Auxbeam 20 Inch 420W LED Light Bar - Dual Color Strobe & Driving Light

In this review the Auxbeam 20 inch 420W LED light bar is judged as a practical upgrade for drivers who need a versatile, high-output auxiliary lamp for offroad, work or fog use. The single biggest reason to buy is its combination of a dual-color lighting system and six remote-selectable modes that let users switch between white driving beams, amber fog light, combos and multiple strobe or flashing options, giving clear visibility and warning capability without swapping hardware.

Key Features

• Six lighting modes: The included remote control lets you select white driving, amber fog, combined white and amber, white flashing, amber flashing and white/amber strobe for flexible on-road and warning uses.
• High output brightness: The bar claims a total output meant to deliver a strong spot/flood combo for long forward distance and improved peripheral illumination along road edges.
• Durable construction: A 6063 die-cast aluminum alloy housing and corrosion-resistant PC lens protect the LEDs and optics for rugged outdoor use.
• IP68 waterproof rating: Upgraded sealing and housing design are intended to keep the unit working in heavy rain, mud and other harsh environments.
• No electromagnetic interference: Built-in EMC control is designed to prevent radio interference and reduce flicker for stable electrical operation.
• Adjustable mounting: The included mounting hardware allows angle adjustment for roof racks, bull bars, headache racks and other mounting locations.

Who It's For

The Auxbeam 20 in LED light bar suits offroad enthusiasts, truck and ATV owners, and anyone needing auxiliary fog or warning lights who wants a single unit that performs multiple roles. The remote-controlled dual-color output is particularly useful for those who switch between high-visibility driving beams and amber warning or fog modes.

Drivers who need a simple, purpose-built, single-color auxiliary lamp for highway speeds only or small-size light pods might look elsewhere; this 20 in bar is best where strong forward throw and broad peripheral illumination are required, and it assumes a 12V vehicle electrical system and available mounting space.

Pros & Cons

Pros

• Offers several practical lighting modes controlled by a remote for versatile use cases.
• Robust build with die-cast aluminum housing and corrosion-resistant lens for durability.
• IP68 waterproofing and EMC protection reduce weather and interference concerns.
• Bright spot/flood combo beam improves forward distance and side illumination.

Cons

• Some customers report mixed results with switch or mode button functionality, so control reliability may vary.
• At 20 in and high output, it requires appropriate mounting space and wiring effort for some vehicles.
