The 1991 Subaru XT utilizes a refined lighting configuration featuring 14 distinct bulb positions. It features an extensive lighting system powered by a halogen-based setup where a single 6052 LED dual-filament bulb handles both low and high beam duties within the same reflector. This model belongs to the late years of the XT's 1985-1991 production span.

Can You Put LED Bulbs in a 1991 Subaru XT?

Upgrading to LED is one of the most effective ways to modernize your Subaru's appearance and safety profile. Since your XT uses a single 6052 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.
