Address common brake light, cruise control, and gear selector issues by understanding this critical part.
- A faulty brake light switch is a critical safety issue and should be repaired immediately.
- Symptoms are not limited to brake lights; it can also prevent shifting from Park and disable cruise control.
- High-quality aftermarket brands like Standard Ignition offer a reliable, cost-effective alternative to expensive OEM parts.
- Replacement is a simple DIY task for most owners, requiring basic tools and about 30 minutes.
Is Your Jaguar Super V8 Showing These Symptoms?
A failing brake light switch can be misdiagnosed because its symptoms affect multiple systems. Before you suspect a major transmission or computer problem, check for these common signs of a bad brake light switch.
- Brake Lights Don't Work: The most obvious and dangerous symptom. The switch has failed and is not completing the circuit to turn the lights on.
- Brake Lights Stay On: The switch may fail in the 'on' position, leaving your brake lights permanently illuminated. This can drain your battery and confuse drivers behind you.
- Stuck in Park: Your car requires a signal that the brake is pressed before you can shift out of Park. If the switch is faulty, the signal is never sent, and your gear lever will be locked.
- Cruise Control Issues: The cruise control may not engage at all, or it might turn off unexpectedly. This happens because the system thinks the brakes are being applied.
- ABS or Stability Control Warning Lights: These systems rely on data from the brake switch. A bad signal can trigger a fault code and illuminate warning lights on your dashboard.
A Critical Safety Issue
Driving without functioning brake lights is extremely dangerous and illegal. If you suspect your brake light switch has failed, you should not drive the vehicle until it is repaired. Other drivers will have no warning that you are slowing or stopping, dramatically increasing the risk of a rear-end collision.
Choosing the Right Aftermarket Brake Light Switch
For the 2005-2009 Super V8, you do not need to pay high dealer prices for a reliable replacement brake light switch. Quality aftermarket brands offer a dependable solution for a fraction of the cost. The OEM part number for this vehicle is generally C2C36874.
- Standard Ignition (Standard Motor Products): A widely recognized and trusted brand in the aftermarket industry. Their switches are known for consistent quality and are a popular choice for European vehicles, offering performance similar to OEM without the high price tag.

Installation Snapshot
Replacing the brake light switch is a straightforward job that most DIYers can complete in under an hour. The switch is located above the brake pedal. The process involves disconnecting the electrical connector, removing the old switch (which may be held by nuts or a bayonet-style fitting), and installing the new one. The most challenging part is often the awkward position required to work in the driver's footwell.
Frequently Asked Questions
Can I still drive my Jaguar with a bad brake light switch?
No. If your brake lights are not working, the car is unsafe to drive and you risk being hit from behind. If the lights are stuck on, it can drain your battery and confuse other drivers. This repair should be made immediately.
Are there any recalls for the brake light switch on my Super V8?
While Jaguar has issued recalls and service bulletins for brake light switches on other models and years, searches of the NHTSA database and technical bulletins did not show any specific recalls for the 2005-2009 Jaguar Super V8 (X350/X358 chassis).
Why can't I shift out of Park? Is it my transmission?
Before assuming a costly transmission problem, always consider the brake light switch. It is a very common cause for the gear selector being locked in Park. The switch fails to send the necessary signal to the shift interlock solenoid, which is a safety feature.
Is a special tool needed for replacement?
Generally, no special tools are required. Basic hand tools like a socket and ratchet may be needed if the switch is held on with nuts. Some replacement switches are self-adjusting; they are installed while the brake pedal is held down and calibrate themselves when the pedal is released.
