1991 Honda Prelude bulb fitment uses H6054 sealed-beam bulbs for both the low-beam and high-beam headlights. The supplied fitment data does not identify separate projector or non-projector headlight configurations, so verify the original headlamp before ordering.

- Front and rear turn signals and reverse lights use 1156 bulbs.
- Brake and tail lights use 2057R bulbs, while the center stop light uses an 1156.
- Parking lights may use 168 or 917 bulbs, and both front and rear side markers use 168NA.
- The license plate light uses a 67 bulb.
- Interior applications include DE3175 for the dome light, DE3022 for the glove box, and DE3021 for the trunk light.
