Installing Gen 2 Yangson Design Tail lights

Ok i know this should have been an easy bolt on and replace deally but there seems to be a little problem. The brake/rev section of the tail lights dont seem to like me. The reverse is ok cause there is a socket for the bulb, but the brake portion has a half cut socket wich didnt come with its own outlet for the bulb. so now im stuck. I was wondering if im i missing anthing from this set or is this the way they come. PICTURES REALLY REALLY helpfull thanks to those that reply..any links will help also..

well i decided to install it and i did..what i want to know now is if the red ring around the reverse light supposed to light up...anyone please let me know...
