Yes, the 3047 replaces the 3057.
No, 3057 and 4157 turn signal bulbs are not compatible. While they may look similar, they have different electrical specifications and bases, which means they will not fit or function correctly in the same socket. Always check the vehicle's manual or specifications to ensure you are using the correct bulb type for your turn signals.
tail/stop/turn signal bulb # 3057 park/turn signal bulb # 3157NA
Yes, they more or less are. Both have two filaments, one for the parking light, and one for the brake light or turn signal. The parking light filament of the 3157 is a little brighter than the parking light filament of the 3057. The signal filaments of both bulbs are the same brightness.
Double-check me on this that the rear turn signal uses the brake bulb. That bulb is a 3057. See sources and related links below for more info.
Well. I work at NAPA and it called for a 3057kx which we naturally don't have in stock. But when the customer pulled the bulb out it was a 3157. which will fit in its place. It might be some sort of long life bulb. Just put a 3157 in there. that's what most brake lights are.
The number needed should be in your manual, if not, remove the bulb & there should be a number on the base. When you go to a parts store, just look for the same number.
The correct size is 3057.
3057
Tail and stop bulb = 3057 Park and turn bulb = 3157NAK
2002 model uses the 3057
I don't understand...what's the question? Yes, that's a fairly common bulb size for tail lights or backup lights in late 90s and on autos. I have the same bulbs in my wife's Chevy S10 Blazer. Wagner 12V 3057 bulb. I don't understand...what's the question? Yes, that's a fairly common bulb size for tail lights or backup lights in late 90s and on autos.

Couldn't tell you, they both put out 12.8/14v and 27/6.7W And in size and look they are absolutely identical
