This doorbell button or garage door push button is your choice of a Blue, White, Red, or Green LED.  It can be wired with AC or DC voltage.  It is designed for use with low voltage 16 volt doorbell transformers. Two mounting screws will be provided for the plastic enclosure measuring 2 7/8"High x 7/8"Wide x 5/8"Deep.  

The spacing for the provided housing screws is the standard 2 and 3/16 inches.  

One photo shows a traditional incandescent light on the left and my LED light on the right so that you can see the difference.

The circuit board is manufactured and assembled in Kokomo, Indiana USA by Doorbell Doctor.

THANK YOU.
