The invention relates to a socket for a baseless vehicle light. The light includes a lens, a circuit board having plural through holes, and a socket. The socket possesses a plugging groove, two plugging holes formed in the plugging groove, a slot bored in each plugging hole, two terminals respectively inserted into one of the plugging holes, a conductive pin located at one end of each terminal to extend through the slot to connect with the circuit board, and plural connecting members set on one side to correspondingly engage with the through holes. A waterproof resin is injected into the lens to cover on the circuit board and the socket to keep the circuit board positioned in the lens. Thus, a plug of an vehicle is, not cut off, directly plugged into the socket, enabling the light conveniently installed in a vehicle.
