The power-pack gives you the ability to be able to attach and illuminate different colours of illumination material simply by plugging the cable into the case. The case has both internal batteries and the ability to plug in external 110v or 240v power.
There is also the option to change the control features fitted into the case when placing the order. You may decide to remove the ability to change the direction of travel of the directional illumination cable, or remove or add in the speed or brightness controls.
This Waysafe Power-Pack enables you to carry a number of different illumination materials within the vehicle these can be used for example to differentiate between Hot Zone marking at one scene and a standard cordon at another.
