LIGHTS ARE REQUIREDMUST HAVE A FRONT AND REAR LIGHT TO RIDE
Bike Lights in the Colorado National Monument
The Colorado National Monument (a unit of the National Park System) requires all cyclists (regardless of whether they are in a cycling event or on their own) to have a white light that is visible from a distance of at least 500 feet to the front and a red light that is visible from at least 200 feet to the rear. The Monument has 3 tunnels, bored through solid rock, that does not have lights, thus the reason for the safety requirement. Also, all cyclists and support vehicles are required to use the lights in the three tunnels (you may turn them off once you’ve exited).
