Fuelmiser Brake Light Switch CSL121 is a switch-type electrical part supplied as each, with a two-year warranty and a listed weight of 0.5 kg. It sits within the electrical parts and engine management groups, which is useful when matching the item against the correct vehicle application and part number before ordering.

The part is identified as a brake light switch under Fuelmiser part number CSL121. Fuelmiser states the range is sourced from world leading OEM and OES manufacturers and manufactured to OEM specifications, which makes the part number and application details the key checks when selecting a replacement.

This switch is intended for vehicles in the Volkswagen and Skoda groups shown in the fitment data, including Skoda Fabia and Volkswagen Polo variants. Because brake light switch designs can vary between model years and trims, the safest approach is to confirm the listed part number CSL121 against the existing switch and the vehicle application before purchase.

Application and Buying Notes

Before ordering, confirm the existing brake light switch part number matches CSL121 and compare the vehicle application carefully against the fitment list. The supplied fitment covers Skoda Fabia model years 2010 to 2014 and Volkswagen Polo model years 2001 to 2009, so the year and model details matter just as much as the brand name.

A brake light switch is a small electrical component, but the correct specification still matters. This Fuelmiser switch is listed as manufactured to OEM specifications, which makes it important to match the physical switch and connector details on the vehicle rather than assuming all brake light switches in a similar range are interchangeable.

The item is supplied as each and carries a listed weight of 0.5 kg, so it is a single replacement part rather than a kit. If your vehicle has been modified, has had steering column or pedal assembly work, or the old switch is unavailable for comparison, check the application carefully before fitting.

Fuelmiser notes this range is sourced from world leading OEM and OES manufacturers, and the product sits in both electrical parts and engine management categories. That makes it suitable for buyers who want the part number, application, and category to line up clearly before they commit to purchase.

If you are replacing a faulty brake light switch, make sure the symptom and the fitted component match the vehicle’s original arrangement. The brake light circuit depends on the correct switch operation, so using the part number CSL121 and the specified fitment details is the most reliable way to avoid ordering the wrong component.

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 CSL121 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.

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 SKODA FABIA, SKODA FABIA 2010, SKODA FABIA 2011, SKODA FABIA 2012, VOLKSWAGEN POLO, VOLKSWAGEN POLO 2001. 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: Confirm compatibility by checking part number CSL121, the vehicle model and year, and the existing switch application before ordering. If there is any mismatch in connector style, pedal setup, or vehicle generation, do not assume fitment from the model name alone.
