It can be hard to give someone precise directions to find your house. If you’re waiting for medical assistance, you want to be sure the responders don’t have to waste time driving around trying to find you. The Westek HomeFinder flashing light controller simply screws into your outdoor light fixture, and it can flash your lights for twenty minutes to make your house easily found. When you need a regular outdoor light, simply flip the light switch on as normal. When you need house identification, flick the switch twice to start the flashing. (You can stop the flashing by turning off the switch.) You can use up to a 100-watt light with the HomeFinder flashing controller. Amazon.com has the HomeFinder controller for $10.91.
