In Boulder, about two-thirds of stop lights use energy-efficient bulbs.

In the push to save more energy, towns and cities across the country — including Boulder — have begun installing stop lights that use energy-efficient LED bulbs instead of incandescent ones.

The lights are so efficent, in fact, that they don’t give off enough waste heat to melt out the lights during winter storms, which some police in the Midwest say  have caused accidents in some parts of the country.

In Boulder, city officials say they haven’t noticed more accidents.
