Traffic Light

Most people prefer the smaller traffic lights that have 8" lens. They are 120 volt operated and normally you would need to add a dimmer or they will blast you out of the room with light. The newer traffic lights have L.E.D.s and I'm not sure how they would work with a dimmer. The older 8" lights used a 80watt bulb similar to others that you may have in your home. Probably need to rig up a switch to change the light from red yellow and green. Should be pretty easy with a visit to a electronics shop.
