The Rolls-Royce Silver Shadow uses H5001 bulbs for high beam headlights and H5006 bulbs for low beam headlights, with each size designed for specific lighting functions. The replacement chart covers vehicle production spanning 1966 to 1976, detailing bulb specifications across the model's manufacturing period.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Rolls-Royce Silver Shadow uses the H5001 sealed beam unit for high beam headlights across all model years from 1966-1976.
The H5001 is a 4-inch square sealed beam unit operating at 12V. It conforms to ANSI standards recognized in the United States and Canada. Because it is a sealed beam design, the entire unit is replaced rather than an internal filament or capsule.
Low beam headlights on the Silver Shadow use the H5006 sealed beam unit across the same 1966-1976 model year span.
The H5006 is a 5.75-inch round sealed beam unit, also rated at 12V and built to the same ANSI standard as the H5001. Like the H5001, the H5006 is replaced as a complete unit.
The H5001 and H5006 are physically distinct units. The square profile of the H5001 and the round profile of the H5006 make the two types non-interchangeable between the high beam and low beam positions.
Both sealed beam types were standardized formats widely used in North American automotive lighting during this period, meaning the Silver Shadow shares these bulb types with a broad range of other vehicles sold in the US and Canadian markets.
