Frequently Asked Questions

Our database lists 9006 for the 1990 Mitsubishi Sigma low beam headlights. Verify the bulb number on your existing bulb and confirm your trim or factory lighting package before buying.

Our database lists 9005 for the 1990 Mitsubishi Sigma high beam position. Some vehicles vary by trim, lighting package, or previous housing changes.

Dim headlights on a 1990 Mitsubishi Sigma can come from aging halogen bulbs, cloudy lenses, weak electrical connections, or an incorrect bulb. Confirm the listed 9006 size against the bulb in the housing before choosing a replacement or upgrade.

The 1990 Mitsubishi Sigma does not have a fog light bulb listed in our current database. If your vehicle has fog lights, verify the bulb in the housing or owner's manual before buying.

The 1990 Mitsubishi Sigma uses a dual bulb headlight system. This means you have separate bulbs for high and low beams.

LED upgrades are available for many 9006 applications, but fitment, beam pattern, dashboard warnings, and road-use legality can vary. Use products that list your exact bulb family, such as 9006 / HB4, and verify the factory housing before buying.

No — the 1990 Mitsubishi Sigma uses the same bulb sizes as the 1989 model. This configuration has been consistent across the 1989–1990 generation.

The 1990 Mitsubishi Sigma is the last year in the 1989–1990 generation to use the 9006 bulb for the low beam headlight.

Access varies by engine bay layout and headlight housing. Before disassembly, confirm the listed 9006 low beam size on the existing bulb or owner's manual, then follow the service procedure for your exact trim.

Rules for LED headlight retrofits vary by location and by housing type. Avoid products that create glare or lack road-use compliance claims, and check local requirements before using an LED conversion on public roads.

Replacement cost depends on bulb technology, brand, and labor access. Common halogen 9006 replacements are usually cheaper than LED conversion kits. Check seller fitment notes before comparing prices.

Halogen bulbs and LED replacements differ in output, heat behavior, beam pattern, and electronics. A correct bulb code does not guarantee a correct LED beam pattern, so verify physical fit and seller compatibility notes for the 1990 Mitsubishi Sigma.
