1984-1987 Honda Wagovan Brake Light Switch: A Complete Guide
Everything Wagovan owners need to know about diagnosing and replacing a faulty brake light switch.
- Before replacing the switch, check for broken plastic pieces on your floor mat; a failed pedal stopper pad is the most common cause of brake lights staying on.
- This is a critical safety part. If your brake lights do not work, the vehicle is not safe to drive.
- Replacement is very easy and can be done in under 30 minutes with basic tools, making it a great DIY task.
- A quality aftermarket switch from a brand like Standard Ignition or Rostra is a reliable and cost-effective choice for this vehicle.
Is Your Wagovan's Brake Light Switch Failing?
A bad brake light switch on an older Honda like the Wagovan will show clear symptoms. Since this part is vital for safety, you must recognize the signs of failure and act quickly. Driving with faulty brake lights is illegal and significantly increases your risk of a rear-end collision.
Key Symptoms of a Bad Switch:
- Brake Lights Don't Turn On: This is the most dangerous symptom. The switch has failed and is not completing the circuit to illuminate the lights.
- Brake Lights Stay On: The switch can get stuck in the 'on' position, leaving your brake lights constantly lit. This can drain your battery and confuse other drivers.
- Intermittent Brake Lights: If the lights flicker or only work sometimes, the switch is likely worn out and about to fail completely.
Check This First: The Pedal Stopper Pad
On many older Hondas, the most common reason for brake lights staying on is NOT the switch itself. A small plastic disc called a pedal stopper pad, located on the brake pedal arm, becomes brittle and crumbles over time. When it breaks, the switch's plunger goes right through the hole where the pad used to be, causing the switch to remain activated. Look for small, broken pieces of plastic on your driver-side floor mat. If you see them, and there's a hole in the pedal arm where it meets the switch, you just need a new stopper pad (Honda Part No. 46505-SA5-000), not a whole new switch.
Choosing the Right Aftermarket Brake Light Switch
For a straightforward part like a brake light switch on a 1984-1987 Wagovan, there is no significant functional difference between an OEM part and a quality aftermarket one. Aftermarket switches are readily available, affordable, and reliable for this application. The key is to choose a reputable brand.
Available Brand Tiers:
- Standard Ignition: Often considered a top-tier aftermarket brand, Standard Ignition (also known as SMP) parts are known for their quality and reliability, often meeting or exceeding original specifications. They are a trusted choice for professional technicians.
- Rostra Powertrain: Rostra is a well-regarded manufacturer of various automotive electronic components, including sensors and switches. They are known for producing quality parts and are an OE manufacturer for some brands, indicating a high level of quality control.
- Replacement: This brand offers a budget-friendly option. While it will function correctly, it may not have the same long-term durability or material quality as higher-tiered brands like Standard or Rostra.
Pro Tip: Before replacing the switch, always check the fuse for the brake lights (often shared with the horn) and the bulbs themselves to rule out simpler problems.

Frequently Asked Questions
Where is the brake light switch located on my Wagovan?
The brake light switch is mounted on a bracket under the dashboard, directly above the brake pedal arm. You will need to look up from the driver's side floor to see it.
Can I replace the brake light switch myself?
Yes, this is a very easy job for a DIY mechanic. It typically requires only a basic wrench (often 14mm) to loosen the locknut. The most difficult part is usually the uncomfortable position of working in the driver's footwell. The process involves unplugging the electrical connector, unscrewing the old switch, screwing in the new one, and adjusting it.
How do I adjust the new brake light switch?
The switch is threaded like a bolt. After installing it, you must screw it in or out until its plunger is fully depressed when the brake pedal is at rest. The lights should come on as soon as the pedal is pressed slightly. Once adjusted, tighten the locknut to hold it in place. Proper adjustment is critical for the switch to work correctly.
Are there any recalls for the brake light switch on the 1984-1987 Wagovan?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any specific recalls for the brake light switch on the 1984-1987 Honda Civic Wagovan.
