Nilight 40LED Traffic Advisor Light Bar — Amber-Green 12V with Suction Cups & 30 Flash Modes

Nilight’s 40LED amber-green traffic advisor is a compact, 12V strobe light bar that gives high-visibility directional and hazard signaling for trucks, construction vehicles, and emergency use.

Designed for interior or windshield mounting, this traffic advisor combines bright dual-color LEDs with multiple flash patterns and a memory function so you return to the last-used pattern. Its lightweight ABS/PC housing, long power cord, and included installation hardware make it a practical add-on for any 12V vehicle needing improved roadside visibility or traffic direction without drilling or permanent modification.

How bright is the Nilight 40LED traffic advisor and when will I notice the difference?

The bar uses 40 high-intensity LEDs with a PS magnifier design to concentrate output and increase perceived brightness. That boost enhances visibility day and night so other drivers spot your vehicle earlier in low-light, rain, or busy work zones.

• 40 high-brightness LEDs for stronger output
• PS magnifier lens for focused light distribution
• Low power draw for longer use from a 12V source

What mounting and wiring options are included for vehicle installation?

Nilight supplies four adjustable brackets and ten suction cups so you can position the bar on a front or rear windshield or on the instrument panel without drilling. The long power lead and plug-ready cigarette-lighter connector let you power the unit quickly and move it between vehicles if needed.

• Four adjustable brackets for varied angles and placement
• Ten suction cups for secure, tool-free attachment
• 2.36 ft between lights; 16.4 ft power cord to cigarette lighter

Which flash modes and controls are available for directing traffic or signaling hazards?

The controller offers 30 distinct flashing patterns and a memory feature that restores the last chosen mode after power is removed and reapplied. Patterns include steady, alternating, and directional sequences suited to traffic advisory, hazard alerts, and scene protection.

• Thirty selectable flashing modes for varied signaling needs
• Memory function returns to previous mode after restart
• Easy plug-in operation via standard 12V cigarette plug

How durable is the light bar and what vehicle types is it suited for?

Built from ABS and PC materials, the housing resists high temperatures and is rated for long service life—up to approximately 50,000 hours under normal use. The unit is intended for all 12V vehicles where temporary or removable visual warning is required, including maintenance, construction, and emergency support roles.

• ABS/PC construction for heat resistance and durability
• Estimated service life up to 50,000 hours
• Compatible with trucks, vans, pickups, trailers, UTV/ATV, and more

Who this is for: Installers and operators who need a portable, high-visibility traffic advisor—fleet drivers, contractors, volunteer responders, and municipal crews—will appreciate Nilight’s blend of brightness, selectable patterns, and tool-free mounting. If you want a removable, durable strobe bar that plugs into a 12V outlet and gives clear amber and green directional signaling without permanent installation, this model is built to meet those needs.
