A lighting connector including a terminal enclosure, an adapter circuit board and an insulating layer. Multiple terminals are enclosed in the terminal enclosure. A first side of the adapter circuit board is provided with multiple terminal contacts with which the terminals are respectively soldered. A second side of the adapter circuit board is provided with multiple wire contacts with which multiple signal wires are respectively soldered. The insulating layer encloses the terminal enclosure, the adapter circuit board and the signal wires. The insulating layer is made of a transparent material. At least one light-emitting element is arranged on the adapter circuit board. Two electrode pins of the light-emitting element are connected to a set of printed power circuits of the adapter circuit board. After turned on, the light-emitting element emits light which goes through the transparent insulating layer to outer side.
