Application and Buying Notes

When replacing a stop light switch, the safest approach is to match the part number TBS138, then confirm the circuit type and connector layout against the vehicle’s original switch. This item is specified as a resistance circuit switch with 3 pins, and those details matter because the wrong circuit or pin count can lead to an incorrect electrical match even if the part looks similar.

The fitment information supplied for this listing includes Holden Calais, Holden Caprice, Holden Commodore, Holden Statesman, and HSV models such as Clubsport, Grange, GTS, Maloo and Senator. If your vehicle is one of these, check the exact application carefully against the original part number and the vehicle’s existing stop light switch before buying.

No spanner size or thread detail is provided for this part, so do not assume it shares the same mounting or thread arrangement as another switch. The correct comparison points here are the TBS138 part number, the 3 pin layout, and the resistance circuit specification.

This is supplied as a single each unit, so it suits replacement of one switch at a time where that is all that is required. If you are diagnosing brake light operation, compare the fault symptoms with the vehicle’s switch arrangement and make sure the replacement matches the electrical setup already fitted to the car.

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 TBS138 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.
