Narrative:

Enroute to imt after aircraft maintenance; we obtained the weather at imt and with 1 mile visibility I advised the ARTCC controller that we wanted the ILS 01 approach. We were cleared for the approach and told to contact advisory frequency. I made a traffic advisory on 122.8 that we were on a 10 mile final on the ILS 01 approach at imt. Unicom called and asked if we had any passengers to deplane and we advised we did not. I also keyed the mike 7 times to activate the approach lighting system and runway lights on high intensity. Intercepting the glideslope I concentrated on my pilot monitoring duties and altitude callouts. At about 1000 feet AGL I started getting ground contact and shortly thereafter I identified the runway and called it in sight. At this time I noted that the approach lights were not lit and quickly keyed the mike 7 times and they came on to high intensity. The PIC advised he had the runway in sight and I advised I was now monitoring the instruments and continued to make the appropriate callouts. I occasionally would look outside briefly to monitor our visual descent and while we had the 1/2 mile visibility minimums I could not see the far end of the runway which would have been 1 1/2 miles distant. During the landing my attention was mostly inside the aircraft performing performance monitoring duties. As we slowed to turn left at the midfield taxiway the PIC remarked about something at the distant end of the runway; possibly snow removal equipment. I focused on the far end of the runway and a single snow removal vehicle pulling a sweeper appeared out of the obscuration of snow; which was probably being produced by the sweeper. Neither of us heard any calls that snow removal equipment was on or in the vicinity of the runway.
