HID Waterproof Auto Connector Kit – 1–6 Pin with 15cm 18AWG Wire for Car & Truck Harness

HID-style waterproof automotive connector kits with pre-wired 15cm 18AWG leads — covering 1 through 6 pin configurations for the full range of HID headlight ballast, automotive sensor, and vehicle accessory wiring applications. The 18AWG wire gauge is rated for up to 7A per conductor — appropriate for HID ballast power connections (35W ballast ≈ 3A at 12V; 55W ballast ≈ 4.6A at 12V) and most automotive sensor circuits. Pre-wired leads allow direct splice installation without a crimp tool.

Frequently Asked Questions

What is the current rating for 18AWG wire?

18AWG copper wire is rated for approximately 7A in free air (NEC chassis wiring standard). For automotive applications with bundled wiring (reduced heat dissipation), derate to 5–6A per conductor. For HID ballast connections: 35W ballast draws ~3A at 12V (well within 18AWG rating); 55W ballast draws ~4.6A at 12V (within rating). For higher-current applications (winches, high-power lighting), use 16AWG or 14AWG wire and connectors rated for higher current.

Can I extend the 15cm leads?

Yes. Splice the 15cm pre-wired leads to your harness wire using heat-shrink butt splice connectors or solder + heat-shrink. Match the splice wire gauge to the 18AWG leads (18AWG or heavier). For automotive applications, use adhesive-lined heat-shrink butt splices for a waterproof splice joint — standard non-adhesive heat-shrink does not provide a waterproof seal at the splice.

Are these connectors compatible with Deutsch DT or AMP connectors?

No. HID-style connectors use a different housing geometry and contact size from Deutsch DT and AMP Type 1.5/2.8 connectors. They are not interchangeable. HID connectors are designed specifically for HID ballast and automotive lighting applications where the compact housing size and pre-wired lead format are the primary requirements.

Why order 100 sets?

100-set packs are cost-effective for: automotive workshops stocking common connector types for HID headlight repairs; vehicle accessory installers who use the same connector type repeatedly; and harness builders working on fleet vehicles or production runs. The per-set cost at 100 sets is significantly lower than 5-set pricing, and having stock on hand eliminates reorder delays during installation jobs.

Typical Applications

• HID headlights: Ballast power input connections, igniter output connections
• LED lighting: Auxiliary LED light bar and driving light connections
• Automotive sensors: Replacement sensor connectors for common OEM sensor types
• Truck accessories: Work light, beacon, and accessory wiring on commercial vehicles
• Motorcycle: Lighting and sensor connections on modern motorcycles
