ASPL 38.5" Amber LED Strobe Light Bar — 78 LEDs, Double-Sided, Magnetic Mount, 20 Flash Patterns

The ASPL 38.5" amber strobe light bar is a high-intensity, magnet-mounted rooftop warning light with 78 LEDs, 20 flash patterns, and plug-and-play 12–24V operation for vehicles that need dependable visibility.

This strobe light combines broad, double-sided illumination with a heavy-duty magnetic mount and weatherproof aluminum housing so crews and drivers can broadcast a clear visual warning in daylight or adverse conditions. Built to resist vibration and moisture, the unit offers multiple pattern choices, a memory function, and a long power cable for flexible placement on trucks, service vehicles, and emergency rigs.

How bright and visible is this strobe in daylight?

The bar uses 78 high-power LEDs arranged in grouped clusters on both faces to project intense amber flashes that are noticeable in daytime traffic. The double-sided layout increases the viewing angle, helping approaching drivers identify a hazard or work zone earlier.

• 78 total 1W LEDs for strong light output
• Six clustered groups on each side for broad coverage
• Amber color optimized for warning and hazard visibility
• Designed for daytime and low-visibility situations

Will it stay secure on my vehicle and how do I install it?

Installation is quick and non-invasive: four large magnets with thick rubber cups secure the bar to metal roofs without drilling. The magnets pair with a 16.4-foot heavy-duty power cord and a 12–24V cigarette-lighter plug so you can mount and power the unit almost anywhere on the vehicle.

• Four oversized magnetic mounts with rubber pads prevent roof damage
• 16.4 ft cable reaches cab sockets or power sources
• Plug-and-play 12–24V connector for easy setup
• Stable hold under typical driving and worksite vibration

What customization and control options does it offer?

The light bar provides 20 distinct flashing sequences selectable via dual switches on the plug, letting operators tailor the signal pattern to local regulations or on-scene needs. A memory function recalls your last pattern after power cycles so you don’t need to reselect it each time.

• 20 unique flash patterns for varied signaling needs
• Controls located on the cigarette-lighter plug for convenience
• Last-used pattern memory to simplify repeat use
• Switches permit quick on/off and mode selection

How rugged is the unit for outdoor and worksite use?

This light bar is housed in durable aluminum and rated IP67 for water and dust resistance, enabling reliable operation in wet, dusty, or cold conditions. LEDs are long-lived and the assembly is built to withstand road vibration and routine worksite demands.

• Aluminum construction for impact and corrosion resistance
• IP67 rating keeps out water and dust
• LED lifespan typically exceeds tens of thousands of hours
• Operates on standard 12–24V vehicle electrical systems

Who is this for: The ASPL 38.5" amber strobe bar is intended for drivers and crews who need a portable, high-visibility warning light — including tow operators, construction and utility teams, snowplow drivers, municipal services, and fleet vehicles that require quick, non-invasive mounting and reliable daylight visibility. It suits anyone who wants multiple flash patterns, heavy-duty magnets for temporary roof mounting, and a weather-resistant design for regular outdoor use.
