Bulbs 1057 vs 2057 - Difference

I know its minor but does anyone know the difference
between the common 1057 and 2057 parking light/
brake light bulbs. They look identical, both have
two elements for light and turn signal/brakes, and
both fit. I use them interchangeably.
What's the difference?

If you mean *1157* and 2057.....

1157 the filiment for the stop/signal has a rating of 32 candle power
and the tail light filiment is 3 candle power.

2057 is 32 candle power for the stop/signal and 2 candle power
for the tail light.

The idea behind this was to make more of a *contrast* between
the tail light and brake light to make it more noticable.
Your right, the average person will not even notice the
difference.

        The older designation (10xx) creates more *heat* than the 20xx
series bulbs.  Therefore, if you use a 10xx bulb in an application where
a 20xx is spec'd, you run the risk of a meltdown of any nearby plastic
components (like your taillamp lens or housing...).  This same situation
exists for certain instrument cluster applications (though obviously with
smaller bulbs), in which the consequences can be very costly.
        Straight skinny:  Use the *correct* replacement bulb, regardless
of what you removed from the socket.
