Creates a "halo" glow effect behind switches when light is in the OFF position, making it easier to find the light switch in hotel rooms, bedrooms, storage rooms etc. This device is designed to fit behind most standard 86 x 86mm size 1G/2G/3G single plate switches and functions with both 1-way, 2-way, and DP switches. It can also be used with single sockets if desired.

Will fit behind and work with ALL Knightsbridge 1G switches from their moulded and decorative ranges.
