1962 Studebaker 7E10 Brake Light Switch Replacement and Diagnosis
Keep your classic Studebaker truck safe and visible with a functioning brake light switch.
- The 1962 Studebaker 7E10 uses a hydraulic pressure switch, not a mechanical one at the pedal.
- Failure is common and presents a critical safety risk. The most frequent symptom is the brake lights not working at all.
- A new aftermarket switch from a reputable brand like Standard Ignition is the most practical replacement option.
- Replacement is a straightforward DIY task, but bleeding the brakes afterward is mandatory to ensure safe brake operation.
Is Your Brake Light Switch Failing?
A faulty brake light switch is a common issue on classic vehicles like the Studebaker 7E10. The original-style hydraulic switches are known to have reliability problems and can be a source of brake fluid leaks. Before you assume the switch is bad, always check the simplest things first: make sure the brake light bulbs are good and check the fuse for the brake light circuit.
Symptoms of a Bad Brake Light Switch:
🎬 Watch this guide on identifying and fixing common switch symptoms.- Brake Lights Don't Work: This is the most common and dangerous symptom. The switch fails to complete the circuit when you press the brakes.
- Brake Lights Stay On: Less common, but the switch can fail in the 'on' position, causing your brake lights to remain lit even when you're not braking. This will drain your battery.
- Intermittent Brake Lights: The lights may flicker or only work when you press the pedal very hard. This indicates the switch is failing internally.
A Note on Brake Fluid
Some owners report that modern DOT 5 silicone brake fluid can cause premature failure in reproduction hydraulic switches. The Standard Ignition switch is designed for use with standard DOT 3 brake fluid, which was original to the vehicle. Always verify fluid compatibility before installation.
Choosing Your Aftermarket Replacement
For a 1962 Studebaker, finding New Old Stock (NOS) OEM parts is rare and often expensive. The most practical and reliable solution is a new aftermarket switch.
Standard Ignition (Standard Motor Products): This is a well-established brand known for producing quality replacement parts for domestic and import vehicles, including classics. Their switches are designed to meet or exceed original specifications and are a trusted choice for a direct-fit replacement. Reviews from classic car owners are generally positive, citing good fit and function.
Pro Tip: Consider an Upgrade
For added reliability, some Studebaker owners convert to a modern mechanical brake light switch that mounts near the brake pedal. This modification eliminates the hydraulic switch, providing more consistent activation and removing a potential leak point. However, this is a custom job that requires fabricating brackets and modifying wiring.

Frequently Asked Questions (FAQ)
Where is the brake light switch located on my 1962 Studebaker 7E10?
The brake light switch is not inside the cab. It is a hydraulic pressure switch located under the hood, screwed into the master cylinder or a brake line junction block on the frame. It will have two electrical wires connected to it.
How can I test my brake light switch?
After confirming the bulbs and fuse are good, you can test the switch. Locate it and unplug the two wires. Use a small jumper wire to carefully connect the two wire terminals together. If the brake lights turn on, the switch is faulty and needs replacement. If they do not light up, the problem is elsewhere in the wiring.
Is it difficult to replace the brake light switch myself?
For a DIYer, this is a fairly easy job. It involves unplugging the wires, unscrewing the old switch, and screwing in the new one. The key is to be ready with the new switch to install it quickly to minimize brake fluid loss. However, you must bleed the brakes after replacement to remove any air that entered the system.
Are there any recalls for the brake light switch on my Studebaker?
There are no open recalls on file with the National Highway Traffic Safety Administration (NHTSA) for the 1962 Studebaker 7E10. Due to the vehicle's age, official recalls from this era are not typically in modern databases.
