Chevrolet Camaro Brake Bulb Size

Additional Notes

• The 2057 bulb is the most frequently specified brake bulb across the Chevrolet Camaro's history, covering model years 1984-2002. It is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with filaments drawing 26.9W and 8W respectively.
• The 1157 bulb shares the same BAY15d bayonet base as the 2057 and is physically interchangeable in many sockets, but the 2057 produces a noticeably brighter high-intensity output at 26.9W compared to the 1157's 21W high filament. The Camaro transitioned from the 1157 to the 2057 between the 1983 and 1984 model years.
• The 1157 bulb was the specified brake bulb for the Chevrolet Camaro from 1967-1983, covering the first three generations of the model. It is a dual-filament bulb rated at 12V, 21W/5W with a BAY15d bayonet base.
• The 3157 bulb was specified for the 2010-2013 Camaro brake light position. It is a dual-filament wedge bulb in the T25 form factor, rated at 12V with filaments at 27W and 7W, and it is not interchangeable with the T20 wedge bulbs used in later model years.
• The 2016-2018 Camaro models fitted with Halogen Capsule Headlamps use the 7440, a single-filament T20 wedge bulb rated at 12V, 21W. Because it carries only one filament, it is not a drop-in replacement for the dual-filament 7443 used in the 2014-2015 models, despite sharing the same T20 wedge form factor.
• The 2014-2015 Camaro models fitted with Halogen Headlamps use the 7443, a dual-filament T20 wedge bulb rated at 12V, 21W/5W. Substituting a 7440 in place of a 7443 would result in the loss of one filament's function, as the 7440 lacks the second filament entirely.
• The center high mount stop light on the 1986 Camaro uses the 906, a miniature T10 wedge bulb rated at 12V, 8W. This is a single-filament bulb suited only to a stop light function with no dual-intensity capability.
• The 1987-1990 Camaro center high mount stop light uses the 891, a single-filament halogen bulb with a PGJ13 base rated at 12V, 27W. The PGJ13 base is a dedicated halogen fitting and is not compatible with standard wedge or bayonet sockets used in other positions on the same vehicle.
• The center high mount stop light specification changed three times across the 1986-1992 model years, moving from the 906 in 1986, to the 891 for 1987-1990, then to the 2356 in 1991, and then to the 3156 in 1992. Each of these bulbs uses a different base type, meaning none of them are directly interchangeable with one another.
• From 1993-2002, the Camaro center high mount stop light was standardized on the 921, a single-filament T15 wedge bulb rated at 12V, 16W, representing the longest uninterrupted run of a single bulb type in that position across the specifications provided.
