As andy said, only good for daylight hours, so they shouldn't affect your ability to see at night. As for getting one ... I dunno. I don't use one. Acutally, it looks like Customdynamics.com sells them for about $80, and they do have a photoreceptor to automatially de-modulate after dark. I can't speak for that particular product, but I did buy a charging system monitor from them for my previous bike, and it was a great piece of equipment, so I would expect good things from them.

I only use mine when lane splitting on the freeway or in particular situations where I think oncoming drivers making left hand turns may be distracted. And yes, I never leave it running if I'm in a lane following someone. What's the point?andyauger said:This is getting off topic, but I don't use my modulator all the time. I use it on the interstate if I'm coming up on someone to pass. About 30 seconds before the pass seems to work well, and avoids agravating other drivers. Around town and in residential neighborhoods I use it. Very effective at corners and stop signs. It can be annoying, so I don't sit behind anyone for any period of time with it running.
