What Lighting System Does the 1998 Jeep Wrangler Have?

The 1998 Jeep Wrangler features an extensive lighting system with 11 bulb positions. It uses halogen technology with a single H6024 LED dual-filament bulb handling both low and high beams. The Wrangler has been available from 1987 to 2019, and the 1998 model falls in the mid-generation years. As a Jeep vehicle, it uses a CANbus electrical system that monitors bulb status.

Can You Put LED Bulbs in a 1998 Jeep Wrangler?

Upgrading the 1998 Jeep Wrangler to LED headlights is straightforward since it uses a single H6024 LED dual-filament bulb for both low and high beams. You only need one pair of LED bulbs to upgrade both functions. Look for a H6024 LED LED kit that specifically supports dual-filament operation to ensure both beams work correctly. Important: Jeep vehicles use a CANbus system that detects bulb wattage. Standard LED bulbs may trigger dashboard warnings or flicker. Choose LED kits labeled "CANbus-compatible" or add inline decoder resistors to prevent these issues. For the fog lights, a H3 LED LED bulb provides a clean white output that pairs well with LED headlights.

How to Replace Bulbs on a 1998 Jeep Wrangler

To remove the headlight bulb, disconnect the wiring harness, then twist the bulb counter-clockwise and pull it straight out of the housing. Older model years like the 1998 Wrangler typically offer easy access to the headlight bulbs from behind the headlight assembly under the hood. Most owners can complete the swap in under 10 minutes per side. When installing the new bulb, avoid touching the glass with bare fingers. Skin oils create hot spots that shorten bulb life. Wear clean gloves or handle the bulb by its plastic base only. The fog lights are accessed from underneath the front bumper. You may need to remove a few plastic clips or screws from the fender liner to reach the H3 LED fog light socket.

How Long Do 1998 Jeep Wrangler Headlight Bulbs Last?

Standard halogen headlights on the 1998 Jeep Wrangler have an expected lifespan of 500 to 1,000 hours, which works out to roughly 2 to 3 years of normal use. Signs of a failing halogen bulb include noticeably dimmer output, a yellowish tint compared to the other headlight, or intermittent flickering. At 28 years old, the original bulbs on your Wrangler are likely overdue for replacement. Even if they still illuminate, reduced brightness significantly impacts nighttime safety. When one headlight burns out, replace both sides at the same time. Bulbs from the same batch age at similar rates, and mismatched brightness is distracting to oncoming drivers.

What Bulbs Are Compatible with the 1998 Jeep Wrangler?

The H6024 low beam bulb on the 1998 Jeep Wrangler is a specific fitment. There are no widely recognized cross-compatible alternatives, so make sure to purchase the exact H6024 size. Using the wrong bulb size can cause improper beam patterns that reduce your visibility and blind other drivers. It can also cause overheating inside the headlight housing, potentially warping the plastic lens or reflector. Always verify the bulb number before purchasing.

1998 Jeep Wrangler Headlight FAQ

The 1998 Jeep Wrangler uses a H6024 LED bulb for the low beam headlights. We recommend upgrading to LED for better visibility.

The high beam bulb size for the 1998 Jeep Wrangler is H6024 LED.

The 1998 Jeep Wrangler uses a single bulb (dual filament) headlight system. This means one bulb controls both high and low beams.

Yes, the 1998 Jeep Wrangler comes with standard halogen bulbs from the factory, but they can be upgraded to LED. You will need a H6024 LED LED conversion kit for the low beams.

Yes, the 1998 Jeep Wrangler takes a H3 LED bulb for the fog light position.

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 H6024 LED bulb counter-clockwise to remove it, then insert the new bulb and reassemble. Note: Jeep 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.

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 H6024 LED LED kit that is designed as a direct replacement and produces a proper cutoff pattern without excessive glare.

A pair of halogen H6024 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.

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 H6024 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.
