Dodge Daytona Headlight Bulb Size

Additional Notes

• The Dodge Daytona headlight specifications span the 1984-1993 model years, with the bulb types divided into two distinct generations: sealed beam units used from 1984 through 1991, and discrete halogen bulbs introduced for 1992 and 1993.
• The 9005 and 9006 bulbs, used in the 1992-1993 Dodge Daytona for high beam and low beam respectively, are single-filament halogen bulbs operating at 12V. The 9005 is rated at 65W with a P20d base, while the 9006 is rated at 55W with a P22d base. Despite their similar appearance, these two bulbs use different bases and are not interchangeable with each other.
• The H4666 sealed beam unit serves both the high beam and low beam positions in the 1987-1991 Daytona. Because it is a sealed beam, the lens, reflector, and filament are fused into a single assembly, meaning the entire unit is replaced rather than an individual bulb.
• The 1984-1986 Daytona uses separate sealed beam units for high and low beam functions: the H4651 for high beam and the H4652 for low beam. Both are 4x6-inch rectangular sealed beam units operating at 12V, with the H4652 classified as a variant of the H4651.
• Because the H4651 and H4652 are distinct sealed beam variants assigned to different beam functions, they are not interchangeable with each other despite sharing the same physical form factor.
• All bulb and sealed beam types listed across the full 1984-1993 Daytona range conform to ANSI standards applicable in both the United States and Canada.
• The transition from sealed beam units to discrete halogen bulbs between the 1991 and 1992 model years represents a change in headlight architecture. Sealed beam units require full assembly replacement, whereas the 9005 and 9006 halogen bulbs used from 1992 onward allow individual bulb replacement without disturbing the headlight housing.
