Yes, that movement you feel is how the bulbs change from Hi to Lo...a magnet in theback of the bulb unit pulls it in and out. Now in regards to the kit you received, did it come with a box called a Hi/Lo controller? If you purchased a relay with the kit (which you shouldv'e) there should be 4 "boxes". 2 ballasts, 1 relay, and 1 Hi/Lo controller which is roughly the same size as a ballast. If you did not receive this controller, you will not have the high beam function. Now ANY bi-xenon kit should come with one, so either you ordered the wrong kit or they shipped the wrong kit out to you. Either way I would check the instructions, provided the kit came with any, and call the company back. Which company did you order the kit from?
