Fuelmiser Brake Light Switch CSL127 is listed as a switch in the electrical parts and engine management groups, with the item type recorded as Brake Light Switch. It is supplied as each and weighs 0.5 kg, which is useful to note when matching against the existing unit and when checking freight or packaging needs.

The key identifier for ordering is Part No. CSL127. The brand is Fuelmiser, and the product is described as a Fuelmiser Brake Light Switch. For buyers cross-checking against an existing vehicle part, the part number and item type are the most practical references to confirm before purchase.

Application and Buying Notes

The most reliable way to buy this part is to match the vehicle application and the part number CSL127 together. The listing identifies it as a Fuelmiser Brake Light Switch, and the fitment information references Mercedes-Benz and Volkswagen applications, but brake light switch selection should still be checked against the existing unit on the vehicle. That is especially important where a range includes multiple model years such as A-Class 2004 to 2012, B-Class 2005, and Volkswagen Crafter 30-50 2006 to 2013.

The two-year warranty is a useful reference, but it should not be used as a substitute for fitment confirmation. If the original switch has a different part number, connector style, or application reference, compare those details carefully before fitting. The listed weight of 0.5 kg and the fact that the item is supplied as each may also help when checking the replacement against the removed part.

Fuelmiser states that this switch is manufactured to OEM specifications, which generally means the part is intended to match the original specification rather than being a universal substitute. Even so, the practical buying check is the same: verify CSL127, confirm the vehicle’s application, and make sure the brake light switch you are replacing matches the same vehicle group and model-year coverage shown here.

For trade buyers or workshop use, it is worth checking the vehicle identification details alongside the part number before finalising the order. The fitment range covers several Mercedes-Benz and Volkswagen entries, but not every vehicle in those model families will necessarily use the same switch. Careful checking upfront reduces the chance of returns and avoids fitting a part that looks similar but is not the correct application.

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.

Compatibility note: Please confirm compatibility using Part No. CSL127 and the vehicle’s specific application details before ordering. The listed fitment covers selected Mercedes-Benz and Volkswagen applications, but final confirmation should always be made against the existing part and vehicle build.
