This flickering flame board can be used to simulate a miniature burning building or placed in any space where you would like the look of a flickering flames. Board measures about 1-1/4" long by 1/2" wide by less than 1/8" thick. Because it uses LED's it will last virtually forever and all you need to do is connect it to your 12-volt electrical system. It does not get hot and will not interfere with the rest of the lights in your dollhouse or roombox. It also uses about the same current as that of one "grain of wheat" bulb.
