Red/Blue 2x16.8 in Emergency Flashing LED Traffic Advisor - High

In this review the ASPL 2x16.8 in Emergency Flashing LED Traffic Advisor is evaluated as a compact, high visibility warning light for drivers and fleet operators who need a bright, easy to fit strobe without permanent vehicle modification. The single biggest reason to buy is the strong daytime-visible output from 32 high intensity LEDs per kit that make the bar notably brighter than many standard strobe lights. Our review finds it best suited to intermittent use where visibility and pattern options matter more than heavy duty permanent mounting.

Key Features

• Super visibility: 32 high intensity LEDs with wide optic lenses deliver a bright, concentrated output that remains effective even in daylight.
• Durable construction: An aluminum casing improves heat dissipation and helps extend the life of the LEDs for long term use.
• Weather resistant: Fully waterproof and designed to resist fog, dust and corrosion so it holds up in poor weather conditions.
• Multiple flash patterns: 26 flash modes with a double-switch control and memory recall let the user find and retain a preferred pattern quickly.
• Flexible installation: Choose permanent mounting with L-brackets and screws or a temporary setup using suction cups for windshield placement.
• Practical wiring: Two-piece design with 3.9 ft between lights and a 16.4 ft cigarette lighter lead for flexible placement in most vehicles.

Who It's For

This light bar is aimed at private vehicle owners, service drivers and small fleet operators who need a compact emergency warning kit that is bright and easy to deploy. It works well for daytime roadside visibility, utility work, and short-term use where a quick install or temporary mounting is desirable.

It is less appropriate for users who require permanent, vibration-proof roof mounting or for situations where suction cups must withstand repeated heavy duty use; customers reported that the suction cup mounting can sometimes fail and those needing a rock-solid long-term roof installation should consider a fully bolted light bar option.

Pros & Cons

Pros

• Very bright output from 32 LEDs gives excellent daytime visibility.
• Wide selection of 26 flash patterns provides flexibility for different situations.
• Aluminum housing and waterproof design improve durability and lifespan.
• Two installation choices make it convenient for temporary or permanent use.

Cons

• Suction cup mounting has mixed reliability and can detach from some windshields over time.
• Not optimized for heavy duty roof mounting without additional brackets or reinforcement.
