Yes, that socket is called a "bayonette bulb socket", but there is more to it than that. What cought my eye is the fact that you mention an 1157 bulb. "1157" bulbs are 12v, dual filament bulbs, like found in later day tail lights, or parking lights. But NOTE that 1157s have two pins on side of bulb which ARE NOT in line with each other. They are offset!



Now I COULD be wrong, but it sure does look like (to me) that your socket has provision for two pins that are straight across (NOT offset) from each other. In other words, the two slots APPEAR to be equal in septh. A 12v, dual filament bulb with straight-across pins is going to be an 1176 bulb....see pic BELOW!




The socket that you have APPEARS to have "straight-across" pins, and that socket is technically called a "BA15D" type socket, for an 1176 bulb.

The socket for an 1157 bulb with two OFFSET pins uses a "BAY15D" type socket.
