Fuelmiser Brake Light Switch CSL191

The Fuelmiser Brake Light Switch, part number CSL191, is a switch assembly supplied as each and listed with a two year warranty. It sits in the electrical parts and engine management groups, which makes it a relevant replacement item when the brake lamp circuit needs attention and the existing switch is no longer operating correctly.

Fuelmiser identifies this brake light switch as manufactured to OEM specifications. That is an important point when you are replacing a switch that needs to work cleanly with the vehicle’s brake pedal or pedal-mounted actuation setup, because the switch must trigger the brake lights at the correct point of pedal travel.

This item is a genuine service-style replacement part rather than a universal accessory. The stated weight is 0.3 kg, and the listed product type is switch. When checking a replacement, the part number CSL191 and the brake light switch application matter more than a general description alone.

Fitment data supplied for this listing includes Mazda applications only, with grouped references covering Mazda 2, Mazda 6, Mazda CX-7, Mazda CX-9, Mazda MX-5 and Mazda RX-8 across multiple model years. If you are matching a Mazda vehicle, compare the exact application details carefully against your vehicle identification before ordering.

Application and Buying Notes

When selecting a brake light switch, the best starting points are the part number CSL191, the vehicle application, and the way the switch mounts and operates on your vehicle. The supplied fitment data points to Mazda applications, including Mazda 2, Mazda 6, Mazda CX-7, Mazda CX-9, Mazda MX-5 and Mazda RX-8, but the exact year and variant still need to be checked against the vehicle you are repairing.

A brake light switch is a safety-related electrical part, so the switch must match the original function closely. Fuelmiser states this item is manufactured to OEM specifications, which is the key compatibility cue here. That means the intended replacement should be compared carefully with the original switch in both part identification and application details before fitting.

The listed two year warranty applies to this part, and the unit of measure is each. For workshop or home repairs, that helps clarify you are buying one switch assembly rather than a kit. The 0.3 kg weight also gives a sensible indication that this is a compact electrical component rather than a larger control module.

If the brake lights have become intermittent, delayed, or remain on, the switch is one of the first components to inspect. Even so, diagnosis should be based on the vehicle’s existing setup and the actual part reference CSL191, not just on the general description of a brake light switch. Matching the application remains the safest way to avoid the wrong replacement.

For Mazda vehicles in particular, compare the model, year, and any relevant variant information against the supplied application list before ordering. A brake light switch can be similar across different platforms, but small differences in actuation or mounting can affect whether the part is suitable. Confirming the exact application is the most practical way to keep the repair straightforward.

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 CSL191 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 CSL191 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number CSL191, 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: Confirm fitment by matching part number CSL191 with your vehicle application details before purchase. The supplied fitment references Mazda 2, Mazda 6, Mazda CX-7, Mazda CX-9, Mazda MX-5 and Mazda RX-8, but the exact year and variant should still be checked against the vehicle.
