How do I change the headlight on a 1991 Chrysler Imperial?

Turn off the vehicle and open the hood. Locate the headlight assembly from behind, remove the dust cover or retaining clip, disconnect the wiring harness, twist the old N/A bulb counter-clockwise to remove it, then insert the new bulb and reassemble. Note: Chrysler vehicles use a CANbus system, so LED replacements may need an anti-flicker decoder. The whole process typically takes 10 to 30 minutes per side depending on accessibility.

Are LED headlights legal for a 1991 Chrysler Imperial?

LED bulbs used off-road or in auxiliary lights are legal everywhere. For on-road headlight use, legality varies by state. Many states allow LED retrofits as long as the beam pattern meets DOT standards. For the best legal compliance, choose a DOT-approved N/A LED kit that is designed as a direct replacement and produces a proper cutoff pattern without excessive glare.

How much does it cost to replace 1991 Chrysler Imperial headlights?

A pair of halogen N/A bulbs costs $15 to $40, while LED conversion kits run $25 to $60 per pair. If you have a shop do the work, expect an additional $20 to $50 in labor per bulb. Replacing them yourself at home saves the labor cost and usually takes under 30 minutes.

What is the difference between halogen and LED for a 1991 Chrysler Imperial?

Halogen bulbs produce a warm yellow light (around 3200K), last 500 to 1000 hours, and draw more power. LED bulbs emit a brighter white light (5000-6000K), last 25,000+ hours, and use less energy. LED upgrades for the N/A position are available as direct plug-and-play replacements. Since the Chrysler uses CANbus monitoring, choose a CANbus-compatible LED kit to avoid dashboard errors.

Use a CANbus decoder.

Can You Put LED Bulbs in a 1991 Chrysler Imperial?

Upgrading to LED is one of the most effective ways to modernize your Chrysler's appearance and safety profile. We recommend starting your upgrade with the low beams, as they see the most use. Adding a matching 194 LED kit later will complete the look and ensure consistent lighting performance. Because Chrysler utilizes a CANbus system, standard LED bulbs may cause "bulb out" errors on your dashboard. Always opt for "Error-Free" or CANbus-ready kits which include the necessary resistors.
