Out of curiosity I just scrutinized the photo.
It looks like a headlight (one teeny, tiny led) , taillight and brake light combo with rear turn signals. The turn signal switch is built into the headlight housing. What looks like a cigarette lighter plug is actually a brake light switch that one would attach to the brake cable (cable threads through it/ has a set screw for an anchor).
As for the OP's question, it already has been answered very well.
