1157 bulb has two filaments and a socket with two connectors, and two wires. one bulb, both functions park and stop/turn (which are combined, and the brake light will flash when turning).

most aftermarket lights have one 1157 socket and one lens. most stock/original DRIVERS SIDE lights have two sockets and two bulbs, a small 5w for parking (and tag light) and a larger bulb for stop, there was no "turn" without an accessory turn switch and there was no passenger side light without buying the optional one. if you are getting 47-53 housings, be sure to buy a left and a right, the right wont have a tag light lens.

the LED lights I showed have two wires and two intensities, low intensity for park light and high intensity for stop/turn. two wires. ground through the chassis.
