If you want to shed some light on 2014, you'll have to do it with one of those ghostly halogen or fluorescent bulbs, thanks to a new federal law banning production of the familiar incandescent light bulbs — just one of hundreds of new rules and regulations taking effect across the U.S. with the new year.
Many of the new laws have fundamental and far-reaching effects, like the quiet elimination of the incandescent light bulb familiar to Americans for more than a century.
U.S. companies stopped making 100- and 75-watt incandescent bulbs a year ago, but New Year's Day flips the switch on the second phase of controversial federal legislation, banning production of 60- and 40-watt bulbs.
The government wants you to use more energy-efficient alternatives, like halogen or compact fluorescent bulbs.
"I think the customer doesn't realize what's going on," said Fussell Hughes, manager of Hughes Hardware in Albany, Ga.
"You used to go and buy a 40-watt bulb or 60-watt and knew what light it had and how bright," Hughes told NBC station WALB of Albany. "The problem you're going to have now is you're going to have to learn about lumens, which is the amount of light put out by a bulb."
Incandescent bulbs aren't the only lights going out in the new year.
In two more states — Oregon and Illinois — teens won't be allowed to use tanning beds unless they have a doctor's note. (The ultraviolet light the beds put out can be helpful treating psoriasis, acne and other skin diseases — thus the medical exemption.)
Oregon and Illinois join Nevada, New Jersey, Texas and West Virginia, which already have similar laws — a trend that the Indoor Tanning Association says threatens to take away "very basic parenting decisions such as this."
"Is the next step to ban teens from sunbathing at public beaches and pools?" the association says in a position statement.

Vending machines are also transforming, thanks to new federal regulations requiring them to provide calorie counts for the snacks inside.
Manufacturers say the rule will force them to cut jobs to make up the cost of reconfiguring their machines, but the Food and Drug Administration says the savings in health care costs will dwarf any economic impact on the front end.
