thats those dodgy ones,
i have a few sets of clears, and i have some with spring clips and i have one set like yours that seem to twist in. i can't find a bulb holder that fits and they don't seem to fit into the wings so they are next to useless. sorry mate but i don't have a cure for that, best thing i can suggest is talk to the person you got them off and get some new ones because those are wrong.
