URANT Alternating Flasher Relay Module DC 4.5-30V 10A — Dual-Output, Adjustable Timing

URANT DC 4.5-30V 10A Adjustable Alternating Flasher Relay Module is a compact, dual-output wig-wag controller that lets you set independent on-times for two high-current channels across a 4.5–30V supply.

This module is built to drive pairs of warning or indicator lights with customizable alternating flash patterns. It accepts a broad DC input range suitable for 12V and 24V vehicles, offers heavy-duty 10A capacity per channel, and includes factory-wired leads and mounting holes so you can fit it into automotive, motorcycle, or industrial signal systems without fuss.

How do I adjust the flash timing for each output?

Two separate trim potentiometers control the on-duration of Output 1 and Output 2 independently, enabling everything from rapid alternation to long, slow flashes. Adjusting each pot directly changes that channel’s 'on' period between very short pulses and several seconds.

• Independent pots for Output 1 and Output 2 timing
• Range covers millisecond to multi-second on-times for flexible patterns
• Fine adjustments let you create symmetrical or asymmetric wig-wag effects

Will this module handle high-power LED arrays or vehicle loads?

Yes — each output is rated to handle up to 10 amps, making the module suitable for many LED arrays and incandescent warning lamps commonly used on vehicles and industrial equipment. The broad 4.5–30V input window lets you use the same module in 12V cars, 24V trucks, or other DC systems.

• 10A per channel capacity for heavy-duty lighting
• Wide 4.5–30V compatibility for automotive and commercial vehicles
• Solid PCB and housing to withstand continuous operation

How easy is installation and wiring?

The unit comes pre-wired with color-coded leads and a printed panel diagram so wiring is straightforward: power, ground, and the two outputs are clearly identified. Built-in mounting holes let you secure the module in enclosures or to chassis points without extra brackets.

• Pre-wired leads (color-coded) reduce wiring errors
• Clear printed labeling for quick identification of V+, 0V, OUT1 and OUT2
• Mounting holes included for stable installation

What applications benefit most from this controller?

The module excels wherever alternating high-visibility patterns are required: emergency vehicle wig-wag setups, traffic control beacons, motorcycle indicator systems, or industrial alarm lights. Its combination of adjustable timing and robust current handling makes it a versatile tool for retrofits and new builds alike.

• Emergency and service vehicle warning lights (wig-wag patterns)
• Motorcycle or vehicle turn-signal and beacon installations
• Industrial signaling and safety light arrays

Who is this for: technicians, vehicle outfitters, fleet maintenance teams, DIYers modifying motorcycles or cars, and industrial engineers who need a small, reliable alternating flasher with independent timing and enough current capacity for high-power lamps. If you require adjustable wig-wag control that installs quickly and runs continuously in automotive environments, this URANT module provides a compact, rugged solution without complex programming.
