INTERNATIONAL PROSTAR YEAR 2010 9005 9006 HEADLIGHT RELAY HARNESS KIT Replacement Light

This 9005/9006 Headlight Relay Harness Kit is a comprehensive electrical upgrade solution designed for heavy-duty commercial truck applications. The kit provides enhanced headlight performance and reliability for fleet operators and maintenance professionals working with late-model Class 8 trucks and vocational vehicles. The kit includes two 40-amp weatherproof relays paired with two weatherproof relay bases featuring integrated wiring harnesses. These components work together to optimize electrical distribution to factory headlight systems, reducing voltage drop and improving bulb brightness and longevity. A weatherproof 30-amp fuse rated for up to 150 watts provides circuit protection, while mating connectors ensure proper integration with existing factory headlight assemblies. This headlight relay harness is engineered specifically for the International ProStar model year 2010 and is compatible with a broad range of heavy-duty trucks. The weatherproof construction ensures durability in demanding operating environments, including exposure to moisture, vibration, and temperature fluctuations common in commercial trucking operations. The kit accommodates both 9005 and 9006 bulb types, offering flexibility for various headlight configurations. Typical applications include fleet maintenance, owner-operator truck upgrades, and commercial vehicle electrical repairs. This kit is particularly valuable for operations seeking improved nighttime visibility, extended bulb life, and more reliable headlight performance on long-haul routes. The relay-based design distributes electrical load more efficiently than factory wiring alone, making it suitable for trucks operating extended hours or in challenging visibility conditions. Ideal for use by professional mechanics, fleet maintenance departments, and truck service facilities. Original Model: INTERNATIONAL PROSTAR YEAR 2010 9005 9006 HEADLIGHT RELAY HARNESS KIT
