SnuffCity - I'm guessing you don't have a Classic. The handle bars are a tad different on the Classic and no interference was realized between the switch housing and the tank. There is plenty of clearance with Classic/Tourer bars.
The night visibility is tremendously improved with the shallow and wide beam of the fog lights. No deer will escape my cyclops vision now. Those chrome deer whistles packaged in pairs, look to be a tad bit bigger than 338 magnums*, aren't worth depending on

Drove by a doe 10 days ago, less than 10 feet away at o'dark 30. She was looking off into the woods totally unaware I was right next to her. She no doubt took a dump when the exhaust sound caught up to her. *Could be as big around as a 50 cal. I don't have one to compare.
