ASPL 38.5in Strobe Light Bar 78-LED Double-Sided Magnet Mount — IP67, 20 Flash Patterns

This low-profile rooftop strobe from ASPL combines strong illumination and quick installation for vehicles that need reliable visual warning. Constructed from aluminum with IP67 protection, the bar is built to resist moisture and vibration while delivering a broad, attention-grabbing signal from both front and rear faces. The unit’s long power cable and memory-enabled controller make it practical for temporary or semi-permanent use across a range of vehicles.

How bright is the ASPL 38.5" light bar and how is the illumination arranged?

The bar uses 78 high-power LEDs arranged across both faces to create intense, day-visible flashes. LEDs are grouped to spread light evenly across the length, improving visibility for oncoming and following traffic.

• 78 total 1W high-power LEDs for strong output
• Symmetrical front and back LED groups for 360-degree warning
• Designed for daylight visibility and long-range recognition

What mounting options and installation steps are needed?

ASPL provides four reinforced magnets with thick rubber suction bases so the light can be mounted quickly to metal roofs without drilling. A 16.4 ft heavy-duty cable and a 12–24V plug allow simple connection via a vehicle cigarette lighter or hardwire as needed.

• Four strong magnetic feet with rubber cups reduce roof movement and surface marks
• 16.4 ft cable reaches most vehicle interiors for convenient plug-in placement
• Plug-and-play 12–24V connection; no special tools required for temporary use

Which flash patterns and controls are available?

The bar offers 20 distinct flash patterns controlled by dual switches built into the cigarette-lighter controller. A memory function recalls the last selected pattern after power is interrupted, so users don’t need to cycle through modes each time.

• 20 selectable patterns for steady, rapid, or alternating strobe sequences
• Controller-mounted switches for rapid mode changes while seated
• Last-used pattern memory for repeated, consistent operation

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

The housing is aluminum and rated IP67, giving it protection against dust and immersion-level moisture. The LEDs are rated for long service life and the overall build is meant to withstand vibration, making it suitable for heavy-duty and outdoor work environments.

• Aluminum body with weather-resistant sealing for wet and dusty conditions
• Vibration-resistant construction for use on work trucks and utility vehicles
• LED longevity supports high-hour applications such as snow removal or construction

Who is this for: The ASPL 38.5" 78 LED strobe light bar is aimed at drivers who need a portable, high-visibility warning solution—municipal crews, contractors, delivery and postal fleets, plow operators, and private vehicle owners who require occasional rooftop signaling. It’s a practical choice when you want rapid installation, multiple flash modes, and robust weather resistance without permanently modifying the vehicle.
