That depends on your state laws. Check with your local Department of Motor Vehicles or garage mechanic. For example, Idaho requires that the low beams light an area of 100-350 feet in front of the vehicle. In Connecticut, low beams must illuminate persons or vehicles at least 100 feet away. However, the state's motorcycle laws differentiate based on the bike's speed-- 100 feet at less than 25 mph, but 200 feet at 25-35 mph, and an illumination of 300 feet if the vehicle is moving at over 35 mph.
Low beam headlights should be able to illuminate objects at least 100 feet away. This distance allows drivers to see pedestrians and other obstacles in the road without causing glare to oncoming traffic. Properly functioning low beams are essential for safe nighttime driving.
Must be at least 500 feet distance between u and the other driver ahead of u. If on divided hwy and cars traveling in the opposite direction are more than 500 feet away you are not required to go to low beams.

Look down to the right hand side and use the edge of the road as a guide. If you are MORE than 500 feet away from the car with it's high beams on, it IS legal to briefly "flash" your high beams on AND right back off. However, if you are LESS than 500 feet from the oncoming car, you could get a ticket for briefly turning your high beams on/off as a reminder-signal to the other driver to "turn off your high beams, buddy!"
If you can see his headlights, drop your high beams. In some states its the law 300 feet at least.
You must dim your high-beams if you're within 500 feet of an approaching car and dim your high-beams within 300 feet of the vehicle you follow.
