Common Symptoms of a Failing Headlight Switch
When a headlight switch starts to fail in an older car like the Dodge Colt, the signs are usually noticeable. Due to age, the internal contacts can corrode or wear out, leading to a variety of electrical problems. Here’s what to look for:
- Flickering or Intermittent Headlights: Your headlights may flash on and off by themselves while you're driving. This is often caused by an internal circuit breaker in the switch overheating from high resistance and repeatedly resetting itself.
- Lights Only Work on Certain Settings: You might find that your high beams work but your low beams don't, or that the parking lights won't turn on. This points to a failure of specific contacts inside the switch.
- Dashboard Lights Malfunction: If you can no longer dim your instrument panel lights or they don't turn on at all with the headlights, the rheostat part of the switch has likely failed.
- Switch is Hot to the Touch: A switch that feels unusually hot or emits a burning plastic smell is a serious warning sign. This indicates a short circuit or severe electrical resistance inside, which is a fire hazard.
- Total Failure: The most obvious symptom is when none of your lights turn on. After confirming the bulbs and fuses are good, the switch becomes the primary suspect.
Safety First
Driving with malfunctioning headlights is a critical safety risk and illegal in all states. If your headlights are not working reliably, you should not drive the vehicle at night until the issue is repaired.
Choosing the Right Aftermarket Headlight Switch
For a vehicle from the late '70s and early '80s, finding a brand-new Original Equipment Manufacturer (OEM) part is nearly impossible. The choice comes down to a used OEM part from a salvage yard or a new aftermarket part.
- Used OEM: This can be a cheap option, but you are buying a part that is just as old as the one that failed. It may not last long.
- New Aftermarket: This is the most practical and recommended solution. An aftermarket switch provides all-new components, ensuring reliability.
Brand Spotlight: Standard Ignition
Standard Motor Products (SMP), the manufacturer of Standard Ignition parts, is a well-established and respected brand in the aftermarket industry. Their products are designed to meet or exceed original specifications. For classic cars where OEM parts are scarce, Standard is often considered a go-to for reliable electrical components like ignition and headlight switches. A new Standard switch ensures fresh internal contacts, a new circuit breaker, and a functional rheostat for your dash lights.
Headlight Switch Replacement Cost
Replacing the headlight switch on a 1979-1983 Dodge Colt is an affordable repair. The primary cost is the part itself, with labor being minimal if you do it yourself.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket (Standard Ignition) | $42.98 |
| Shop Labor | $50 - $100 |
| Total Estimated Cost (Installed) | $93 - $143 |
DIY Pro Tip
Replacement is straightforward for those with basic tools. The process generally involves disconnecting the battery, reaching under the dashboard to press a release button on the switch body, which allows the knob and shaft to pull out from the front. Then, a special nut holding the switch to the dash can be unscrewed, the switch lowered, and the electrical connector unplugged. Installation is the reverse of removal.
Frequently Asked Questions (FAQ)
Can I still drive my Dodge Colt with a bad headlight switch?
If your headlights are flickering or do not turn on at all, it is unsafe and illegal to drive at night or in poor visibility conditions. If the issue only affects your dashboard lights, you can drive, but you should get it fixed promptly for safety.
Are there any recalls for the 1979-1983 Dodge Colt headlight switch?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls specifically related to the headlight switch for the 1979-1983 Dodge Colt.
Why do my headlights turn off and on by themselves?
This is a classic symptom of a failing headlight switch in older cars. The switch contains an internal thermal circuit breaker. When the switch's contacts become corroded, they create high resistance and heat, causing the breaker to trip and cut power to the lights. As it cools, it resets, and the lights come back on, creating a dangerous cycle.
Is it better to clean my original switch or buy a new one?
While some classic car hobbyists disassemble and clean original switches, this is a delicate process that may not solve the problem if components are too worn. For a daily driver or a reliable repair, a new aftermarket switch is the recommended choice as it replaces all potential failure points at once.
