I've got the Planet Bike Alias SC front light. (Don't know how to paste a picture in here or I'd do that.) It's VERY bright, has 3 different brightness levels, and flashes. I usually use it in the flashing mode because I want to be seen since I commute in a city with lots of traffic. Two of my coworkers have the same light and also like it a lot.

I've got a couple of Planet Bike tail lights, one on my helmet and one on the seat post.

I like to be lit up like a Christmas tree when it's dark outside.

Here's the front light (didn't buy it from this place but they've got a good picture): http://georgegarnercyclery.com/itemd...gId=39&id=1807

Here's the tail light (also didn't buy it from this place): http://kozy.com/itemdetails.cfm?ID=3992
