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

In this review the ASPL 2x16.8 in Emergency Flashing LED Traffic Advisor proves itself as a budget-friendly, high-visibility solution for drivers and fleet operators who need a compact interior warning light. The single biggest reason to buy is its bright, day-visible output from 32 high intensity LEDs and wide optic lenses, which make it effective for temporary or semi-permanent use in vehicles. It is a practical pick when visibility and multiple flash options matter more than a polished exterior installation.

Key Features

• Super visibility: 32 high intensity LED with wide optic lenses provide a bright, concentrated output that remains visible even in daytime conditions.
• Durable construction: The aluminum casing helps dissipate heat and extends the light bar lifespan up to an estimated 50,000 hours for long term use.
• Weather resistant: Fully waterproof and dust resistant construction improves reliability in rain, fog and harsh environments.
• Multiple flash patterns: 26 flash patterns and a double switch control let users choose a pattern that matches their warning needs and recall the last used pattern.
• Flexible installation: Two mounting methods are offered: permanent L-brackets and screws or temporary suction cup mounting for windshield placement.
• Generous cable length: Wired connection includes about 3.9 ft between light modules and roughly 16.4 ft to the cigarette lighter for flexible placement.

Who It's For

The ASPL light bar is a good fit for contractors, service vans, delivery drivers and personal vehicle owners who need a compact interior emergency light that is bright and easy to operate. Its long wiring and cigarette lighter power option make it useful for temporary deployment in multiple vehicles without rewiring.

Those seeking a permanently mounted, factory-integrated exterior warning system or a solution that relies solely on suction cups for long-term highway use should look elsewhere; several users reported suction cups can fail, so permanent bracket mounting is recommended for sustained reliability.

Frequently Asked Questions

Can this unit be used temporarily without wiring into the vehicle?
You can power the lights via the included cigarette lighter plug for temporary use and move them between vehicles without hard wiring.

Are the lights weatherproof for outdoor use?
The housing is fully waterproof and resistant to dust and corrosion, but exterior permanent mounting should use appropriate seals and brackets.

Do the suction cups hold reliably?
Suction cups provide quick temporary mounting, but some users report they can fail; for reliable long term use permanent L-bracket installation is recommended.
