This is the electrical socket for the REAR of a MK1 Austin-Healey Sprite Bugeye, your car has 2 of these. These live beneath the rear park lights and operate the rear turn signals, which are single filament bulbs only. The front turn signals are dual filament sockets, as these front lights are park and turn signals. The rears are blinkers only. You will need two of these for the rear and two of our dual sockets for the front.
