HLauto 16.8-inch Dash Strobe Light Bars 2-Pack — 48-LED, 20 Flash Patterns, 12V/24V Plug-and-Play

HLauto 2x16.8-inch dash strobe lights are a dual visor-mounted LED light bar system with 48 high-brightness LEDs, 20 selectable flash patterns, and plug-and-play 12V/24V power for instant vehicle visibility.

These HLauto visor light bars are built to increase a vehicle's visibility in traffic situations where extra attention is needed. The pair of slim 16.8-inch bars use an upgraded 4D lens and durable materials to deliver a brighter, more focused strobe than many standard 32-LED units. Designed for windshield or rear-window mounting, they include adjustable brackets, multiple suction cups, and a long power cable for flexible placement inside cars, trucks, and SUVs.

How do these strobe lights improve on a standard dash light?

The HLauto bars combine more LEDs and an upgraded lens to increase apparent brightness and light distribution. That makes the flash patterns more noticeable to other drivers and pedestrians without occupying much dashboard space.

• 48 high-brightness LEDs vs common 32-LED designs for stronger output
• 4D lens concentrates and expands light viewing angles
• Dual 16.8-inch bars provide a wider light sweep across the windshield

What does installation look like and where can I place them?

Installation is plug-and-play: connect to a 12V or 24V cigarette lighter and position the bars using the included brackets and suction cups. The 13.12-foot cable and adjustable mounting hardware let you place the bars on the front windshield or rear window, and reposition them when needed.

• 10 suction cups for secure glass mounting without drilling
• Adjustable aluminum-alloy brackets for angle and fit
• 13.12 ft power cord reaches most dash and rear locations

Which flash modes and controls are available?

The visor light bars offer 20 distinct flashing modes and a memory recall that returns to the last used pattern. Controls are simple: cycle through modes using the inline switch after plugging into a vehicle socket.

• 20 selectable strobe and flash sequences for different situations
• Last-mode memory so you don’t need to reselect each time
• Works with both 12V and 24V systems for broad vehicle compatibility

Are these lights durable enough for daily driving conditions?

HLauto designed the housing and brackets to withstand heat and outdoor exposure better than many low-cost dash lights. The ABS shell and aluminum-alloy mounting hardware resist warping and fading, increasing lifespan under sun and vibration.

• ABS housing resists high temperatures and UV exposure
• Aluminum-alloy bracket for strength and stable mounting
• Quality construction reduces risk of melting or deformation
