Why Operators Run the ULF44
Five amps per channel is a lot of headroom for LED lightheads. You can run more than one light on a channel as long as the combined draw stays under 5 amps. Scan-Lock lets you cycle through the patterns and lock in the one you want without a laptop or programming cable. The small footprint fits behind a body panel or inside a toolbox compartment where a bulkier controller won't.
Fitment
The ULF44 is not vehicle-specific. It is designed for LED and Super-LED® lightheads wired for steady burn. Before you install, confirm that your lightheads support steady-burn operation and add up their amp draw per channel.
