Keep your brake warning light working correctly with the Standard Ignition Parking Brake Switch DS-3369 (also written DS3369). This switch signals the vehicle's warning circuit based on the position of the parking brake, illuminating the dash brake-warning lamp when the parking brake is applied. It installs as a direct-fit OE replacement for the 2003 Ford Crown Victoria, 2003 Lincoln Town Car, 2003 Mercury Grand Marquis, and 2003 Mercury Marauder — see the Buyer's Guide tab for engine details.
If a faulty parking brake switch is the reason your brake warning light stays on, flickers, or fails to light when the brake is set, replacing it with the DS-3369 restores that circuit function. Diagnose the cause first, since a warning-light complaint can also come from brake fluid level, wiring, or other components.
