Pollak 65-230 High-Temp H4 & 9003 Dual-Beam Headlamp Wiring Harness

Heavy-Duty Heat Protection for H4 and 9003 Lighting Systems

Standard plastic connectors often fail under the high thermal output of H4 and 9003 dual-filament bulbs, leading to flickering lights or melted sockets. The Pollak 65-230 Wiring Harness is the professional-grade solution to this common electrical failure. Constructed with specialized high-temperature housing, this harness is designed to withstand extreme heat, ensuring your high and low beams function reliably when you need them most.

Superior Power Delivery with 14-Gauge Wiring

To achieve maximum brightness from your headlights, your wiring must handle the load without resistance. The Pollak 65-230 is built with heavy-duty 14-gauge (AWG) wire, providing better conductivity than standard factory pigtails. This reduces voltage drop and protects your vehicle’s electrical system from the heat-related stress caused by high-wattage bulbs.

Versatile Installation for Repairs and Upgrades

Whether you are performing a "cut-and-splice" repair on a damaged factory pigtail or simply adding a protective "Plug and Play" extension, the 65-230 is designed for ease of use. It fits seamlessly between your truck's factory harness and the bulb, making it a critical upgrade for commercial fleets and off-road enthusiasts alike.
