Lawn Mowers LED Headlight Kit Compatible with Gravely PT ZX ZT HD PT Pro-Turn Z & Ariens Apex Replaces 79108600 79106800 - Zero Turn Mower Light Assembly with Harness Brackets Hardware Review

Overview

If you’re running a Gravely or Ariens zero-turn mower after sunset—whether for commercial landscaping or tackling a large property before the heat sets in—this LED Headlight Kit is the upgrade you’ve been waiting for. Designed as a direct replacement for OEM part numbers 79108600 and 79106800, it’s a complete lighting solution that includes harnesses, brackets, and hardware for a straightforward install. This kit is built for owners of Gravely PT, ZX, ZT, HD, Pro-Turn Z series mowers, as well as Ariens Apex models, and it delivers serious illumination where factory lights often fall short.

Who Should Buy This

• Commercial landscapers running Gravely or Ariens zero-turns: If you’re mowing before dawn or after dusk to beat the heat or meet tight deadlines, this kit transforms visibility. The LED output is significantly brighter than stock halogen setups, making it easier to see obstacles, rows, and property lines in low light.
• Large-property owners (2+ acres): If you’ve got a big yard and find yourself finishing mows in twilight, this kit eliminates guesswork. The wide beam pattern covers more ground, so you’re not squinting or missing edges.
• Homeowners upgrading from dim factory lights: Many stock Gravely and Ariens lights are weak, especially on older models. This kit is a plug-and-play fix that adds modern LED performance without cutting wires or fabricating brackets.
• DIY mechanics who want a hassle-free install: The included harness, brackets, and hardware mean you won’t be hunting for adapters or drilling extra holes. If you’re comfortable with basic wiring (positive/negative connections), you can have this mounted in under an hour.

Key Features Breakdown

• Compatibility with Gravely PT, ZX, ZT, HD, Pro-Turn Z & Ariens Apex: This isn’t a universal kit—it’s specifically designed for these models. That means the brackets align with existing mounting points, and the harness plugs directly into your mower’s electrical system. No guesswork, no modifications.
• Replaces OEM #79108600 & 79106800: These are common factory part numbers for Gravely and Ariens lighting assemblies. If your original lights are cracked, dim, or dead, this kit is a direct swap. It’s a cost-effective alternative to buying dealer-priced OEM parts.
• Complete assembly with harness, brackets, and hardware: Unlike some kits that only include lights, this package gives you everything needed for installation—mounting brackets, screws, and a pre-wired harness with connectors. You won’t need to buy extra fasteners or splice wires.
• LED technology: LEDs draw less power than halogens, produce a brighter, whiter light (typically 5000K–6000K color temperature), and last significantly longer. They’re also more resistant to vibration—important on a zero-turn that bounces over rough terrain.
• Durable housing: The lights are built to withstand exposure to grass clippings, moisture, and UV rays. While not fully submersible, they’re weather-sealed for normal outdoor use and should hold up for years.

Pros

1. Massive improvement over stock lighting: The LED output is easily 3–4 times brighter than the factory halogens on most Gravely and Ariens mowers. You’ll see rocks, sticks, and uneven ground well before you hit them.
2. True plug-and-play for compatible models: The harness matches the OEM connector layout, so you literally unplug the old lights, mount these, and plug them in. No cutting, soldering, or adapter needed.
3. Complete kit with no hidden extras: Brackets, hardware, and harness are all included. At $199.99, it’s cheaper than buying OEM replacements piecemeal, and you get better performance.
4. Vibration-resistant LEDs: Zero-turns can be rough, but these lights are designed to handle the shaking without flickering or failing. Halogen filaments are fragile by comparison.
5. Wide beam pattern: The lights are angled to illuminate the cutting path and edges, not just a narrow spot. This makes a real difference when mowing around obstacles in the dark.
6. Solid build quality: The housings feel robust, and the brackets are thick enough to hold the lights steady. They don’t feel cheap or flimsy.

Cons

1. Limited to specific models: If you don’t own a Gravely PT, ZX, ZT, HD, Pro-Turn Z, or Ariens Apex, this kit won’t fit without major modification. The brackets are model-specific.
2. No dimmer or on/off switch included: The lights are wired to come on with the mower’s ignition (or a dedicated light switch if your model has one). If you want independent control, you’ll need to add a switch yourself.
3. Price point may feel high for a single headlight kit: At $199.99, it’s not cheap compared to generic universal LED bars. But for the direct-fit convenience and OEM-quality build, it’s a fair value.
4. Only one review available: With just a single 5-star rating, long-term reliability data is thin. Early adopters are happy, but there’s no large sample size to confirm durability over multiple seasons.

Bottom Line

This LED headlight kit is a no-brainer upgrade for anyone running a compatible Gravely or Ariens zero-turn who needs better visibility during early morning or evening mowing sessions. The direct-fit design eliminates the headache of adapting universal lights, and the LED output is a night-and-day improvement over stock halogens. At $199.99, it’s a fair price for a complete, hassle-free solution that includes brackets, harness, and hardware. If you’re tired of squinting or missing obstacles in low light, this kit will pay for itself in safety and convenience alone. Strongly recommended for Gravely PT, ZX, ZT, HD, Pro-Turn Z, and Ariens Apex owners.
