Front turn signal bulb type

Hi all, just bought a pair of Sylvania Silverstar bulbs for my x's front turn signal in headlight. After the purchase, I found that the bulb type was 3357A/3457A ST. I searched in realoem.com, and it shows the bulb type is 3157K. Did I buy the wrong bulb? What is the difference between 3457 bulb and 3157 bulb? They look same. Thanks for help.

You bought the correct bulb. I have a 2002, and just installed the 3457 Silverstar bulbs about 3 weeks ago .

I bought Euro lights and noticed the bulb socket was different. 3157 dual filament bulbs were in my stock US lights (only one filament is used though) while 7507's are in the Euro lights.
Actually it could be either 3157's which are 2.1amps or 3357's which are 2.23amps.
3157's - US

7507's - Euro

Yesterday, I tried to swap the new bulbs, however I found that the foot was different between 3157 bulb and 3357 bulb, so it is not possilbe to replace the original 3157 bulbs with 3357 bulbs. So damn!

3157's - US7507's - Euro
Those 7507's look like PY21W's, with their offset pins (same as rears). Those stealth bulbs are hard to find in the U.S. Do you know where to get them here at a descent price? Silverstar makes them, but no one stocked them .
