Is Your Eagle Summit Brake Light Switch Failing?
A faulty brake light switch on an older vehicle like the Eagle Summit can cause several obvious and frustrating electrical problems. Because the switch is a simple mechanical part that gets used every time you drive, it's common for it to wear out. Over time, the internal contacts can burn out or the plastic plunger can break. Recognizing the signs of failure is the first step to a quick repair.
Common Symptoms of a Bad Switch
If your brake light switch is going bad, you'll likely experience one or more of these issues:
- Brake Lights Don't Work: This is the most dangerous symptom. The switch fails to complete the electrical circuit, and your brake lights will not turn on at all.
- Brake Lights Stay On: The switch can get stuck in the 'on' position, causing the brake lights to remain lit even when your foot is off the pedal. This will drain your battery and confuse other drivers.
- Can't Shift Out of Park: The safety interlock won't receive the signal that the brake is applied, leaving your gear shifter locked in Park.
- Cruise Control Issues: If you have cruise control, it may not engage, or it might shut off unexpectedly because it's getting a false signal from the failing switch.
Safety First: Driving Without Brake Lights
It is extremely dangerous to drive your vehicle if the brake lights are not working. Other drivers will have no warning when you are slowing or stopping, which can easily cause a rear-end collision. If you confirm your brake lights are out, do not drive the vehicle until it is repaired.
Choosing the Right Aftermarket Brake Light Switch
For a vehicle like the 1989-1996 Eagle Summit, an aftermarket brake light switch is a smart and budget-friendly choice. Original OEM parts, if you can even find them, offer no significant advantage for a simple component like this. The key is to choose a brand with a reputation for quality control.
Here’s a breakdown of the available brand tiers:
- Good (Tier 1): Brands like Standard Ignition (SMP) and Rostra Powertrain are well-regarded in the aftermarket industry. Rostra is an ISO-certified OE supplier for some manufacturers, and their parts are known for quality. Standard Ignition is a long-standing brand with a solid reputation for reliable electronic components.
- Standard (Tier 2): Facet is an Italian brand with a long history that produces a massive catalog of parts. They are generally considered a reliable, standard-grade replacement option that meets or exceeds original specifications.
- Economy (Tier 3): The Replacement brand is a generic or house brand. While it's the most affordable option, quality can be inconsistent. For a critical safety part like a brake light switch, spending a few extra dollars for a Tier 1 or 2 brand is a wise investment.
Pro Tip: The Eagle Summit was a rebadged version of the Mitsubishi Mirage and Colt. Don't be surprised if the part you order is also listed for these Mitsubishi models, as they are often identical.

Frequently Asked Questions (FAQ)
Can I replace the Eagle Summit brake light switch myself?
Yes, absolutely. This is a very easy DIY job that takes less than 30 minutes. The switch is located just above the brake pedal arm. You simply disconnect the electrical plug, then twist and pull the old switch out of its bracket. Install the new one in reverse order and test your lights.
Are there any recalls for the Eagle Summit brake light switch?
No. A search of the National Highway Traffic Safety Administration (NHTSA) database shows no specific safety recalls or technical service bulletins (TSBs) for the brake light switch on the 1989-1996 Eagle Summit.
Do I need to adjust the new brake light switch?
Most modern replacement switches are self-adjusting. When you install it, the plunger sets itself to the correct depth as the brake pedal returns to its resting position. Always test the brake lights after installation to make sure they turn on and off with just a light touch of the pedal.
My brake lights work, but my cruise control doesn't. Could it still be the switch?
Yes. The brake light switch for vehicles with cruise control often has two separate internal circuits inside one housing—one for the lights and one for the cruise control signal. It's common for the cruise control side to fail while the brake light side continues to work properly. Given the low cost of the part, it's an excellent first diagnostic step.
