One of the most economical ways to make your sign more safe is to install low voltage bullet lights on your sign brackets. Installing low voltage bullet lights is an easy project. No special skills or tools are needed and most installation can be done in under an hour using only a screwdriver. Low voltage systems are shock-less and safe for use around children and pets. For two lights, be sure to buy our inexpensive transformer rated for 105W. For up to four lights, use our low voltage transformer rated for 210W.
