Additional Notes

The Eagle Summit uses the 9005 bulb for high beam headlights across the 1989-1992 model years, and the 9006 bulb for low beam headlights across the same span.
Both the 9005 and 9006 are ANSI-standardized halogen bulbs recognized in the United States and Canada, each containing a single filament.
The 9005 operates at 12 volts and 65 watts, while the 9006 operates at 12 volts but draws less power at 55 watts.
Although the 9005 and 9006 share the same voltage rating, their base types differ: the 9005 uses a P20d base and the 9006 uses a P22d base, making the two bulbs physically non-interchangeable.
The differing base types between the 9005 and 9006 serve as a mechanical safeguard, preventing a high beam bulb from being seated in a low beam socket and vice versa.
Single-filament construction means each bulb in the Eagle Summit's headlight system handles only one lighting function, requiring separate bulbs for high and low beam operation rather than a dual-filament unit.
