Emergency strobe lights with 16 flash modes

Technical details

Sixteen selectable flash patterns give these red-and-white emergency strobe lights more than one way to signal a warning. The patterns include full brightness, left and right directions, pulsing and alternating flashes, with a memory function that recalls the last pattern used. That range may be useful when the warning needs to be visible from inside a vehicle without choosing a mode from scratch each time.

The light bar uses 16 LEDs behind a crystal PC lens and has an aluminium body. It is designed for DC 12V power and connects through a cigarette-lighter adapter with an on/off switch. Six suction cups attach it to a smooth front or rear windshield, the mounts are adjustable, and installation does not require drilling or cutting.

What it suits

It may suit you if you need a removable warning light for a truck, tow truck, postal-service vehicle, snow-clearing vehicle or another DC 12V vehicle. For example, a driver could place it inside the rear windshield while the vehicle is stopped and select an alternating pattern to make the warning signal easier for approaching traffic to notice. The red-and-white format and several directional patterns offer more signalling choices than a basic single-pattern light.

The product is intended for use in daylight or at night, and its description claims resistance to water, dust and corrosion. Those claims may be relevant for vehicles used in rain, snow or fog, though they do not establish how it will perform in every condition. It is described as an interior windshield light, rather than a permanent exterior-mounted bar.

Usage tips

Choose a smooth, clean area of glass so the suction cups have a suitable surface, then position the bar where it does not obstruct the driver's view. Connect the cigarette adapter and use its switch to turn the light on and select a pattern. A quick check of the recalled setting before setting off can help avoid needing to change modes while driving.

Without having tested it, the main practical constraint is the mounting method: suction cups are specified for smooth windshields, so they may not suit textured surfaces or a vehicle where the bar needs a fixed, drilled installation. Keep the power requirement in mind as well, the listing specifies DC 12V, not a universal vehicle power supply.

Buying questions

Does it remember the selected flash pattern? The description specifies a last-pattern memory recall function, so it is intended to return to the previous setting.

Can it be installed without drilling? Yes. It uses six adjustable suction cups for a smooth front or rear windshield, with no drilling or cutting required.

Is it suitable for a 12V vehicle? It is designed for DC 12V and comes with a cigarette-lighter adapter. Check that your vehicle has a compatible power outlet before choosing it.

Before you buy it

This is worth considering when removable mounting, multiple flash patterns and a red-and-white signal matter more than a permanent installation. It may be a more flexible approach than a single-pattern light, particularly if you expect to switch between directional and alternating signals. It may not suit you if your vehicle lacks a DC 12V outlet, has no smooth glass for the suction cups, or requires a fixed external mount. The listing does not provide dimensions, so check the available space on your windshield before deciding whether the light bar will fit without obstructing your view.
