Application and Buying Notes

Brake light switches are small components, but they have a direct impact on stop lamp operation, and the wrong switch can create ongoing faults or repeated replacement. This Fuelmiser unit is identified by part number CSL108, so the first step is to match that number against the vehicle application rather than relying on general shape or brand alone.

The fitment information shown here covers Audi 80, Audi A4, Audi A6, Audi A8 and Volkswagen Passat applications, with sample years including Audi 80 from 1986 through 1994 and Volkswagen Passat from 1998 through 2005. If you are working on one of these vehicles, check the exact year and specification carefully before purchase, because vehicle naming alone is not enough to confirm compatibility.

Manufactured to OEM specifications, this switch is intended to align with the original design standard for the listed application, but that does not remove the need for a proper match. Brake light switch fitment can depend on the vehicle’s exact model year and setup, so confirming the application details and the part number together is the safest way to buy once and fit once.

The two-year warranty applies to this Fuelmiser switch, which gives a clear reference point for supply confidence, but it is still important to verify the installation requirements before fitting. If the original part has been removed already, compare the replacement against the removed item and the vehicle records so the new switch is suitable for the car in front of you.

For freight, stock intake or workshop planning, the listed weight of 0.5 kg and the each unit measure are useful practical details. They help when comparing this item with other brake switch options, but the key compatibility checkpoint remains the same: confirm CSL108 against the vehicle application before committing to the part.

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 CSL108 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.

Fuelmiser Brake Light Switch. Part number CSL108 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number CSL108, 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.

Compatibility note: Please confirm fitment using part number CSL108 and the vehicle application details before ordering. Brake light switch compatibility should be checked against the exact model, year and configuration listed for the vehicle.
