Genssi LED High Beam Bulb Conversion Kit Compatible with Kenworth Truck T660 T600 T370 T270 T170 T470 T440 T880

Upgrade your Kenworth's factory halogen high beams to professional-grade LED performance—up to 3X brighter with crisp white light that cuts through darkness and lights up road signs like never before.

See the Road Like Never Before in Your Kenworth

If you've been running a T660, T880, or any mid-size Kenworth with factory halogen high beams, you know the struggle: dim yellow light that barely reaches past your hood, signs that disappear until you're right on them, and that constant squint on long night hauls. Kenworth built these trucks tough—but the factory lighting? That's where they cut corners.

This GX7 Pro LED conversion kit is built specifically for drivers who demand better visibility without the hassle of retrofitting entire headlight assemblies. Designed for the high beam position only, these LEDs deliver professional-grade output using XD Pro chipsets—the same technology used in commercial fleet upgrades. You get up to 3X the brightness of stock halogens with a clean, white beam pattern that reflects better off reflective signs and road markers.

Key Features at a Glance

• XD Pro LED Chipset: Commercial-grade components engineered for thousands of hours behind the wheel
• Up to 3X Brighter: More usable light where you need it—down the road, not scattered everywhere
• 10X Longer Lifespan: Outlasts factory halogens by years, not months
• Plug-and-Play Installation: Direct fit replacement—no cutting, splicing, or guesswork
• Cooler, Whiter Light: Better color temperature for improved sign recognition and reduced eye strain

Installation & Fitment

Installation is straightforward—remove your factory halogen high beam bulb, plug in the GX7 Pro LED, and secure the connection behind the headlamp housing. No modifications required. The kit is designed to work exclusively with factory halogen headlamps on Kenworth T-series trucks. If you've swapped to aftermarket headlights, confirm your bulb type before ordering.

Built for the Long Haul

Kenworth drivers put serious miles on their rigs, and this kit is built to match that workload. The XD Pro chipset handles heat efficiently and maintains consistent output over time—no flickering, no fading, no failures at the worst possible moment. These aren't cheap eBay LEDs; they're designed for commercial reliability.

Your Benefits at a Glance

• Better Road Visibility: See obstacles, wildlife, and hazards sooner
