Fuelmiser Brake Light Switch CSL125

The Fuelmiser Brake Light Switch, part number CSL125, is a single switch supplied as each and listed under engine management and electrical parts. It is identified as a brake light switch and is manufactured to OEM specifications, which makes it a straightforward replacement choice when the existing switch is no longer operating correctly.

Fuelmiser states that its parts are sourced from world leading OEM and OES manufacturers, with technology adapted for the aftermarket. For a brake light switch, that matters because the correct switching action is what tells the stop lamps to operate when the pedal is pressed, and the part needs to match the application properly rather than just look similar.

This item carries a two-year warranty and has a listed weight of 0.5 kg. Those details do not confirm vehicle fitment on their own, but they do help when comparing replacement options and checking that you have the right component before ordering.

The part is sold under the Fuelmiser brand and the product type is SWITCH. If you are replacing a brake light switch, the safest approach is to match the part number CSL125 and confirm the application details against your vehicle before purchase.

Application and Buying Notes

A brake light switch is a small electrical component, but the correct match is important because it controls the stop lamps when the pedal is operated. This Fuelmiser unit is identified as part number CSL125, so that number should be your first check against the original switch or your vehicle parts listing.

The fitment data references Ford and Mazda vehicles, including Ford Ecosport, Escape, Focus, Kuga, Mondeo, Mustang, Ranger and Transit, along with Mazda 2, 3, 6, CX-3 and CX-5. Where a vehicle appears in the application list, confirm the exact model, year and any other vehicle details before fitting, because similar models can use different switches.

The product is described as manufactured to OEM specifications and sold as each, with a listed weight of 0.5 kg. Those details are useful when comparing like-for-like replacements, especially if the original switch is being matched by size, connector style or mounting arrangement, but they do not replace a proper fitment check.

Fuelmiser notes that its range is sourced from OEM and OES manufacturers and adapted for the aftermarket. That gives useful context about the product position, but the practical buying step is still to verify CSL125 against the vehicle application and the removed part before completing the order.

If your existing brake light switch has intermittent operation, no stop lamp output, or a mismatch in the physical part number, this listing may be the right type to compare. Keep the original part on hand where possible and check the application notes carefully, as the provided fitment covers more than one make and model family.

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 CSL125 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 CSL125 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

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.
