Description
Brute Power from RoadVision's Biggest Curved Dual Row LED Bar
Product Overview
The RoadVision RBL6420C is a 42" curved dual row LED light bar from the DCX2 Series the next generation in large-format curved light bars. Packing 80 x 3W Osram Hi-Lux LEDs into a 240W combination beam output, it delivers 21,600 lumens of intense white light with a beam reaching 932m at 0.5 lux, combining long-range forward penetration with wide roadside illumination.
The DCX2 Series introduces soft start and PWM dimming technology alongside advanced thermal management, all housed in an ultra-slim 65mm deep die-cast aluminium body. At 1073mm long, it provides genuine dual-row output in a profile that offers greater mounting flexibility than previous generation bars. It ships with both low-profile adjustable slide mounts and Roadvision's 9-position anti-vibration end mount system, and connects via a 2-pin Deutsch plug. Backed by a 7-year warranty and rated IP67, it operates across a wide 10–30V DC input for compatibility with 12V and 24V vehicles.

Frequently Asked Questions
What is the DCX2 Series and how does it differ from standard light bars?
The DCX2 is RoadVision's curved dual-row range, designed to deliver maximum output in a wide-format bar. The curved housing provides broader peripheral illumination compared to a straight bar of the same length. The DCX2 generation adds soft start, PWM dimming, advanced thermal management, and an ultra-slim 65mm housing depth for improved mounting flexibility.
What does "combination beam" mean on this light bar?
A combination beam blends spot (long-range forward throw) and flood (wide short-range spread) optics in the same bar. On the RBL6420C this delivers both forward penetration to 932m and wide roadside illumination simultaneously.
Is this light bar PWM dimmable?
Yes. The DCX2 Series supports PWM dimming and is compatible with RoadVision's optional dimmer controller (RDIMG2), sold separately.
What wiring do I need?
The RBL6420C uses a 2-pin Deutsch plug. Compatible wiring harness options include the RBWK standard harness, RBHDWK GEN2 HD harness, and RCWL Airwire remote control loom, all sold separately.
Is this light bar road legal in Australia?
Road legality for auxiliary driving lights depends on state and territory regulations, mounting position, beam type, and wiring configuration. Check your local vehicle standards authority or consult a licensed auto electrician before fitting.
