Description
500W Dual Headlight Relay Harness Kit – 12V/30A | Auto Technologies Network
Fix Dim Headlights & Protect Your Wiring – Direct Battery Power for LED, HID & Halogen Upgrades
The Problem This Solves
Factory headlight wiring wasn’t built for modern high-power bulbs. If you’ve upgraded to LED or HID headlights and noticed flickering, dimming, or melted wires, your stock harness is the culprit — it simply can’t handle the load.
Auto Technologies Network’s 500W Dual Headlight Relay Kit bypasses your factory harness entirely, pulling power straight from the battery so your lights get full, stable voltage every time.
What’s in the Box
- 6-Pin DHL dual relay harness (pre-wired, plug-and-play)
- Heavy-duty 12–14 AWG color-coded wires
- Dual inline blade fuses (one per beam)
- Mounting bracket
- Installation instructions
Key Features
⚡ High-Power Performance (500W / 30A) Handles up to 500W total — 30A per channel for high and low beams. Built for HID kits, LED conversions, and stock halogens on demanding applications.
🔌 Plug-and-Play Installation (10–20 Minutes) No cutting. No splicing. Color-coded wires and pre-assembled connectors make this a true DIY install. Just connect to battery (+/−), headlight switch, and lamps.
🚗 Universal 12V Compatibility Fits 99% of 12V cars, trucks, SUVs, motorcycles, and ATVs — including negative-switched systems (Toyota, Jeep, Subaru) and positive-switched vehicles.
Compatible headlight types: H4/9003, H6054, H6024, 5×7″, 7×6″ sealed beams, and more.
🛡️ Built-In Safety Protection
- External blade fuses on each beam prevent overloads and shorts
- IP67 waterproof sealed relays — rain, heat, and vibration resistant
- Copper terminals + heat-resistant insulation exceed OEM standards
🔧 Premium 6-Pin DHL Relay Design Outperforms basic 4-pin relays with more stable current delivery, longer lifespan, and brighter, flicker-free output.
