LED bulbs used off-road or in auxiliary lights are legal everywhere. For on-road headlight use, legality varies by state.

A pair of halogen H6054 LED 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 1990 Jeep Comanche?

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 H6054 LED position are available as direct plug-and-play replacements. Since the Jeep uses CANbus monitoring, choose a CANbus-compatible LED kit to avoid dashboard errors.

LED Flicker Warning

This vehicle is known to use a CANbus system. Installing standard LEDs may cause flickering.

Use a CANbus decoder.

Can You Put LED Bulbs in a 1990 Jeep Comanche?

For a Jeep built for the road and trail, LED upgrades provide the high-contrast lighting needed for better obstacle detection. We recommend starting your upgrade with the H6054 LED 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 Jeep 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. Don't forget the LED Fog Light fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
