1955-1956 Studebaker E14 Brake Light Switch Replacement Guide
Understanding the simple but critical brake light switch in your classic Studebaker truck.
- The E14 uses a hydraulic pressure switch located on the master cylinder or frame, not a mechanical one by the pedal.
- Failure is a critical safety issue; do not drive a vehicle with non-functioning brake lights.
- Replacement is a fast and easy DIY job for most owners, typically taking under 30 minutes.
- A new aftermarket switch from a reputable brand like Standard Ignition is the most reliable and cost-effective solution.
Is Your Studebaker's Brake Light Switch Failing?
A bad brake light switch on a classic truck like the E14 is a serious safety hazard. Since there are no dashboard warning lights for this system, you'll only discover a problem by physically checking the lights or when someone points it out. The symptoms are straightforward.
Key Failure Symptoms
- Brake Lights Do Not Turn On: This is the most dangerous symptom. If you've already checked that the bulbs and fuse are good, the switch is the most likely cause. The internal parts of the switch can fail, preventing it from sending power to the lights.
- Brake Lights Stay On: The switch can also fail in the 'on' position, causing the brake lights to remain lit even when you're not braking. This can confuse other drivers and will drain your battery when the truck is parked.
- Flickering or Delayed Brake Lights: An old or worn-out switch might make a poor connection, causing the lights to flicker or only come on after you press the brake pedal very hard. This is a sign of imminent failure.
Choosing the Right Aftermarket Switch
For a vehicle from the 1950s, original equipment (OEM) parts from Studebaker are no longer in production. Your main option is a new aftermarket part. New Old Stock (NOS) parts are extremely rare and can be unreliable after decades in storage. Fortunately, modern aftermarket switches are both affordable and dependable.
Brand Spotlight: Standard Ignition
Standard Ignition (also known as Standard Motor Products) is a well-regarded brand that has been trusted by mechanics for many years. Their replacement switches are manufactured to meet or exceed original specifications, often using modern materials for better durability and a longer service life. For a classic truck, a new switch from a quality manufacturer like Standard is the most practical and reliable choice.
Pro Tip: Quick Installation
When replacing this hydraulic switch, have the new part in your hand and ready to go before you fully unscrew the old one. Swap them quickly to minimize the amount of brake fluid you lose. This can help you avoid the need to bleed the brakes afterward.

Frequently Asked Questions
Where is the brake light switch located on my Studebaker E14?
The brake light switch is not inside the cab. Look for a small, two-wire switch screwed directly into the brake master cylinder or a junction block on the truck's frame where brake lines meet.
How can I test the brake light switch?
After confirming the bulbs and fuse are good, locate the switch. Unplug the two wires connected to it. Use a small jumper wire to connect the two terminals of the wiring harness plug together. If the brake lights turn on, the switch is bad and needs to be replaced. If they do not light up, you have a wiring or power supply issue elsewhere.
Is this a difficult part to replace myself?
No, this is a very easy job for most DIY mechanics. It requires basic hand tools to unscrew the old switch and screw in the new one. The entire process usually takes less than 30 minutes. Just be prepared for a small amount of brake fluid to drip out.
Are there any recalls for the Studebaker E14 brake light switch?
No recalls or Technical Service Bulletins (TSBs) from the NHTSA were found related to the brake light switch for this vehicle. This is normal for vehicles of this era.
