Tridon Stop Light Switch TBS078 M10 X 1.25 Dual Circuit

The Tridon Stop Light Switch, part number TBS078, is a switch sold each and supplied under the Tridon brand. It uses an M10 x 1.25 thread and a 14 mm spanner size, which are the key physical identifiers to check when matching it to the brake light switch position on the vehicle.

This switch is listed with a dual circuit arrangement: normally open and normally closed. That is a critical detail because some brake light circuits need both functions in the same unit, and the switch style must suit the vehicle’s wiring and operating logic.

It carries a two-year warranty and sits in the auto electrical accessories range. For the right application, the part number TBS078 is the most reliable identifier to compare against the old switch, the vehicle listing, and the thread and circuit details before purchase.

Application and Buying Notes

Brake light switches are simple parts, but the matching details matter. For this Tridon TBS078 unit, the thread is M10 x 1.25 and the spanner size is 14 mm, so the fitting point on the vehicle needs to match those dimensions before you rely on the part.

The dual circuit setup, with normally open and normally closed functions, is another point to confirm carefully. If the original switch does not use the same circuit behaviour, the brake light system may not operate as intended, so the vehicle’s existing switch specification should be checked against this one.

The fitment information supplied includes a wide range of Hyundai and Kia models, plus Nissan Patrol, but it is still best practice to compare the part number TBS078 with the removed switch and the vehicle application listing. Small differences in thread, circuit type, or connector arrangement can matter even when the model family appears similar.

Because this is a stop light switch in the auto electrical system, the safest buying approach is to verify the original part details before fitting. Matching the thread, spanner size, circuit type and stated application is the practical way to reduce the chance of a mismatch.

If you are replacing a failed brake light switch, inspect the old unit for the part number and threaded size where possible. That gives you a direct comparison point against the listed M10 x 1.25 thread and dual normally open / normally closed circuit on this Tridon switch.

The two-year warranty applies to the part as supplied, but it does not replace fitment checking. For a dependable result, use the vehicle application notes alongside the part number and physical dimensions, especially where the vehicle has had previous electrical repairs or non-original components fitted.

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 TBS078 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 TBS078 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TBS078, 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 HYUNDAI ACCENT, HYUNDAI ACCENT 2005, HYUNDAI ACCENT 2006, HYUNDAI ACCENT 2007, KIA CARNIVAL, KIA CARNIVAL / GRAND CARNIVAL. 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 fitment against part number TBS078, the M10 x 1.25 thread, 14 mm spanner size and the listed vehicle application details before ordering. Where the original switch differs in circuit type or thread, do not assume interchangeability.
