<p>PROBLEM TO BE SOLVED: To prevent the damage of a feeder cable and secure the field of view when a vehicle is traveled in a mobile lighting system. SOLUTION: A boom side relay box 17 arranged at the tip section 3a of an expansion boom 3 and a unit side relay box 20 arranged on a lighting unit 5 side are connected by a feeder cable 19 connectable to the boom side relay box 17 via a connector 18. When the connector 18 is removed from the boom side relay box 17, the feeder cable 19 is taken into the lighting unit 5 side, only one connecting terminal of the connector 18 provided on the boom side relay box 17 is left at the tip section 3a of the expansion boom 3, and no feeder cable 19 exists there. The feeder cable 19 is surely prevented from being damaged when a vehicle is traveled or from hindering the field of view of a driver, the durability of a feeder system is improved, and the operability of this mobile lighting system can be improved.</p> |
