Understanding Brake Light Switch Failure in Your LeBaron
A faulty brake light switch is a common issue on many vehicles, including the 1977-1984 Chrysler LeBaron. Due to its location and constant use, the internal contacts can wear out, or the plastic housing can become brittle and crack. The most obvious sign of failure is when your brake lights do not turn on at all when you press the pedal. Conversely, the switch can fail in the 'on' position, causing the brake lights to stay on continuously, which can drain your battery. You might also notice intermittent or flickering brake lights.
Critical Safety Warning
Driving with a non-functional brake light switch is extremely dangerous and illegal. It significantly increases the risk of a rear-end collision. If you suspect your brake light switch has failed, you should not drive the vehicle until it is repaired.
Choosing the Right Aftermarket Brake Light Switch
For a classic vehicle like the 1977-1984 LeBaron, aftermarket parts are the most common and accessible option. Original Equipment Manufacturer (OEM) parts are likely discontinued and hard to find. Fortunately, the brake light switch is a straightforward part, and reputable aftermarket brands offer reliable replacements.
- Standard Ignition (Standard Motor Products): This is a well-regarded brand in the aftermarket industry with a long history. Their products are generally known for being a dependable, good-quality replacement for the original part. Customer reviews for similar switches are positive, often citing a perfect fit and easy installation.
- Skyward: This brand is typically positioned as a budget-friendly option. While there is less specific information available about the quality of their brake light switches, they can be a viable choice if cost is the primary concern. For a simple component like this, even a value-brand part is a significant safety improvement over a non-functional one.
Pro Tip: When replacing the switch, it's also a good time to inspect the brake light bulbs and fuses. A faulty switch is a common culprit, but sometimes the issue can be as simple as a burnt-out bulb or a blown fuse.
