style and fitment details that are not always obvious from the vehicle model alone.

If you are unsure after checking the old switch, compare the listed TBS029 number, the Normally Closed circuit, and any physical details you can verify from the removed part. That approach reduces the risk of ordering the wrong switch, especially where the listing does not provide thread or spanner measurements.

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 TBS029 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 TBS029 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS029, 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 BMW 3, BMW 3 1980, BMW 3 1981, BMW 3 1982. 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: Please confirm fitment using the TBS029 part number and the vehicle application details before ordering. The supplied fitment reference includes BMW applications, but any replacement should still be checked against the existing switch, circuit type and mounting details.
