Guide to the 1962 Studebaker 7E7 Brake Light Switch
Keep your classic Studebaker truck safe and on the road by understanding its unique brake light switch.
- The 1962 7E7 uses a hydraulic pressure switch, not a mechanical one by the pedal.
- A failing switch is a critical safety issue; do not drive if your brake lights are not working correctly.
- Replacement is a feasible DIY job but requires bleeding the brakes, which is a crucial step for safety.
- New aftermarket switches from brands like Standard Ignition are the most practical and available replacement option.
Is Your Studebaker's Brake Light Switch Failing?
A bad brake light switch on your 1962 7E7 Champ truck creates immediate and serious safety hazards. Since there are no dashboard warning lights for this system, you'll only know there's a problem by physically checking the lights or if someone points it out. The symptoms are very clear.
Key Failure Symptoms:
- Brake Lights Do Not Turn On: This is the most common and dangerous symptom. The switch has failed internally and no longer closes the circuit when you press the brake pedal. This is a critical failure that puts you at high risk of a rear-end collision.
- Brake Lights Stay On: The switch can also fail by getting stuck in the 'on' position. This will keep your brake lights illuminated at all times, which can confuse other drivers and will drain your battery when the truck is parked.
- Lights Only Work Under Hard Braking: As the switch wears out, it may require more hydraulic pressure to activate. If your brake lights only come on during a hard stop, the switch is failing and needs to be replaced immediately.
Choosing the Right Aftermarket Switch
For a classic vehicle like the 1962 Studebaker 7E7, original equipment (OEM) switches from Studebaker are no longer in production. Your primary option is a new aftermarket part.
New Aftermarket: This is the most practical and common choice. Brands like Standard Ignition produce replacement hydraulic switches (such as part number SLS27) that are designed to fit and function like the original. These parts are readily available and affordable. For a simple but critical part like a hydraulic brake switch, a quality aftermarket replacement is a reliable choice.
Pro Tip: Some classic car owners report that the quality of reproduction hydraulic switches can be inconsistent. It's a good idea to test the part before installation if possible. Many dedicated Studebaker owners eventually choose to modify their trucks to use a more reliable modern mechanical switch near the brake pedal, though this requires custom fabrication.
Typical Replacement Costs for a 1962 Studebaker 7E7
| Part Type | Estimated Cost |
|---|---|
| New OEM | Not Available |
| New Aftermarket (Standard Ignition) | $15 - $20 |
| Used OEM (Swap Meet/NOS) | Varies |

Cost estimates are approximate and can vary. Labor costs can be higher at shops specializing in classic vehicles. The job requires bleeding the brakes, which adds time.
Frequently Asked Questions (FAQ)
Where is the brake light switch located on a 1962 Studebaker 7E7?
The brake light switch is not inside the cab by the pedal. It is a hydraulic switch screwed into the master cylinder or a T-fitting in the brake lines, usually found in the engine bay or along the frame rail. It will have two wires connected to it.
Do I need to bleed the brakes after replacing this switch?
Yes. Because the switch is part of the hydraulic brake system, replacing it will introduce air into the lines. You absolutely must bleed the brakes after installing the new switch to ensure your brakes work safely and effectively. Failure to do so is extremely dangerous.
Is replacing the brake light switch a DIY job?
Yes, if you are comfortable working on hydraulic brake systems. The job involves carefully unscrewing the old switch, installing the new one, and bleeding the brakes. You will need flare nut wrenches to avoid damaging the brake line fittings. If you are not familiar with bleeding brakes, it is best to have a professional mechanic perform the replacement.
Are there any recalls for the 1962 Studebaker 7E7 brake light switch?
No. There are no official recalls or technical service bulletins (TSBs) from the NHTSA for this part on a 1962 Studebaker. Recalls for vehicles of this age are extremely rare.
