Trailer-mounted LED diesel light tower

A four-head LED tower on a road trailer with its own diesel generating set. The standard unit for highway, rail and civils night work.

Features

Four heads on a rotating yoke let the light be aimed along a carriageway or across a compound without moving the trailer.
LED output means a small engine — often a single or twin cylinder — which is why fuel use is low enough for week-long unattended running.
Individual head switching lets the crew light only the active section, cutting both glare and fuel.
A braked single-axle chassis keeps the unit inside a van's towing limit, which is what makes it movable by the crew rather than by transport.
Lockable cabinet and a wheel clamp point are what keep the unit on site overnight.
