I personally want to get them to help be seen as well. A little on the bottom of my side fairings and maybe one under the tail near my license plate.
I dont consider them tacky. Its not like your going down the street as a neon bulb or something, your just putting a few on the bike. I wouldnt be able to figure out whats funny about someone having neons on their bike, especially when the number one cause of bike wrecks is a car that has failed to see them.
Dont do something to satisfy other people, do it for you man. In the end your still a biker just like every other guy that rides a bike, you just have more confidence in being seen at night
