Swag Brake Light Switch 4 Pin Pressure Switch Control Part No. 99 90 6035

The SWAG Brake Light Switch is an electrical switch with pressure switch control, supplied as one each and identified with part number 99 90 6035. It uses 4 connectors and is listed under electrical parts and engine management, which makes it important to match the switch style and connector count before ordering.

This part is described as OEM fit and OEM-matching quality, with reliable, durable and precise manufacturing. It is a compact component at 0.002kg, so the practical buying check is not physical size, but correct application, connector layout and the part number 99 90 6035.

SWAG lists this brake light switch with a one year warranty. For workshop and retail buyers, that gives a clear reference point, but the safest way to confirm the right part is to compare the vehicle application, the 4 connector arrangement and the part number against the existing switch already fitted to the vehicle.

Application and Buying Notes

Before ordering, compare the removed switch with this unit’s 4 connector layout and confirm the part number 99 90 6035. Brake light switches can look similar across different models, but connector count, control design and application details need to line up for a proper match.

The listed pressure switch control is an important detail because it describes how the switch operates within the system. If the vehicle uses a different style of brake light switch, the plug arrangement or control method may not suit, even if the switch appears physically similar.

This SWAG switch is catalogued for BMW 3 series applications from 1990 to 2000 and LAND ROVER Discovery applications from 1989 to 1998, with additional BMW and Land Rover groupings also listed. Use that as a guide only and confirm the exact vehicle and year against the part number, as grouped fitment still needs checking at vehicle level.

At 0.002kg, the switch is a small electrical component rather than a heavy mechanical part. That makes accurate identification by connector count, function and part number even more important than size. For workshop use, it is sensible to compare the old unit, the plug and the vehicle application before fitting.

The one year warranty applies to the product as supplied, but warranty coverage does not replace fitment checking. If you are replacing a brake light switch, verify that the electrical connector, mounting style and listed application match your vehicle before purchase to reduce the chance of an incorrect order.

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 99 90 6035 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.

SWAG Brake Light Switch. Part number 99 90 6035 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

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 BMW 3, BMW 3 1990, BMW 3 1991, BMW 3 1992, LAND ROVER DISCOVERY, LAND ROVER DISCOVERY 1989. 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 fitment using part number 99 90 6035, the 4 connector layout and the listed vehicle application before ordering. Where model grouping is shown, it should be treated as a guide and checked against the vehicle’s existing switch and connector configuration.
