In general, vehicle tail lights are lighting devices that are symmetrically mounted on both sides of the rear of a vehicle and are used to display signals to the rear, and include turn signals, brake lights, reversing lights, tail lights, and rear fog lights.

Among them, in the case of tail lights used in large vehicles such as dump trucks, a yellow turn signal light, a white reversing light, a red brake light, a tail light, and a rear fog light are included in a square-shaped housing, and a colored translucent light that closes the housing. It includes a cover, a light bulb corresponding to each light, a reflector that reflects the light from the light bulb, and a wire that supplies power to the light bulb.

In this way, the tail lights for large vehicles are composed of bulb sockets and wires connected so that the bulbs corresponding to the turn signals, brake lights, reversing lights, tail lights, and rear fog lights can emit light by the driver's operation. Each bulb corresponding to each light has a separate bulb. There are difficulties in connecting sockets and wires and combining housings.

In order to solve this problem, in Republic of Korea Patent No. 10-2013516, a plurality of bulb holders (hereinafter referred to as sockets) are formed into which light bulbs of each light are inserted, and an electrode plate through which one electrode is energized is inserted into the electrode plate. It includes an elastic terminal in contact with the tip of the light bulb through which the electrode opposite to the electrode flowing through the electrode plate is energized, and a wire connected to the electrode plate and the elastic terminal to transmit electricity according to a signal, simplifying the connection structure of the electrode connected to the light bulb. A technology that improves assembly is disclosed.

However, the electrode plate is formed as an integrated electrode plate with a socket formed so that a plurality of light bulbs can be inserted into any one electrode at the same time, so it becomes large and heavy, and the materials and production process for forming the electrode plate increase, increasing production costs. This is a growing problem.

In addition, there is a problem that assembly time is delayed in assembling the elastic terminals by adjusting the positions of the plurality of elastic terminals one by one so that the elastic terminals assembled in the housing completely contact the tip of the light bulb so that electricity can flow.
