I am using the Light & Motion Urban 300 for the front and their VIS180 for the rear. The VIS180 is awesome for the rear tail light, very bright, has 180 degree visibility, rechargeable and the angle of the light can be adjusted. The 300 has plenty of light for me as 80% of my commute is lighted bike lanes. I am thinking of adding a second front light that I would put in flash mode.
