Sorry probably should have explained it better. The high beam bulb for the fusion is the h7 bulb for me and the low beam is the h11. The h11 is the push and screw sideway to lock type and the h7 is a bulb that requires a clip, or in this case a spring retainer, to hold it into the housing. Mine is the driver side bulb closest to the grill. Not the projector side. It's sorta like a spring because on two sides it has 90s and goes into two little lips that holds the spring. Then you insert the bulb and push the clip/spring down and lock it against a post on the opposite side. Sorta looks similar to the spring in this pic. http://i.ebayimg.com/00/s/NzEyWDcxMg==/z/kW8AAOSwPe1UHVPb/$_35.JPG The ones with the 90 degree bends on the ends, not the loops.
