Fuelmiser Brake Light Switch CSL127

The Fuelmiser Brake Light Switch, part number CSL127, is a single switch sold each and listed under electrical parts and engine management. It is a straightforward replacement item for brake lamp circuit control, and the confirmed warranty is two years. For buyers comparing options, the key identifiers here are the Fuelmiser brand, item type Brake Light Switch, and part number CSL127.

Fuelmiser states that its range is sourced from world leading OEM and OES manufacturers, with aftermarket technology adapted to suit replacement use. The product is described as manufactured to OEM specifications, which makes the part number CSL127 and the application details especially important when checking compatibility. As with any brake light switch, the correct match depends on the vehicle's original setup rather than the general product name alone.

This switch is listed at 0.5 kg and supplied as an each unit, so it is a compact electrical replacement rather than a bulk service item. The fitment information provided includes Mercedes-Benz A-Class, B-Class, Sprinter 3-T and Sprinter 5-T applications, as well as Volkswagen Crafter 30-50 and 5-T and 6-T applications across multiple model years. Always confirm the exact application against the vehicle before ordering.

Application and Buying Notes

Before ordering, check the part number CSL127 against the existing brake light switch in the vehicle and compare the listed application details carefully. The same item type name, Brake Light Switch, is not enough on its own if the vehicle uses a different switch style or wiring arrangement. The supplied fitment data covers Mercedes-Benz and Volkswagen applications, including A-Class, B-Class, Sprinter 3-T, Sprinter 5-T and Crafter 30-50 references.

The two year warranty is a useful confidence point, but it does not replace proper fitment checking. Brake light switches are small electrical components, so the important checks are the part number, the vehicle model designation, and the model year shown in the fitment data. If your vehicle falls within the listed ranges, confirm the exact variant before fitting, especially where the application spans multiple years.

Because this is a switch sold each, it is suited to replacement of a single failed unit rather than a matched kit. The 0.5 kg listed weight gives a general sense of the component size, but the critical buying detail remains the compatibility match. If you are cross-referencing against an old part, CSL127 is the identifier to compare first, followed by the vehicle application details supplied for Mercedes-Benz and Volkswagen models.

For workshop and retail buyers alike, it is best to treat brake light switch selection as an exact-match exercise. The Fuelmiser description notes OEM specifications, which supports the need to compare the original part and the vehicle application rather than relying only on broad model families. When in doubt, confirm the original switch style, plug arrangement, and vehicle details before installation.

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 CSL127 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 CSL127 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number CSL127, 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 5-T 2006, 5-T 2007, 5-T 2008, 5-T 2009, 6-T 2009, 6-T 2010. 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 by matching part number CSL127 and the listed vehicle application details before purchase. Brake light switch compatibility can vary by model year and variant, so the model name alone is not enough.
