Notice the car on the GW; his headlights cause less of an amorphous white glow than this cyclist's.
If your headlight is so bright that you cant be seen behind your headlight - its too bright. It's unnecessary on the trails - other cyclists can see you without the light. But with the light, other cyclists cant see you. Had this been at night, the cyclist coming towards the high beam would be blinded and not be able to see anything.
Do your fellow cyclists a favor:
- No high beam lights on the trails;
- No high beam strobe lights on the trails (this is even worse);
- If you must use a high beam, point it down (at this point this fellow's high beam is pointed straight at me)
- If you must use a high beam, put your hand over it when you come upon oncoming traffic.
