{"product_id":"0005452812oe-brake-light-switch","title":"Mercedes Sprinter Brake Light Switch – Genuine Mercedes-Benz | All Generations | #0005452812 (2001+)","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eA failed brake light switch on a Mercedes Sprinter means the brake lights don't illuminate when the pedal is pressed — an immediate safety hazard and equipment violation that puts the van and everyone behind it at risk, and also disables cruise control cancellation and the transmission shift interlock on equipped models. This is the Genuine Mercedes-Benz brake light switch for all Sprinter generations, a direct replacement that restores reliable brake light activation and proper safety system integration.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhat This Part Does\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe brake light switch is a mechanical contact switch mounted behind the brake pedal on the pedal bracket. When the brake pedal is pressed, the pedal arm releases the switch plunger, closing the circuit and sending power to the brake light circuit — illuminating all rear brake lamps simultaneously. The switch also provides a brake-applied signal to the cruise control system (canceling cruise when the brake is pressed), the transmission control module (enabling shift out of Park on automatics), and the vehicle's safety systems. When the switch's contact wears, its plunger spring weakens, or the switch body cracks, the brake lights become intermittent or fail entirely — and the associated safety interlock functions lose their brake signal.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eCommon Symptoms of a Failing Brake Light Switch\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBrake lights not illuminating when the pedal is pressed\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBrake lights that stay on continuously even when the pedal is released\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCruise control that won't disengage when the brake is pressed\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eInability to shift out of Park on automatic transmission models\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBrake light fault codes stored in the ECU\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhen to Replace\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eReplace when brake light function is confirmed absent or intermittent and the bulbs and fuses have been ruled out as the source.
