The only real difference between the two that I can see is that the 1157 is rated at 32 candlepower, while the 2057 has 24 according to the specs that I was looking at. Strangely enough they are both rated as 27 watt bulbs.

The difference between 1157 and 2057 is in the "minor" (dim parking or tail) filament. On the 2057, the dim filament produces 2 candlepower. On the 1157, the dim filament produces 3 candlepower. The difference doesn't sound like much, but it's very large as a percentage. Both 1157 and 2057 produce 32 candlepower from the bright (brake or turn) filament
other than that i don't know
