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

In this review of the 2x16.8 in white emergency flashing LED traffic advisor strobe bar, the bottom line is simple: it is a compact, high-visibility light set best suited for drivers who need bright daytime-visible warning lights without a large rooftop installation. The reviewer found the twin 16.8 in bars deliver a surprisingly intense output from 32 high intensity LEDs, and the aluminum casing promises long life and weather resistance, making this a practical choice for roadside safety, convoy signaling, or temporary use on vehicles.

Key Features

• Super visibility: 32 high intensity LEDs with wide optic lenses deliver a bright output that remains effective in daylight for improved safety.
• Durable construction: An aluminum casing aids heat dissipation and helps extend the light bar lifespan to long-term use.
• Weather resistant: Fully waterproof and corrosion resistant design offers strong fog penetrability and works reliably in bad weather.
• Multiple flash patterns: 26 flash patterns selectable via a double switch let users choose signaling styles and the unit remembers the last pattern used.
• Flexible installation: Two mounting options, permanent L-brackets or temporary suction cup mounts, let the user install on windshields or rear glass.
• Long wiring: Includes wire between bars and a cigarette lighter lead long enough for common vehicle layouts.

Who It's For

The light bar is ideal for drivers who need a low-profile but bright warning system: utility workers, tow operators, volunteer responders, and anyone running temporary safety lights from inside their vehicle. Its compact twin-bar design suits pickups, SUVs, vans, and sedans where a full rooftop beacon is unnecessary or impractical.

Those who need a permanently mounted, heavy-duty rooftop beacon with professional-grade mountings and military-spec fittings should look elsewhere, and users who rely solely on suction-cup mounting on rough or curved glass may find the temporary mounts less secure over time.

Pros & Cons

Pros

• Very bright daytime-visible LEDs provide strong warning presence on the road.
• Aluminum case and waterproofing improve durability and long-term reliability.
• Wide selection of 26 flash patterns offers flexibility for different signaling needs.
• Two installation methods let users choose permanent or temporary mounting.

Cons

• Suction cups for temporary mounting can be unreliable on some windshields and may require occasional re-securing.

Our Verdict
