💡 Plug & Play Upgrade – 9005/HB3 & H11 Hi/Low Beam LED Headlight Kit

Upgrade your vehicle’s headlights or fog lights with this high-performance COB LED conversion kit. Designed for both 12V and 24V systems (cars, trucks, SUVs, RVs), this kit delivers instant brightness, clear beam pattern, and long-lasting reliability – no relay or complicated wiring needed.


✅ Key Features

  • Dual Function – Hi/Low Beam
    One bulb handles both high and low beams. 270° low beam with cut-off line prevents dazzling oncoming traffic, while 360° high beam provides full illumination.

  • COB Chip Technology (USA Source)
    4 luminous faces per bulb – no dark spots or blind zones. Produces 6000K–6500K xenon white light for better reflection on road signs and painted lines.

  • Engineering Beam Pattern
    Projects light evenly onto the road at the proper angle. Reduces foggy or scattered light for safer night driving.

  • All-in-One Thermal Management
    Aviation-grade 6063 aluminum profile + 12,000 RPM silent fan work together for efficient heat dissipation. Operating range: -40°C to 80°C.

  • Built-in Constant Current CPU
    Instant full brightness on startup. No external relay or decoder needed for most vehicles.

  • IP67 Rated
    Dust-tight and waterproof – reliable in rain, snow, or mud.

  • 50,000+ Hours Lifetime
