Warranty
Warranty Service .
A full 2-year warranty from the original purchase date is offered to the original purchaser on all FEREI lights, covering any defects in materials or workmanship. Please click here to read the full warranty details.
Stated Performance Metrics: Our stated lumen output and beam distance figures are measured under standard laboratory conditions for the light unit only; excluding any losses from mounting hardware, wiring, or vehicle electrical system variance, as is industry standard. A 5% variance (lower or higher) in total light output efficiency is normal for end-user applications.
All FEREI light models must pass our harsh multi-frequency vibration and waterproof endurance tests to ensure reliability. Please see here for more details on IP ratings and usage guidelines.
Max System Voltage: Please ensure your vehicle’s operating voltage is within the light’s rated range (e.g., 12-30V DC). If the vehicle is equipped with other high-power electrical accessories or has an aging electrical system, we recommend having the installation and regular checks performed by a professional auto electrician, as this will help prolong the product’s lifespan and prevent potential issues from power instability.
We are off-road enthusiasts ourselves and understand the critical need for dependable gear. Therefore, we go above and beyond to offer excellent service should you ever experience any issues. We carry a full inventory of spares at very reasonable prices and provide complete technical support.

Technology

Dual-Sided Lighting Solution
Fere's patented dual-side lighting design provides optimal optical cut-off lines and an ultra-wide 260°ilumination angle for a uniquely wide and original lighting experience.

Patent moon shape reflector
Patent moon shape reflector: Arched part reflects the beam right ahead to reach a further distance; crescent part prevents the beam reflecting upwards so to avoid disturbing vehicles across,and also spreads the nearby beam to get a wider range.

Smart Temperature Control System
Equipped with an intelligent temperature control system that monitors the LED in real-time. It dynamically regulates power to manage heat, ensuring smooth brightness transitions and protection against overheating.

Linear dimming
In the design of lighting systems, dimming is an important function. By adjusting the brightness of the light, energy saving, environmental comfort and visual effects can be achieved. FEREI's lighting products all use current dimming, using constant current drive circuits to control the brightness, continuity and linearity of the light. Therefore, there is no noise, no flicker, and no eye damage during the brightness adjustment process.

CNC Precision Machining
CNC machining masters complex shapes with micron-level precision, while aerospace aluminum delivers unparalleled strength-to-weight ratio and durability. This powerful combination ensures parts that are exceptionally reliable, lightweight, and built to last.
