Light switch

I'm trying to install a new timer switch. The existing switch has standard (white, black, green) wiring which matches the wires into the wall but the new timer switch has black, white, red and green wiring. I tried to connect the black to black, white to white and green to green and the digital display to the switch comes on but the actual light does not. What am I doing wrong?

Welcome to the forums.

You are trying to connect your timer to a switch loop that has no neutral.
What timer are you using.... can you post a make and model number for it ?
