Roughly how much current does a 2057 bulb draw?

These are the bulbs that Firebirds (and I think Camaros) use for Brake/Turn Signals. Does anyone know roughly how much current they draw?

Thanks,
Jason

Roughly 2 amps at 12 volts.

The high filament is supposed to be ~32 watts, so amp draw will probably be a little higher and depending on the system voltage at the time. At 12v it would be 2.6A and at 14v it would be 2.29A.
