Doorbell Wiring Conundrum

I am trying to install a new doorbell. My old one has lights inside on the doorbell unit itself, and a lighted switch outside the door. The new one will not have a light on the doorbell unit itself.

The old unit has two power connections, new one only has one. Also the old one shows one red wire just hanging there, not connected to a darn thing!

Wondering if anyone can weigh in on this? Voltage etc. okay already checked. See below for illustrations. (old pic shows top two wires as power wires, 16 volt. New pic shows only one connection for power.)

Thanks for any help!

Your old one of course needs both sides of the 16volts to light that lamp. The new one connects one side of the 16 volts to the terminal marked TRANS. The other side goes to the button and is returned to the other side of the bell coil at the terminal marked FRONT ( same for REAR if you have 2 buttons.)'
You will need to sort out what wires do what and hook up accordingly. It would help to draw yourself a diagram of the electric circuit, then match actual wires to the diagram.

Unlike a normal circuit, these door bell buttons are basically in-line on the "hot" conductor, so treat it like a normal switch, and let it's lighting up surprise you. Don't worry about the light in the button.

Also, pay attention to "This Side Up" arrows. Your chime could sound funny or fail if misinstalled.

I've only installed that brand horizontally, it looks as though you would have to mount it vertically to cover the old paint.
