Tridon Stop Light Switch TBS054

The Tridon Stop Light Switch, part number TBS054, is a dual circuit switch supplied by Tridon as an individual each item. It is listed with a two year warranty and sits within the auto elec accessories and fuses breakers relays switches product groups, which makes it a relevant replacement item when dealing with stop lamp circuit faults.

This switch is described as a dual circuit unit with Normally Open and Normally Closed operation. That detail matters because stop light switches are not all the same, and the circuit type must match the vehicle application and wiring arrangement. The listed part number TBS054 is the clearest reference point when checking suitability.

The supplied information does not list a spanner size or thread specification, so those details should not be assumed. If you are comparing against an original switch, the safest approach is to match the part number, the circuit configuration, and the vehicle application before ordering. The fitment data includes Alfa Romeo and Fiat applications, including 147, 156, 159, 166, Brera, GT, GTV, Spider, Fiat 500, 500 C, Ducato, and Ritmo ranges.

Application and Buying Notes

When replacing a stop light switch, the main checks are the part number TBS054, the circuit type, and the vehicle application. This Tridon switch is a dual circuit unit with Normally Open and Normally Closed operation, so it should only be selected where that configuration matches the vehicle’s requirements. The fitment list provided includes Alfa Romeo and Fiat applications, but the exact vehicle match still needs to be confirmed before fitting.

The supplied product details do not include a thread specification or spanner size, so those items should be treated as unverified. If you are working from an existing part, compare the old switch carefully against TBS054 and check the application list for the relevant Alfa Romeo or Fiat model and year range. That is especially important on vehicles where electrical switch variants can change across production runs.

A stop light switch is part of the brake light control circuit, so a correct match matters for proper operation. The listed two year warranty applies to this Tridon item as supplied, but warranty cover does not replace fitment checking. If your original part has a visible number or the vehicle has a specific switch style, use that information together with the model list before ordering.

For buyers handling workshop or driveway repairs, it is worth confirming the switch location, connector style, and how the circuit operates on the vehicle before installation. The product is supplied as one each, so order quantity should be based on the number of switches required, not on the model list alone. Clear identification before installation helps avoid downtime and repeat removal work.

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 TBS054 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 TBS054 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS054, 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 147, ALFA ROMEO 147 2001, ALFA ROMEO 147 2002, ALFA ROMEO 147 2003, FIAT 500, FIAT 500 2007. 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.

Compatibility note: Please confirm compatibility using the part number TBS054 and the stated vehicle application details before ordering. Do not assume fitment from the make alone, and verify the circuit type, connector arrangement, thread details where applicable, and the vehicle’s exact model year.
