Additional Notes

The Pontiac Solstice backup light specifications cover the 2006-2009 model years, with two distinct bulb types used across that range.
The 3057 bulb is specified for the 2006-2008 model years, making it the more frequently referenced bulb type in these specifications.
The 2009 Pontiac Solstice uses the 3047 bulb, which differs from the 3057 used in the three preceding model years.
Both the 3047 and 3057 are ANSI-standardized bulbs recognized in the US and Canada, and both share the T25 wedge form factor operating at 12 volts.
The 3047 is a single-filament bulb rated at 27W, meaning it serves one lighting function at a fixed output level.
The 3057 is a dual-filament bulb rated at 27W and 7W, meaning it supports two separate brightness levels or lighting functions within a single housing.
Although the 3047 and 3057 share the same T25 wedge base and 12V operating voltage, their filament configurations are not the same, and the two types are not interchangeable without accounting for that difference.
The shared T25 wedge base between the two bulb types means physical fitment into the socket is structurally similar, but electrical compatibility depends on the specific circuit design of each model year.
