Integrated Design: The wiring harness plug has an integrated pre-wired design, and the connector comes with a fully jacketed cable to protect the wires from harsh environments. Black wire to ground, red wire to high beam, yellow wire to low beam, simplifies installation and ensures a stable connection Quality Material: This H4 HB2 9003 wiring harness socket shell is made of durable PVC material to ensure strong insulation and impact resistance. The ceramic base can withstand extreme temperature ranges from -49℉ to 221℉ and is neither easy to melt nor catch fire. Internal 16AWG copper wire is used for superior conductivity and high thermal stability, making it safer to use Reliable Performance: The contacts of this H4 wiring socket are rated at 40A, switching current is 10A, and voltage is 12V DC, ensuring stable electrical performance. Ceramic plug structure can prevent excessive water from entering and adapt to various complex environments Easy Installation: Plug and play design is quick and easy, just remove the old plug and replace it with this ceramic headlight connector. Each set contains two sockets, fit for quick changeovers. Compact size for easy storage when not in use Widely Compatible: This H4 socket is compatible with 4×6 inch, 7×6 inch and 5×7 inch sealed-beam headlamps with a 6.3 inch cord length, suitable for headlamps or fog lamps retrofit for cars, trucks, boats and other vehicles
