As mentioned earlier, everyone ought to check the aim of their headlights as they begin each ride. It helps the rider see the road better and it keeps others from being blinded.
Now, if you want a complaint from me, it's the people in cars that turn on their hazard lights when it rains. Those hazard lights strobe the eyes just like bright bike lights can. Plus, each rain drop on a windshield multiplies the quantity of those hazard lights in a drivers eyes. It's just wonderful, let me tell ya.

I believe drivers ed tells you not to use the high beams in misty, foggy or rainy conditions.
