Emergency Flashing LED Traffic Advisor Strobe Light Bar 2x16.8in

Our review of this 2x16.8in emergency strobe light bar finds it best suited for drivers and fleet operators who need a compact, highly visible warning light for daytime and nighttime use. The single biggest reason to consider it is the super visibility from 32 high intensity LEDs per set and wide optic lenses, which deliver a bright, attention-grabbing output. The unit balances durable construction and multiple mounting options, so it works for temporary windshield use or a more permanent bracket installation.

Key Features

• Bright 32 LED array: The 32 high intensity LEDs with wide optic lenses provide a strong, visible flash that cuts through daylight and fog for improved roadside safety.
• Durable aluminum casing: The aluminum housing dissipates heat and helps the light reach a long lifespan, reducing the need for frequent replacements.
• Waterproof and weather resistant: Fully sealed construction resists dust, fog and corrosion so the light holds up in adverse conditions.
• 26 flash patterns: Dual-switch control offers 26 selectable modes and a memory recall so users can keep a preferred pattern ready.
• Two mounting options: Choose permanent L-bracket installation or temporary suction cup mounting for flexible use between vehicles.
• Long wiring: The lights include a 3.9ft interconnect and a 16.4ft cigarette lighter lead to reach common vehicle layouts.

Who It's For

This light bar is aimed at personal vehicle owners, small fleet operators and service technicians who need a compact, high-output strobe for short-term or permanent installation. Its brightness and multiple flash patterns suit roadside assistance, tow trucks, utility vehicles and anyone who needs a visible warning light that performs well during daytime.

Those who require heavy-duty, permanent rooftop warning systems or integrated vehicle electronics may want a purpose-built roof-mounted beacon instead. Buyers who plan to rely exclusively on suction cups for long-term highway use should note that some users report stability issues with suction cups under certain conditions.

Pros & Cons
