Can your alarm sign be seen at night? Now it can with LightWatch. The only solar light you can count on to brighten up your security sign at night. Having an alarm yard sign that can't be seen at night is worthless. Light it up with LiteWatch. Our professionally designed home security signs announce that your home is protected. Burglars by their nature are looking for an ''easy score'' and will choose a home that looks vulnerable over one that appears to have a security system.
