The Quad Control Remote allows you to control up to 4 Roto-Lights individually with the convenience of using only one remote. This user-friendly remote enables you to control each light independently with the sliding switch located on the left side.  After selecting a light, you can activate the power, directions, Emergency Flash and amount of illumination you prefer.  Then, you can select another light and adjust it as well. The LED light in the upper left corner of the remote will turn green when a button is pushed.  The LED light will turn red to indicate the battery needs to be replaced.
