Chevrolet Camaro Headlight Bulb Size

Additional Notes

• The D3S is an ECE-standard, mercury-free HID xenon bulb rated at 42V and 35W with a PK32d-5 base and integral ignitor. It serves as both the high beam and low beam bulb in the Chevrolet Camaro (2016-2021) equipped with HID headlamps, meaning a single bulb type handles both functions within a projector-type housing.
• The D1S is an earlier ECE-standard HID xenon bulb rated at 85V and 35W with a PK32d-2 base and integral ignitor. The 2010-2013 Camaro with HID headlamps used the D1S for both high and low beam positions, and it is not interchangeable with the D3S despite sharing a similar wattage and projector-housing application.
• The 9008 is a dual-filament halogen bulb rated at 12V with separate filaments for high beam (65W) and low beam (55W). The 2010-2013 Camaro with halogen capsule headlamps used this single bulb to serve both beam functions, which distinguishes it from single-filament types that handle only one beam position.
• The H9 and H11 are both ECE-standard halogen bulbs approved for use in the US, but they are not interchangeable. The 2014-2015 Camaro with halogen headlamps used the H9 (65W, PGJ19-5 base) for high beam and the H11 (55W, PGJ19-2 base) for low beam, and the differing bases physically prevent cross-installation.
• The 9005 and 9006 are ANSI-standard single-filament halogen bulbs that share a similar appearance but have different base designs, making them non-interchangeable. The 1998-2002 Camaro used the 9005 (65W, P20d base) for high beam and the 9006 (55W, P22d base) for low beam.
• The H4352 and H4351 are 5.75-inch round sealed beam units used in the 1993-1997 Camaro. The H4352 served the high beam position and the H4351 served the low beam position. As sealed beam units, the entire assembly is replaced rather than an individual bulb, and the two variants are not interchangeable with each other despite their similar form factor.
• The H4651, H4652, and H4656 are all 4x6-inch rectangular sealed beam units used across the 1982-1992 Camaro in various low beam and high beam configurations. All three are sealed beam assemblies requiring full unit replacement, and their designations reflect distinct beam pattern and filament specifications that make them non-interchangeable across positions.
• The H6024 is a 7-inch round sealed beam unit rated at 12V. It was used for both the high beam and low beam positions in the 1967-1981 Camaro, meaning the same unit type appeared in both positions during that period. Like all sealed beam units in these specifications, the entire assembly is replaced as a single component.
• The 2016-2021 Camaro with halogen capsule headlamps used separate bulb types for high and low beam, with the 9005 or H9 handling high beam and the H11 handling low beam depending on the model year. These halogen variants are not interchangeable due to differing base designs and wattage ratings.
• HID bulbs in these specifications, both D1S and D3S, are designed exclusively for projector-type housings and include an integral ignitor as part of the bulb assembly. Halogen bulbs listed across the same years, such as the 9005, H9, H11, and 9008, are for separate halogen-specific headlamp assemblies and are not compatible with HID housings.
