Command attention and maximize safety across vocational routes with the severe-duty performance of the Truck-Lite 97201 Ultraflash II Alternating Flasher Module. Specifically engineered to drive high-visibility alternating emergency, warning, or utility lighting arrays, this premium 8-lamp electronic flasher module is a core safety upgrade for fleet maintenance operations, commercial utility vehicles, tow trucks, and emergency responder platforms.
Built to overcome the sudden filament burnouts and mechanical wear cycles typical of cheap thermal flashers, the 97201 relies entirely on advanced heavy-duty solid-state electronics. To prevent failure from vibration, heat, or hidden humidity, the inner circuitry is completely encapsulated and sealed in a premium polyurethane potting compound within a structural aluminum housing. Operating at a crisp 90 flashes per minute (FPM), this unit delivers a non-audible, alternating "wig-wag" signal pattern. It features an integrated self-resetting safety system that dynamically protects your vehicle's wiring grid against short-circuit overloads without requiring a fuse replacement.
Designed for total fleet versatility, this dual-voltage module natively supports both 12-volt and 24-volt electrical systems and manages up to an impressive 17 Amps per channel (or up to 8 standard 32/3 candlepower bulbs). It works flawlessly with both modern low-draw LED safety strobes and traditional incandescent marker lamps.
Important Installation Note: This premium flasher module features a 4-wire hardwired setup terminating with three 1/4" male spade tabs and one 1/4" grounding ring with factory heat-shrink tubing and 12-inch leads. This unit is meticulously engineered for interior/cab use only—do not expose the housing assembly to direct external chassis moisture, splashing liquids, or heavy road spray.
