The Pontiac Solstice uses 3757NA and 3157 bulbs for front turn signals, while rear turn signals require 3057 or 3157 bulbs in these specific sizes. The replacement chart covers 2006 through 2009 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Pontiac Solstice front turn signal requires one of two bulb types depending on the trim configuration: the 3157 for vehicles without fog lamps, and the 3757NA for vehicles equipped with fog lamps. This distinction applies across the 2006-2008 model years.
The 2009 model year standardized the front turn signal to the 3757NA exclusively, regardless of fog lamp configuration.
The 3757NA is a dual-filament T25 wedge bulb rated at 12V and features natural amber glass, which produces an amber output without relying on a colored lens or housing.
The 3157 is also a dual-filament T25 wedge bulb rated at 12V with a 27W/7W filament output, where the higher wattage filament serves the turn signal function and the lower wattage filament serves a secondary function such as parking or daytime running light.
The 3057 shares the same T25 wedge form factor and 12V, 27W/7W rating as the 3157, though the two are not fully interchangeable in all applications due to differences in filament orientation and base configuration.
All three bulb types in these specifications, the 3757NA, 3157, and 3057, conform to ANSI standards applicable in both the United States and Canada.
The rear turn signal on the Pontiac Solstice transitioned from the 3157 used in 2006-2008 to the 3057 in 2009, making the rear socket fitment year-specific for the final model year.
The front turn signal socket on fog lamp-equipped Solstice models from 2006-2008 accepts the 3757NA, which shares the T25 wedge base with the 3157 but is not a direct substitute due to the amber glass construction altering light output characteristics.
