If you're after serious lighting power for your 4WD or touring rig, a 40 inch light bar is one of the best upgrades you can make—and at PPD Performance, we’ve got exactly what you need to light up the tracks. Whether you're navigating rough bush trails, setting up camp after dark, or just want better visibility for rural driving, a high-quality 40 inch bar gives you unbeatable reach and spread. It’s big enough to handle demanding conditions, yet streamlined enough to mount on roof racks, bullbars, or above the windscreen.

At PPD Performance, we only stock gear we’d run on our own vehicles—gear that’s tough, high performing, and built for Aussie conditions. Our 40 inch light bars feature genuine high-output LEDs, aircraft-grade aluminium housings, and UV-stable powder coat finishes. They’re lightweight, low-profile, and come with changeable beam patterns so you can switch between spot, flood, or combo on the fly. It’s everything you need for clear, safe night-time driving—without the gimmicks.

Types of Light Bars and Beam Patterns

Not all 40 inch light bars are created equal, and the type you choose can make a big difference depending on how you use your rig. At PPD Performance, we offer bars with customisable beam patterns—clip-on covers let you easily switch between spot beam for long-distance vision and flood beam for wide-angle coverage. Want the best of both worlds? Run a combo beam setup and get excellent reach and spread for serious off-road clarity.

Performance and Power Output

When you're pushing through the outback or crawling rocky terrain after dark, you want a light bar that performs every time you flick the switch. Our 40 inch bars are powered by high-output LEDs, delivering intense brightness and consistent beam coverage—perfect for spotting obstacles, wildlife, or trail markers well ahead of time.

Installation and Fitment

Installing your 40 inch light bar should be straightforward—and we’ve made sure it is. Our bars are lightweight and low-profile, with sliding adjustable brackets that make fitment flexible across a range of vehicles. Whether you're fitting to a Ranger, Hilux, 79 Series, or canopy roof rack, you’ll find our clamp brackets and mounts make setup clean and solid.

Value, Durability & Warranty

A good light bar should be an investment that lasts—and our 40 inch units are built exactly for that. With aircraft-grade aluminium housings, these bars are built to take a beating from dust, sun, rain, and road grime. You won’t find cheap plastic parts or questionable wiring here—just gear made to go the distance.

We stand behind what we sell, and that includes offering a solid warranty on our gear. Whether you're heading up the coast or deep into the red centre, you can rely on your PPD Performance light bar to get you there and back with full visibility.

Common Concerns and Maintenance

We get it—there are a few common questions that come up when considering a 40 inch light bar. Will it drain your battery? Not if installed correctly. Our bars are designed to run efficiently, and when paired with the right wiring setup, they’ll draw less current than you’d expect for the brightness they deliver. Wondering if you can use them on-road? Light bars must be used legally, so it’s important to check your local regulations around usage and switching.

Maintenance is a breeze. Give the lens a wipe after muddy or dusty trips, keep the mounts tight, and store the clip-on beam covers when not in use to extend their life. And if you ever want to change up the look or function, we’ve got spare covers in clear, black, blue, orange, flood, spot, and diffused—all ready to go. Just another way we help keep your rig custom and capable.
