Hello GG--

I've only been commuting since this past spring, so I'm not an expert like some folks here, but here are my $0.02....

Every time my husband goes to Performance, he brings me another blinking light! So I have one blackburn light on my seatpost, one blinking (something generic) on the back of my trunk (right above the seat post), one planet bike blinking on each of the seat stays. I heard that the human eye can't judge distance of a blinking light. I don't know if that's true or not but I leave the one on my seatpost on solid just in case. They all just use 2 AA batteries. I know the blackburns get really good reviews, but I think the planet bike lights are brighter. Then I also have guppie lights on my helmet. I know it's overkill, but for $10 each or whatever they are, better overkill than roadkill.

The brightest flashing front light we have is a 5-LED cat eye, which I use when I don't need my headlight. I have a nite rider headlight. It was really cheap, but it took us a long time to get it back when we had to send the battery for repair. Careful on the front light--we've noticed that if whatever you're mouting it to isn't round, they don't all fit.
