What Lighting System Does the 1987 Porsche 928 Have?
The 1987 Porsche 928 features an extensive lighting system with 11 bulb positions. It uses halogen technology with a single 9004 LED dual-filament bulb handling both low and high beams. The 928 has been available from 1981 to 1995, and the 1987 model falls in the mid-generation years.
Can You Put LED Bulbs in a 1987 Porsche 928?
Upgrading the 1987 Porsche 928 to LED headlights is straightforward since it uses a single 9004 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 9004 LED LED kit that specifically supports dual-filament operation to ensure both beams work correctly. For the fog lights, a H3 LED LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 1987 Porsche 928
To remove the headlight bulb, disconnect the wiring harness, then twist the bulb counter-clockwise and pull it straight out of the housing. Porsche 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 H3 LED fog light socket.

Standard halogen headlights on the 1987 Porsche 928 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 39 years old, the original bulbs on your 928 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.
