I ride home at midnight daily and the lighting is more than adequate. It was pouring last night and that didn't hinder it at all. I will swap bulbs with a more white light but that's just my own personal preference.
In my pre-buy research I came across some complaints about the light, but I like the light. I keep it on high 99 percent of the time. Almost 150 miles on the bike so far, with half of that at night. (city drivin')
