Thanks for the responses. This is a great alternative. I'll def be ordering a set before the Snoball. Won't benefit me much but they help those out behind you.
Anytime. While they will be a huge help to folks behind you in a Snoball setting, there are everyday benefits to you also. The more likely you are to be seen, the less likely someone is going to rear end you in a poor visibility setting, either on or off-road. (Of course you should check local ordnance laws with regard to on road use, but most states seem liberal to; Rear facing marker lights, since they are used for safety and not illumination)
