Warrior Pre-Runner Folding Roof Rack Light Bar – 2007-2014 Toyota FJ Cruiser | 3850

Give your Toyota FJ Cruiser a classic off-road racing appearance with the Warrior Products Pre-Runner Folding Light Bar, part #3850.

Designed specifically for the 2007-2014 Toyota FJ Cruiser equipped with the factory roof rack, this steel light bar provides mounting locations for five 6¾-inch round auxiliary lights while incorporating a convenient folding design.

Unlike fixed roof-mounted light bars, the Warrior Pre-Runner Light Bar can be folded backward when additional overhead clearance is needed or when you want to protect your auxiliary lights from low-hanging obstacles.

Simply loosen two adjustment knobs, slide the support struts rearward, and fold the light bar down. No tools are required to operate the folding mechanism.

Finished in durable textured black powder coat and manufactured in the USA, this light bar combines functional off-road lighting capability with distinctive FJ Cruiser styling.

Important: Auxiliary lights and wiring are NOT included. Factory Toyota roof rack required.

Classic Pre-Runner Styling

Few accessories give the FJ Cruiser the unmistakable appearance of a desert racing or expedition vehicle quite like a row of round roof-mounted auxiliary lights.

The Warrior Pre-Runner Light Bar provides mounting locations for five round lights positioned above the windshield on the factory roof rack.

The result is a traditional off-road lighting arrangement inspired by the desert racing trucks and SUVs that helped define the Pre-Runner look.

Whether you're building a trail-ready FJ Cruiser, an overland vehicle, or simply want the classic appearance of roof-mounted round lights, the Warrior 3850 provides a purpose-built mounting solution.

Folding Design for Additional Clearance

One of the most useful features of the Warrior 3850 is its folding light bar design.

Fixed roof-mounted auxiliary lights can create problems when entering parking garages, navigating low branches, or traveling beneath other overhead obstacles.

Warrior addresses this issue with an adjustable folding mechanism.

To fold the light bar:

1. Loosen the two adjustment knobs.

2. Slide the support struts rearward.

3. Fold the light bar backward toward the roof rack.

The mechanism allows the light bar to be folded down without removing the assembly or using tools.

This provides additional flexibility when driving in areas with limited overhead clearance.

Always verify actual vehicle clearance before entering garages or passing beneath obstacles.

Mounts Five Round Auxiliary Lights

The Warrior Pre-Runner Light Bar accommodates five 6¾-inch round auxiliary lights.

This configuration provides the opportunity to create a substantial forward-facing auxiliary lighting system.

Depending on your choice of lights, the setup can be configured for applications such as:

• Desert driving

• Trail illumination

• Backcountry exploration

• Off-road night driving

• Overland travel

• Remote-area driving

The bar is a mounting accessory only. The actual light output and beam pattern depend on the auxiliary lights selected.

Recommended Auxiliary Lights

Warrior identifies two light models that work particularly well with this bar:

PIAA 520 Series

• Traditional round auxiliary light design

• Suitable physical configuration for the Warrior mounting system

Hella Rallye 4000 Compact

• Compact round auxiliary light design

• Another manufacturer-recommended option

Other round auxiliary lights may be suitable, but mounting dimensions and clearance should be verified before purchasing.

Important: The 6¾-inch specification refers to the intended round light size. Confirm the dimensions of your specific light housings, mounting brackets, and hardware.

Heavy-Duty Steel Construction

Warrior manufactures the Pre-Runner Light Bar from steel to provide a durable mounting structure for multiple auxiliary lights.

The assembly is designed for use on the FJ Cruiser's factory roof rack, creating a dedicated lighting mount without requiring a complete replacement roof rack.

The steel construction provides rigidity for the light mounting arrangement while maintaining the classic Pre-Runner appearance.

Textured Black Powder-Coated Finish

The Warrior 3850 comes finished in textured black powder coat.

This finish complements the FJ Cruiser's factory black roof rack and exterior trim while helping protect the steel assembly against normal environmental exposure.

The textured finish also provides a rugged appearance that works well with other off-road accessories.

Factory Roof Rack Required

The Warrior 3850 is specifically designed for the original Toyota FJ Cruiser roof rack.

It is not a universal roof-mounted light bar.

If your FJ Cruiser does not have the factory roof rack, or if the factory rack has been replaced with an aftermarket system, compatibility should be verified before ordering.

Installation Requirements

The Warrior Pre-Runner Light Bar mounts to the factory Toyota FJ Cruiser roof rack.

Minor drilling into the factory roof rack is required for installation.

This is an important distinction for customers who want a completely no-drill accessory.

Once installed, the light bar's folding mechanism operates without tools.

Auxiliary lights and their electrical wiring must be purchased and installed separately.

Ideal for FJ Cruiser Off-Road Builds

The Warrior 3850 is an excellent accessory for FJ Cruiser owners who want the appearance and functionality of a traditional roof-mounted auxiliary lighting system.

Common applications include:

• Off-road trail vehicles

• Desert and Pre-Runner builds

• Overland FJ Cruisers

• Expedition vehicles

• Backcountry exploration

• Camping and outdoor recreation

• Custom FJ Cruiser builds

Its folding design is particularly useful for owners who want roof-mounted lighting but also need the flexibility to lower the light assembly when necessary.
