Tridon Stop Light Switch TBS031

The Tridon Stop Light Switch, part number TBS031, is a switch supplied as each and listed for automotive electrical accessory use. It is identified as a normally closed circuit switch, which is the key electrical detail to confirm before ordering or replacing a brake light or stop light switch.

This listing carries the Tridon brand and a two-year warranty. The product grouping places it under fuses, breakers, relays and switches, which is consistent with its role in vehicle electrical control rather than a mechanical wear item.

The basic service details are straightforward: the unit of measure is each, the description is Tridon Stop Light Switch, and the recorded feature data does not specify a spanner size or thread size. That makes the part number TBS031 and the circuit type the main identifiers to check against the vehicle application.

Fitment data supplied with this product includes Alfa Romeo applications, with previewed references for Alfa Romeo 166, GTV and Spider variants. As always, the exact vehicle match should be confirmed against the part number and the application details before purchase.

Application and Buying Notes

Before buying, match the part number TBS031 and the electrical detail marked normally closed. For a stop light switch, the circuit type is one of the most important checks because it determines how the switch behaves in the vehicle’s brake light circuit.

The listed data does not provide a spanner size or thread size, so do not rely on those measurements for identification. If the original switch is available, compare the old unit’s markings, connector arrangement and the application details for the vehicle before ordering.

The fitment preview includes Alfa Romeo 166, GTV and Spider references, but those references should be treated as application guidance rather than a universal guarantee. A careful check of the exact vehicle model and year against TBS031 is the safest way to avoid an incorrect purchase.

This part is supplied as each, which suits a direct replacement when only one switch is required. The two-year warranty is also listed, but it does not replace the need to confirm compatibility on the vehicle side before fitment.

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 TBS031 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 TBS031 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS031, 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 ALFA ROMEO 166, ALFA ROMEO 166 1999, ALFA ROMEO 166 2000, ALFA ROMEO 166 2001. 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 part number TBS031, the normally closed circuit detail, and the relevant vehicle application information before ordering.
