Dodge Grand Caravan Headlight Bulb Size

Additional Notes

• The H11 bulb is the most widely used headlight bulb across the Dodge Grand Caravan's specification range, covering both high and low beam positions for the 2011-2019 model years. It is a single-filament halogen bulb rated at 12V and 55W, built to the ECE standard with a PGJ19-2 base, and is also approved for use in the United States.
• The 9007 and 9008 bulbs are dual-filament halogen types, meaning a single bulb serves both the high and low beam functions within one housing. The 9007, used on the Grand Caravan from 1996-2007, operates at 65W for high beam and 55W for low beam. The 9008, used from 2008-2010, shares the same wattage ratings but uses a different base type, the P26t, compared to the 9007's PX29t base, making the two types non-interchangeable despite their similar output ratings.
• The 9004 bulb, specified for 1989-1995 model years, is also a dual-filament ANSI-standard halogen type but runs at a lower wattage than the 9007 and 9008, rated at 65W for high beam and 45W for low beam. Its base type is P29t, which is distinct from both the 9007 and 9008 bases.
• For the 1987 and 1988 model years, the Dodge Grand Caravan was available with either halogen capsule headlamps or sealed beam headlamps, and the correct bulb type depends entirely on which headlamp system the vehicle was built with. These two configurations are not interchangeable.
• The H6054, specified for 1988 vehicles with sealed beam headlamps, is a 5x7-inch rectangular sealed beam unit. Unlike the replaceable bulbs used in other model years, the entire sealed beam unit is replaced as a single assembly rather than swapping an internal bulb.
• The 1987 model year with sealed beam headlamps uses different sealed beam types for the high and low beam positions. The high beam position takes the H4651, while the low beam position takes the H4656. Both are 4x6-inch rectangular sealed beam units operating at 12V, but they are separate part numbers and are not interchangeable with each other.
• Because the high and low beam specifications are identical across all model years in these data, the Grand Caravan does not use separate bulb types for each beam function in any year that employs a replaceable halogen capsule bulb. The dual-filament design of the 9004, 9007, and 9008 types handles both functions within a single unit, while the H11 years use the same single-filament bulb in both positions.
• The base types across the halogen capsule bulbs used on the Grand Caravan, specifically P29t for the 9004, PX29t for the 9007, P26t for the 9008, and PGJ19-2 for the H11, are each physically distinct. A bulb from one generation of the Grand Caravan's headlight specification will not fit the socket of another generation.
