3 Stellar 2025+ Toyota 4Runner Lighting Upgrades from Baja Designs

[OffRoadUSA.com]

Upgrade your 2025+ Toyota 4Runner with powerful Baja Designs grille and fog light kits for bold style, trail‑ready performance, and safer night driving

If you drive a 2025+ Toyota 4Runner and love pushing it off the beaten path, upgrading your lighting is one of the most dramatic performance and style mods you can make. In this guide, we'll walk you through three powerhouse Baja Designs upgrades designed specifically around the 4Runner: a Squadron Pro behind‑grille kit, an S8 10" + S2 Pro grille replacement kit, and the S2 Sport OEM fog light replacement kit for non‑TRD Pro models.

Why Upgrade Your 4Runner Lighting?

The stock lighting on the 2025+ 4Runner is fine for commuting, but falls short when you’re bombing down fire roads, crawling rocky passes at night, or dealing with nasty weather. Better lighting gives you more usable light down‑trail, wider peripheral coverage, and a massive boost in trail confidence.

Upgrading to high‑output LED systems like Baja Designs brings several advantages:

• Huge increase in lumens and usable beam distance compared with stock.
• Better color temperature for reduced eye fatigue and improved contrast on dirt, rocks, and obstacles.
• Rugged, off‑road‑ready housings with impact‑resistant lenses and weather‑sealed construction.
• Vehicle‑specific brackets and harnesses for a clean, factory‑worthy install on the 4Runner.

Think of it like swapping out a cheap flashlight for a high‑end tactical light: same idea, radically different performance.

Product 1: Baja Designs Squadron Pro Behind‑Grille Kit (2025+ 4Runner)

The Squadron Pro behind‑grille kit for the 2025+ 4Runner is all about stealth power – you get serious forward lighting while keeping your factory front‑end look. This kit mounts high‑output Squadron Pro pods behind the grille using model‑specific brackets and wiring.

Key Benefits

• Stealth mounting: Lights are hidden behind the grille, keeping a clean OEM appearance while delivering big performance.
• Massive output: Squadron Pro pods are among Baja Designs’ highest‑output compact lights, ideal for high‑speed off‑road driving.
• Integrated fit: The brackets and hardware are tailored to the 2025+ 4Runner grille shape for a tight, rattle‑free install.
• Switch integration: Kits commonly include harnesses that tie into factory‑style switches or aftermarket switch panels.

This kit is perfect if you want an aggressive upgrade without bolting bars or pods onto your bumper or roof.

Ideal Use Cases

• Fast desert or forest trail runs where you need long‑range spot or driving beams.
• Rural highway use where wildlife and unlit roads demand more visibility.
• Drivers who want “sleeper” looks – no obvious aftermarket bar hanging from the front.

If your priority is down‑range visibility and maintaining a factory‑clean front end, this behind‑grille kit should be at the top of your list.

Product 2: Baja Designs S8 10" + S2 Pro Grille Light Replacement Kit (4Runner)

The Baja Designs S8 10‑inch and S2 Pro grille light replacement kit transforms the front of your 4Runner into a functional light wall, replacing sections of the grille with a tightly integrated light bar and auxiliary pods.

What This Kit Includes

While specific contents vary slightly by configuration, this type of kit typically includes:

• A 10‑inch S8 LED light bar that fits into the grille opening.
• A pair of S2 Pro pods for additional spot or wide‑cornering coverage.
• Vehicle‑specific mounting brackets engineered for the 4Runner grille.
• Plug‑and‑play or near plug‑and‑play wiring harness options.

The S8 bar delivers a broad, bright beam pattern, while the S2 Pros can be configured to complement that with either distance or width.

Benefits for 4Runner Owners

• Bold, aggressive look: Unlike the stealthy behind‑grille setup, this kit puts your lighting upgrade front‑and‑center in the grille.
• Balanced beam pattern: Combining the S8 with S2 Pro pods gives both forward reach and side illumination for technical trails.
• Great for dual‑purpose rigs: Powerful enough for serious off‑road use, but also excellent for rural night driving and overlanding.
• Clean integration: You avoid awkward universal brackets; instead, the kit follows the 4Runner’s factory lines.

This kit is ideal if you want to make your lighting upgrade a visual statement while maximizing usable light across multiple zones.

Product 3: S2 Sport OEM Fog Light Replacement Kit (2025+ 4Runner, Non‑TRD Pro)

The Baja Designs S2 Sport OEM fog light replacement kit is aimed at 2025‑on 4Runner owners with non‑TRD Pro trims who want better fog and cornering light performance without custom fabrication.

Direct OEM Fog Replacement

These kits are built to drop into the factory fog light locations, using brackets and housings shaped to the 4Runner’s bumper openings.

• OEM‑style fit: No hacking up plastic; the brackets use factory mounting points.
• Clean wiring: Harnesses are designed to interface with the stock fog light connectors or simple adapters.
• S2 Sport output: The S2 Sport is a compact but potent cube that significantly outperforms stock fogs in brightness and beam quality.

Because the lights sit low and wide, they are perfect for cutting through mist, dust, and snow, and also for lighting up the immediate area in front of the truck on tight trails.

Perfect For Non‑TRD Pro Trims

If you’re running SR5, Limited, or other non‑TRD Pro trims, this kit is a direct way to match or exceed the lighting performance often associated with premium packages. It is one of the most cost‑effective lighting upgrades you can make on a 4Runner because you’re replacing a weak factory component with a high‑end off‑road fixture right where you need it.

How These Three Upgrades Work Together

You don’t have to choose just one of these kits. The magic happens when you combine them and build a layered lighting system around your 4Runner.

• Behind‑grille Squadron Pro kit: Primary high‑speed forward lighting with serious throw.
• S8 10" + S2 Pro grille kit: Fills in mid‑range and wide field of view while giving an aggressive visual upgrade.
• S2 Sport fog replacement kit: Low‑mounted lighting for fog, dust, snow, and slow‑speed technical work.

By stacking these together, you get coverage from the front bumper area all the way out to long‑distance spot illumination, with no major dark spots in front of the vehicle. This layered approach is exactly how experienced off‑roaders build lighting on desert and overland trucks.

Choosing the Right Lighting Package for Your Driving Style

To pick the best combination for your 4Runner, start with your primary use case.

Mostly Daily Driving with Occasional Trails

• Start with the S2 Sport fog light replacement kit to boost low‑beam performance, visibility in bad weather, and close‑range trail lighting.
• Add the S8 10" + S2 Pro kit if you want a more aggressive look and better visibility on dark backroads.

This combo gives you major improvements while remaining very usable for everyday driving environments.

Weekend Warrior and Exploration

• Make the behind‑grille Squadron Pro kit your first major upgrade for serious forward light at speed.
• Pair it with the S2 Sport fog replacements so you have both distance and low‑mounted fill.

This setup is tailored for drivers who hit trails regularly and want a big jump in performance without going overboard.

Heavy Off‑Road, Overlanding, or Night Runs

• Run all three: behind‑grille Squadron Pros, the S8 10" + S2 Pro grille kit, and the S2 Sport fog replacements.
• Use switches or a control panel to group lights into usable zones (fog, mid‑range, long‑range) so you can customize output for any condition.

With this setup, your 4Runner stops feeling like a factory SUV at night and starts behaving like a purpose‑built off‑road rig.

Installation Considerations for 4Runner Lighting

Before you click “buy,” factor in installation complexity and supporting components.

Fitment and Compatibility

• Confirm that the behind‑grille kit and grille replacement kit are listed for 2025‑on 4Runner models, as grille shapes and mounting points may differ from earlier generations.
• For the S2 Sport fog replacement, make sure you have a non‑TRD Pro trim, since TRD Pro bumper and fog housings differ.

Checking these details prevents surprises on install day and ensures everything lines up correctly.

Wiring and Switching

High‑output LEDs draw more current than stock, so harness quality matters.

• Look for kits that include fused, relay‑based harnesses designed for lighting loads.
• Decide whether you want to tie into factory interior switch locations or use an aftermarket switch panel system.
• Route cabling carefully around the radiator, fans, and moving suspension components to avoid chafing.

A clean wiring job not only looks professional but also reduces the risk of electrical gremlins later.

DIY vs Professional Install

Many 4Runner owners with basic tools and patience can install these kits at home.

• Behind‑grille and grille replacement kits often require removal of grille trim pieces and careful alignment of brackets.
• Fog light replacement is generally simpler since it uses factory mounting locations and connectors.

If you’re not comfortable with wiring or trimming plastic, a professional shop can usually handle the install in a few hours.

Feature Highlights to Look For

When comparing these and similar 4Runner lighting kits, keep an eye on specific performance specs and design features.

Output and Beam Pattern

• Lumens: Higher total lumens generally mean more raw light output, but the beam pattern (spot, driving, wide‑cornering, or combo) determines how usable that light is.
• Color temperature: Neutral white around 5000–6000K is common on high‑end off‑road lights and enhances contrast on natural terrain.

For a daily‑drive plus trail rig, a combo of driving and wide‑cornering patterns often works best.

Durability and Weather Resistance

• Look for IP‑rated housings for dust and water resistance.
• Opt for lights with hard‑coated, impact‑resistant lenses that can handle rock strikes and trail abuse.

Quality construction pays off when your 4Runner is dealing with rain, snow, mud, and washboard roads.

Vehicle‑Specific Design

Generic bars can work, but 4Runner‑specific kits save time and look better.

• Pre‑bent brackets match the grille or bumper contours.
• Harness length and connectors are designed for the 4Runner’s engine bay and interior layout.

This attention to detail is one of the biggest reasons enthusiasts gravitate to branded, vehicle‑specific kits over no‑name bars.

FAQs about 2025+ 4Runner Lighting Upgrades from Baja Designs

Do I need to upgrade my 4Runner’s wiring to run these Baja Designs kits?

Most vehicle‑specific kits include harnesses engineered to handle the current draw of the lights without overloading factory circuits. You typically run power directly from the battery through a fused relay, then trigger that relay with an interior switch. Always follow the supplied instructions and never just tap high‑output lights into thin factory headlight wiring.

Are these lighting upgrades legal for on‑road use?

On‑road legality depends on your local regulations and how you aim and use the lights. Fog light replacements that follow OEM placement and proper aiming are often more road‑friendly, while high‑output bars and behind‑grille kits may need to be used only off‑road or when no traffic is present. Check your state or country’s lighting laws, especially regarding auxiliary high‑beam lighting.

Will these kits work with my 2025 4Runner if it’s not a TRD Pro?

Yes, the S2 Sport OEM fog light replacement kit mentioned here is specifically designed for 2025‑on non‑TRD Pro 4Runner trims. The behind‑grille Squadron Pro kit and S8 10" + S2 Pro grille kit are also targeted at the 4Runner platform, but always double‑check the fitment notes for your exact year and trim before buying.

Can I run all three kits at the same time without draining my battery?

When wired correctly with relays and appropriate fusing, you can run multiple LED kits safely because modern LEDs draw far less power than old halogen or HID systems for the same light output. For extended idling with lights on, a healthy battery and alternator are important, and frequent night‑time overlanders sometimes upgrade to higher‑capacity batteries or dual‑battery setups for extra headroom.

What’s the best first lighting upgrade for a 4Runner on a budget?

If you’re cost‑conscious but want a noticeable improvement, start with the S2 Sport OEM fog light replacement kit for non‑TRD Pro 4Runners. You’ll see a major increase in near‑field and bad‑weather visibility, and you can always add the behind‑grille Squadron Pro kit or the S8 10" + S2 Pro grille kit later as your needs and budget grow.
