Description
Wide-Area Flood Lighting for Off-Road and Worksite Use
Product Overview
The RoadVision RBL4021F is a 21" LED light bar delivering 94W of output and 5252 lumens of bright white light through a 140-degree flood beam pattern. Where long-range spot bars are designed to throw light far down a highway, the RBL4021F is built for broad area coverage illuminating worksites, tracks, and paddocks with wide, even light across close to mid-range distances.
Operating on a wide 10–30V DC input, it suits most 12V and 24V vehicles including utes, SUVs, 4WDs, tractors, and work vehicles. Universal mounting brackets are included for straightforward fitment, and wiring to a switched power source and relay is the recommended installation method.

Frequently Asked Questions
What is the difference between a flood beam and a spot or combo beam light bar?
A flood beam spreads light across a wide angle — in this case 140 degrees — providing broad, even illumination at close to mid-range distances. A spot beam throws a narrow, concentrated beam further down the road. A combo beam combines both. The RBL4021F's flood pattern is best suited to worksites, paddocks, and low-speed off-road use where wide area coverage matters more than long-range throw.
What vehicles is this light bar compatible with?
The 10–30V DC input makes it compatible with most 12V and 24V vehicles. Universal mounting brackets are included. Confirm fitment for your specific vehicle using the Parts Checker on the site before purchasing.
How should this light bar be wired?
Connect to a switched power source via a relay for safe operation. A wiring harness kit is the recommended method — confirm compatible harness options with the supplier.
What is the IP rating and warranty for this light bar?
IP rating and warranty details are not specified in the supplier data for this SKU. Confirm with RoadVision before purchasing if these are a requirement.
What mounting positions suit this light bar?
The RBL4021F suits roof racks, bull bars, nudge bars, and similar mounting positions. Universal brackets are included. For wide-area and worksite lighting, roof or A-pillar mounting positions that maximise the 140-degree spread are typically most effective.
