These signs are created with the same EL material as the non-animated signs, with all the benefits and more. Each kit is pre-programmed with 36 different chase patterns, allowing the user to choose which pattern they want. Each pattern has its own action and will light the signs in a different way. You can have a regular flashing sign, a standard chase sign, or something more, for the businesses on your layout. And once a pattern is chosen, it is stored in memory and is remembered each time the sign is turned on again. The patterns can be changed over and over again.
