Apparently it's to scare birds off, or was that by having the wx radar on? It's different, not all of them have it, unless they're getting the mod. It's more noticable because it sticks out like dogs balls so everyone can see you! and because it looks so @#$%$*, everyone notices it. But it may be safer!
See and be seen!
What do think about it? Do you think it's a good idea?
