A wedge base is a type of electrical connector used as a fitting for small light bulbs. It is similar to the bi-pin connector, except that the two "pins" are the same wires that extend into the bulb (rather than being rigid), and the wires are bent up onto the sides of the base, where they make contact with the socket. The wires are usually inserted into a plastic base that the bulb is mounted in, and which is often narrower at the tip than at the bulb, giving it a wedge shape and usually ensuring a tight connection, depending on manufacturing tolerances. Some bulbs have no plastic base, and the wires are simply bent up to the sides of the bulb's glass base.

The bulb is inserted and removed with straight in or out force, without turning as with a bayonet mount or Edison screw, on certain bi-pin light sockets. For true wedges, compression is the force that holds the bulb in, while others use simple friction, or snap into a socket with spring-loaded electrical contacts that "grab" the corners or other protrusions on the base to prevent loosening from vibration. In contrast, a "slide base" (sometimes "telephone slide base") lamp also is inserted in a socket without rotation, but has two long contacts on either side of the lamp envelope connected to the lead wires.

Bulbs of this type are commonly used in automotive lighting and in low-voltage lighting used in landscape lighting. The bulb may have dual filaments, acting as both a low-wattage tail light or parking light and a higher-wattage brake light or turn signal.
