The Dodge Viper brake components utilize 2458, 3057, and 3157 bulb sizes for various lighting applications across the different production versions of the vehicle. The provided information covers a specific range of time starting from 1992 through 2010.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Viper brake light circuit uses two predominant bulb types across its model years: the 3157 and the 3057. Both are dual-filament wedge bulbs in the T25 form factor, rated at 12V with a 27W high-filament and 7W low-filament output, and both conform to ANSI standards applicable in the United States and Canada.
Although the 3157 and 3057 share identical wattage ratings and the same T25 wedge form factor, they are not interchangeable. The two types differ in their base contact configuration, meaning a 3057 socket will not accept a 3157 bulb and vice versa without risk of improper fitment or electrical contact failure.
The Dodge Viper (1992-2001) uses the 3157 bulb for the brake light position, as does the 2009-2010 model year range.
The 3057 bulb is specified for the brake light position on the 2003-2006 and 2008 model years.
The center high mount stop light (CHMSL) on the Dodge Viper (1992-2002) uses the 891 bulb, which is a single-filament halogen type with a PGJ13 base, rated at 12V and 27W.
Because the 891 is a single-filament bulb, it operates only in an on/off state, which is consistent with its dedicated use in the CHMSL position rather than in a combined stop/tail function.
The PGJ13 base on the 891 bulb is a pin-type halogen base, physically distinct from the wedge base used by the 3157 and 3057, making cross-substitution between these bulb families mechanically impossible without a socket adapter.
The dual-filament design of the 3157 and 3057 bulbs allows a single lamp assembly to serve both the lower-intensity tail light function (7W filament) and the higher-intensity brake light function (27W filament) simultaneously within one housing.
