Symptoms of a Failing Brake Light Switch
A bad brake light switch can be a major safety problem. Since the 1966 Wagonaire is a classic vehicle, its wiring is simple, making diagnosis straightforward. Here are the most common signs of failure:
- Brake Lights Do Not Turn On: This is the most dangerous symptom. The switch fails to complete the circuit when you press the brake pedal.
- Brake Lights Stay On: The switch can get stuck in the 'on' position, leaving the brake lights permanently lit. This will drain your battery and confuse drivers behind you.
- Flickering or Intermittent Lights: The internal contacts of the switch can wear out, causing the brake lights to flicker when you press the pedal or drive over bumps.
Safety First
Driving without working brake lights is illegal and extremely dangerous. If you suspect your brake light switch has failed, you should not drive the vehicle until it is repaired.
Choosing the Right Aftermarket Switch
For a classic vehicle like the 1966 Wagonaire, finding New Old Stock (NOS) OEM parts is nearly impossible and very expensive. Aftermarket parts are the most practical and common solution. The good news is that the brake light switch is a fairly universal part for cars of this era, and reputable aftermarket brands produce reliable replacements.
Brand Options: Standard Ignition vs. Rostra Powertrain
- Standard Ignition (Standard Motor Products): Standard is a well-respected brand that has been making quality automotive electrical parts for over 100 years. Their switches are known for durability and are often considered a go-to choice for professional mechanics and restorers. They use copper alloy conductors and robust materials to ensure a long service life.
- Rostra Powertrain: Rostra is another established manufacturer of vehicle electronics for both OEM and aftermarket applications. They produce direct-fit replacement parts that are 100% tested to meet or exceed original specifications, ensuring reliable performance.
Pro Tip: Both Standard Ignition and Rostra are solid choices for your Wagonaire. The decision often comes down to availability and slight price differences. You can be confident installing a switch from either of these established brands.
