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 kx bulb has an extra pair of wire contacts (4 instead of 2) per side. This decreases the amount of current each contact has to handle and decreases the amount of heat build up on the socket. The regular 3057 or 3057K bulb can be used, but it will probably burn out a bit faster and can damage the socket over time.
Couldn't tell you, they both put out 12.8/14v and 27/6.7W And in size and look they are absolutely identical
Yes, the 3047 replaces the 3057.
The correct size is 3057.
The 3057KX and 3057LL are both automotive light bulbs, but they differ primarily in their design and intended use. The 3057KX typically features a dual filament design that allows for a combination of different brightness levels, often used in applications like turn signals and brake lights. In contrast, the 3057LL (Long Life) is engineered for extended longevity, providing a longer lifespan than standard bulbs, which makes it suitable for applications where bulb replacement is less convenient.

Tail and stop bulb = 3057 Park and turn bulb = 3157NAK

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.

You can unscrew a light bulb.
