Common Headlight Switch Problems in the Chrysler Imperial
If you're experiencing issues with your 1976-1993 Chrysler Imperial's lighting, the headlight switch is a common culprit. Due to the electrical load it carries, the switch can degrade over time, leading to a variety of symptoms.
Signs of a Failing Headlight Switch
- Flickering Headlights: This is one of the most common symptoms. Headlights that flicker or turn off and on by themselves often point to a failing internal circuit breaker in the switch or dirty contacts.
- Headlights Don't Turn On: If your headlights, taillights, or dashboard lights don't turn on at all, the switch may have failed completely.
- Melted Connector: In some cases, the electrical connector on the back of the switch can overheat and melt. This indicates a serious electrical problem that needs immediate attention.
- Dashboard Lights Not Working: The dial that controls the brightness of your dashboard lights is part of the headlight switch. If these lights are not working or cannot be adjusted, the rheostat in the switch has likely failed.
Choosing the Right Aftermarket Headlight Switch
Since original Mopar parts for this era of Imperial are becoming scarce, the aftermarket is the go-to for most owners. Here's a look at the available brands:
- Standard Ignition (Standard Motor Products): Often considered a top-tier aftermarket brand, Standard Ignition parts are known for their quality and reliability. They often feature copper alloy conductors for better conductivity and are rigorously tested.
- Crown Automotive: Crown Automotive specializes in replacement parts for Chrysler, Dodge, and Jeep vehicles. They offer a wide range of parts and have been in business since 1963, suggesting a long-standing presence in the market.
- Rostra Powertrain: Rostra is a manufacturer of a wide variety of automotive components, including switches. They supply parts to both the OEM and aftermarket sectors.
Pro Tip: When replacing your headlight switch, it's a good idea to inspect the wiring and connector. If there are any signs of melting or corrosion, the connector should be replaced as well to prevent future failures.

Frequently Asked Questions
Can I still drive my Imperial with a faulty headlight switch?
If your headlights are not working at all, it is not safe or legal to drive your vehicle at night or in low-light conditions. If the lights are only flickering, it is still a significant safety risk and should be addressed immediately.
Why do my headlights flicker?
Flickering is often caused by the internal circuit breaker in the headlight switch tripping and resetting due to an overload or a short in the system. It can also be caused by dirty or worn contacts within the switch itself.
Is it difficult to replace the headlight switch myself?
For someone with basic mechanical skills, replacing the headlight switch is a feasible DIY project. It mainly involves removing some interior panels to gain access.
Should I buy an OEM or aftermarket headlight switch?
While OEM parts are always a good choice, they can be difficult to find for a vehicle of this age. High-quality aftermarket brands like Standard Ignition offer a reliable and more readily available alternative.
