Is Your Charger's Headlight Switch Failing?
The headlight switch in a classic Dodge Charger is a hard-working part. After 50 years, the internal components can wear out. The most common problem is with the internal thermal circuit breaker. Heat and age cause it to become weak. When it gets hot, it can trip unexpectedly, causing your headlights to suddenly turn off. After it cools for a few seconds or minutes, it resets, and the lights come back on. This cycle can be dangerous if it happens while you are driving at night.
Common Failure Symptoms
- Headlights flicker or turn off: The lights work for a while, then shut off and come back on by themselves.
- Lights won't turn on: Headlights, taillights, or dash lights do not work at all.
- Dash lights don't dim: The dimmer function stops working, leaving your dash lights stuck on one brightness or completely off.
- Buzzing sound: A buzzing or clicking noise comes from the switch when you turn the lights on.
- Blown fuses: A failing switch can cause a short that repeatedly blows the fuse for the lighting circuit. 🎬 Watch: How a bad switch causes flickering headlights.
Choosing the Right Aftermarket Headlight Switch
For a vehicle from the early 1970s, finding a "New Old Stock" (NOS) OEM part is very difficult and expensive. Used original parts are available, but they are just as old as the one you are replacing. Modern aftermarket switches are the most practical and reliable choice. The quality of these parts can vary by brand.
Brand Quality Tiers
- Standard Ignition (Standard Motor Products): Often considered a premium aftermarket brand. They are known for using quality materials like copper alloy conductors and for extensive testing to ensure performance. For many mechanics and restorers, Standard is a trusted name for electrical parts.
- Crown Automotive: Crown is a well-known supplier of parts for Chrysler vehicles, especially Jeeps. They offer a wide range of replacement parts that generally provide a good balance of quality and affordability. Reviews for their switches on similar classic vehicles are often positive, citing good fit and function.
- Replacement: This category typically includes various house brands or unbranded parts. They are the most budget-friendly option. While they will function, the long-term durability and quality of internal components may not match that of more established brands.

Frequently Asked Questions (FAQ)
Is it hard to replace the headlight switch myself?
No, it is a relatively easy job for someone with basic tools. You do not need to remove the entire dashboard. The process involves disconnecting the battery, pressing a small button on the switch to release the knob, unscrewing a retaining nut, and unplugging the wiring harness. Total time is usually under an hour.

Searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any recalls specifically for the headlight switch on 1971-1975 Dodge Charger models.
My headlights turn off by themselves. Is it the switch or a short?
While it could be a short, the most common cause of this symptom in these cars is the headlight switch itself. The internal circuit breaker becomes weak with age and trips when it gets hot, causing the lights to cycle on and off. Replacing the switch usually solves the problem.
My Charger has hideaway headlights. Is the switch different?
The main headlight switch is the same. However, cars with the hideaway headlight option have an additional relay system that controls the motors for the headlight doors. While a faulty switch can cause the lights not to turn on, problems with the doors opening or closing are usually related to the separate hideaway relay or motor.
