As best as I can tell the thing a lot of people seem to have against the stock indicators is that they look like.......................... indicators. I think they work fine, especially with LEDs inside them, and look just like, what's the word, indicators. They therefore give a good indication of where I might be going. Making them small and almost invisible or locating them where they can't easily be seen makes no sense at all.
I really like the Rivco mirrors; they're are an excellent idea because a car next to you can see them and you're more likely to notice if you've left them on.
