Want to control a light from two places without running new wires?
This Leviton wireless dimmer kit is a clever solution.

It includes a battery-powered transmitter (mounts anywhere with screws) and a receiver that replaces your existing switch.
You get four dimming levels and a 50-foot wireless range—signals go through walls and floors, so it's great for stairways, hallways, detached garages, or anywhere you want extra control without the hassle of extra wiring.
The transmitter has a selectable A/B code to avoid interference if you're using multiple kits.

The receiver fits in a standard wall box and can be combined with other switches.

Requires 4 AAA batteries (not included).

A smart upgrade for added convenience!
