>Brian,
As for flying your KR at night, that will be directly related to your confidence level in your KR and to your piloting ability. At one of the Gatherings in Kentucky, some guy and his girlfriend flew in from Florida at 3:00am in the morning. I had a motel room across the road from the airport and couldn't sleep when I heard what sounded like a VW speeding by on the highway. I thought to myself, "Bugs" don't run that fast on the highway so I stepped outside to look and saw the KR circling to land. As to getting your restriction lifted, see what you operating limitations state. If you are limited to "day only" unless equiped with proper lighting, or however it's stated, then you may be able to make a log entry stating that the proper lighting for "night VFR" was installed and that may lift the restriction. One of the FAA offices could give you the OFFICAL answer. Larry Flesner
