Power-Up Arcade Light Switch Plate ($28)
Light switches are lame. Arcade light switch plates are not. Plus, they’re easy to install. Just pop the plate over the top of your current one, screw it in, and you’re all set. Two AA batteries power it, so you won’t have to fry yourself trying to play the role of an electrician. Check their website to make sure your light switch is compatible. If it’s not, you should probably move.
