What Lighting System Does the 1997 Land Rover Defender 90 Have?

The 1997 Land Rover Defender 90 features a comprehensive lighting system with 10 bulb positions. It uses halogen technology with a single H6024 LED dual-filament bulb handling both low and high beams. The Defender 90 has been available from 1994 to 1997, and the 1997 model falls in the late-generation years.

Can You Put LED Bulbs in a 1997 Land Rover Defender 90?

Upgrading the 1997 Land Rover Defender 90 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. For the fog lights, a LED Fog Light LED bulb provides a clean white output that pairs well with LED headlights.

How to Replace Bulbs on a 1997 Land Rover Defender 90

To remove the headlight bulb, disconnect the wiring harness, then twist the bulb counter-clockwise and pull it straight out of the housing. Land Rover vehicles are known for tight engine bay clearances around the headlight assembly. You may need to remove the air intake duct, battery cover, or wheel well liner to access the bulbs. Budget 30 to 45 minutes per side for your first replacement. 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 LED Fog Light fog light socket.

How Long Do 1997 Land Rover Defender 90 Headlight Bulbs Last?

Standard halogen headlights on the 1997 Land Rover Defender 90 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 29 years old, the original bulbs on your Defender 90 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 1997 Land Rover Defender 90?

The H6024 low beam bulb on the 1997 Land Rover Defender 90 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.

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