LED Stage Marker
Looking for a really small LED marker? Try the Quarter Marker. About the size of a quarter, Quarter Markers are very thin and virtually unnoticeable. Quarter Markers also change color. With the included CR2032 lithium coin cell battery’s positive side facing UP, the Quarter Marker will light up red. When you flip the battery over (change the polarity), the LED changes to green. Also available in red-to-yellow.
