The HLauto 406D is a low-profile rooftop strobe light bar with 102 high-intensity LEDs that delivers 360° warning visibility in amber and white for 12–24V vehicles.
Built for service trucks, plows, tow vehicles and emergency support vehicles, the HLauto 406D combines a distinctive Golden Gate Bridge–style shell with a compact footprint, powerful LED output and a quick magnetic mount. Its waterproof ABS housing and long cable make it simple to attach, operate and move between vehicles while providing long-lived illumination in adverse weather.
The 406D uses 102 high-output LEDs and a crystal-clear lens to project light in all directions, producing a much stronger apparent flash than many compact beacons. Designed for both day and night recognition, it offers enhanced visibility from long distances.
Installation takes only minutes: clean the metal rooftop surface, position the rubber suction pods with embedded magnets, and plug the cigarette-style power lead into a 12V or 24V socket. The cable length and magnetic base let you attach or remove the bar without tools or drilling.
The unit includes 16 flashing patterns and a memory function that recalls the last selected mode when powered again. Built from impact-resistant ABS with an IP68 water-resistant rating, the 406D is engineered to resist rain, snow, dust and road grime and to deliver long service life.
Strobe color and use are regulated in many jurisdictions. Confirm local rules for amber and white warning lights before installing on public roads. HLauto provides customer support if you need guidance tied to your order or manual.
Who is this for: The HLauto 406D is aimed at tradespeople, fleet operators and first-response support teams who need a portable, high-visibility warning light that installs in minutes without permanent modification. It’s ideal for snowplow drivers, road crews, tow operators, utility workers and anyone who needs a durable, bright beacon for temporary or transferable rooftop use.
Q: Will the HLauto 406D work on both 12V and 24V vehicles?
A: Yes. The 406D plugs into standard 12V or 24V cigarette sockets and operates on either system.
Q: Is the light bar weatherproof for year-round use?
A: Yes. It has an IP68 rating and an ABS housing to handle rain, snow, dust and road conditions.
