Application and Buying Notes

Confirm the replacement against the part number CSL137 before ordering. Brake light switches can look similar across different vehicles, but the correct electrical function depends on the exact application, not just the general shape of the component.

The stated fitment information includes Audi A3 and Volkswagen applications such as Beetle, Bora, Golf, New Beetle, and Touareg, but only the applications specifically shown in the fitment data should be used when checking suitability. If your original switch carries a different number, compare that number carefully with CSL137 before purchase.

Because this is an electrical part, it is worth checking the removed switch, connector style, and vehicle application details before fitting. The listing identifies this as a brake light switch made to OEM specifications, which is useful as a reference point when matching the replacement to the original part.

The two-year warranty applies to the supplied part, but warranty coverage does not replace the need to confirm fitment first. A brake light switch must suit the vehicle’s intended application and be installed correctly for the brake lamps to function as intended.

If you are comparing options, use the combination of brand, part number, item type, and vehicle application details rather than relying on appearance alone. The part is supplied each, so ensure you are ordering the required quantity for the job.

At .5kg, this part is relatively light, which may help when comparing packaging or replacement component weight, but weight alone is not a fitment guide. The most reliable checks remain CSL137, the brake light switch description, and the listed vehicle applications.

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.

Compatibility note: Please confirm compatibility by matching part number CSL137 and the listed vehicle application details before ordering. If your vehicle is not shown in the fitment information provided, treat this as unconfirmed and verify with the removed part or vehicle records.
