Lighting on the 1988 Mitsubishi Tredia is managed by a total of 12 bulbs, covering everything from primary headlights to signal indicators. It features an extensive lighting system powered by a halogen-based setup where a single 9004 LED dual-filament bulb handles both low and high beam duties within the same reflector. This model belongs to the late years of the Tredia's 1983-1988 production span.

Can You Put LED Bulbs in a 1988 Mitsubishi Tredia?

Upgrading to LED is one of the most effective ways to modernize your Mitsubishi's appearance and safety profile. Since your Tredia uses a single 9004 LED bulb for both high and low beams, ensure your chosen LED kit is "dual-beam" compatible. This allows the LED circuitry to mimic the two-filament design of the original halogen bulb. Don't forget the LED Fog Light fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
