What Lighting System Does the 1989 Alfa-Romeo Spider Graduate Have?
The 1989 Alfa-Romeo Spider Graduate utilizes a refined lighting configuration featuring 13 distinct bulb positions. 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.
Can You Put LED Bulbs in a 1989 Alfa-Romeo Spider Graduate?
Upgrading to LED is one of the most effective ways to modernize your Alfa-Romeo's appearance and safety profile. Since your Spider Graduate 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 H2 LED fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
