Brake Light Switch Guide for the 1962 Studebaker 7E13D
Fixing the brake lights on your classic Studebaker truck is a critical safety repair.
- The 1962 7E13D uses a hydraulic pressure switch on the master cylinder, not a mechanical switch at the pedal.
- The most common symptom of failure is the brake lights not working at all, which is a critical safety hazard.
- A new aftermarket switch from a brand like Standard Ignition is the most practical and reliable direct-fit replacement.
- Replacement is a simple DIY task, but you must bleed the brakes afterward to ensure safety.
Is Your Studebaker's Brake Light Switch Failing?
The brake light switch is a vital safety part on your classic truck. On these older vehicles, the switch is a simple hydraulic component that is part of the brake line system. Over time, the internal parts can wear out or fail, leading to dangerous brake light problems. Because it is activated by fluid pressure, its performance is directly linked to the health of your hydraulic brake system.
Choosing the Right Aftermarket Switch
For a vintage vehicle like a 1962 Studebaker, finding new original equipment (OEM) parts is not a realistic option. The most practical choice is a new aftermarket part from a trusted brand. Standard Ignition (also sold as SMP) is a well-known manufacturer that produces high-quality replacement parts that are designed to fit and function like the original. These switches are generally considered a reliable and readily available solution for keeping your classic truck safe.
Some classic car owners have noted that modern reproduction hydraulic switches can sometimes fail prematurely. This can occasionally be linked to using modern DOT 5 silicone brake fluid, which some switches are not compatible with. The Standard Ignition switch is designed for use with standard DOT 3 brake fluid, which was original to the vehicle.

Frequently Asked Questions (FAQ)
Where is the brake light switch located on my 1962 Studebaker 7E13D?
The brake light switch is not inside the cab by the pedal. It is a hydraulic pressure switch located in the engine bay, screwed directly into the master cylinder or a nearby brake line junction block. It will have two electrical wires connected to it.
Is replacing the brake light switch a difficult DIY job?
For a DIY mechanic, this is a relatively easy job. It involves disconnecting the two wires, unscrewing the old switch, and quickly screwing in the new one to minimize brake fluid loss. However, it is critical that you bleed the brakes after replacement to remove any air that entered the system. If you are not familiar with bleeding brakes, it is best to have a professional mechanic perform the repair.
How do I test my old brake light switch?
First, always check that your brake light bulbs and fuse are good. If they are, you can test the switch by locating it and unplugging the two wires. Carefully use a small jumper wire to connect the two wire terminals. If the brake lights turn on, the switch is bad and needs to be replaced. If they do not light up, the problem is somewhere else in the wiring.
Are there any recalls for the brake light switch on my Studebaker truck?
No, there are no official recalls or Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) for the brake light switch on a 1962 Studebaker. This is normal for a vehicle of this age.
Can I upgrade to a more reliable mechanical switch?
Yes, some Studebaker owners choose to convert to a modern mechanical brake light switch that mounts near the brake pedal. This modification provides more reliable light activation and removes a potential brake fluid leak point. However, this is a custom project that requires fabricating a bracket and rerouting wires. For a direct and simple repair, the new aftermarket hydraulic switch is the correct choice.
