Tail lights for an ezgo st sport 2+2

[Scruff]

Hi everyone - I just recently picked up an ezgo st sport 2+2 gas (2005) I spent the last week reading and wrenching. Tightened the gov to get her up to 20mph by gps (fast enough... dont want to blow it up yet ) Read all the brake adjustment tips and got the brakes working decent. I am now a little stumped. I want to buy some tail lights. The previous owner said it was prewired for them and I found what looks to be three wires coming out on the back passenger side fender. I didnt see any wires on the drivers side.

First question - what tail lights am I suppose to buy? 2nd, do they hook up to each other and just use the power from that passenger side hook up?

Thanks for any and all help and tips.
