HLauto 6Z4J Dash Strobe Lights — Twin 16.8" Amber/White LED Bars, 48-LED, 20 Modes, Suction/Bracket Mount

These HLauto 6Z4J twin dash strobe bars are compact, 48‑LED amber/white warning lights designed to mount to a vehicle windshield or visor for clear, adjustable hazard signaling.

Built for drivers who need instant, attention‑grabbing illumination, the HLauto 6Z4J pairs a durable ABS housing with aluminum mounting hardware and an upgraded 4D lens to boost output. Each kit contains two 16.8‑inch light bars (48 LEDs total), suction and bracket mounting options, a long power cable, and a multi‑mode controller with memory recall. The lights accept 12V or 24V input and offer a wide selection of flash patterns to match roadside, construction, security, or utility needs.

How do these lights improve visibility during roadside work or traffic control?

The HLauto bars produce bright amber and white flashes through a 4D lens that concentrates and disperses light for increased on‑road visibility. Rapid flash patterns attract attention while steady modes provide constant presence for slower moving operations. The low profile allows placement behind a windshield without blocking sightlines.

• 48 high‑intensity LEDs across two 16.8" bars for stronger output
• Upgraded 4D lens to enhance beam spread and penetration
• Multiple flash patterns for both alert and steady signaling
• Dual color option (amber/white) for regulatory flexibility

How easy is it to install and reposition these visor strobe lights?

Installation requires no drilling: use the adjustable brackets with included suction cups or secure the aluminum brackets for a firmer mount. A 13.12‑foot power cable reaches most dash cigarette lighter sockets, and the controller plugs directly into the lighter for quick setup. Suction cups make temporary placement or frequent repositioning straightforward.

• Adjustable aluminum brackets for secure mounting or removal
• Ten suction cups included for quick, non‑permanent installation
• 13.12 ft cable to reach most vehicle outlets without modifications
• Works with 12V and 24V power sources for cars, trucks, and larger vehicles

What control and durability features should I expect from the HLauto 6Z4J?

The controller offers 20 distinct flash modes plus a last‑mode memory so the lights return to your preferred setting after power interruptions. Housing combines ABS plastic with an aluminum bracket to resist heat, weather, and the sun’s UV exposure, while the LED design stays cool and long‑lasting. This makes the unit suitable for regular field use where reliability is essential.

• 20 selectable flashing and steady modes with memory recall
• Robust ABS housing and aluminum brackets for weather resistance
• Designed to tolerate sunlight without melting or deforming
• LEDs deliver long life and efficient power draw

Will these lights fit inside different vehicle types and be law‑compliant?

The compact 16.8" bars are sized to fit behind most visors, across dashboards, or on rear windows of trucks, SUVs, and vans. While the lights offer amber and white colors commonly used for utility and construction, users should check local regulations about emergency lighting on civilian vehicles before installation. HLauto provides clear mounting options so placement can be adapted to meet rules or permit requirements.

• Compact length fits most visors and dash areas
• Amber/white colors suitable for non‑emergency work zones in many areas
• Flexible mounting lets you choose interior or rear placement
• Confirm local laws for permitted vehicle lighting prior to use
