Relay Wiring Harness Kit With Fade Control For BMW E46 E36 E38 E39

Enhance your BMW's exterior appearance with the HochiTech Relay Wiring Harness Kit, a specialized accessory engineered to activate a smooth fade-on and fade-off sequence for your Angel Eyes or Halo rings. By integrating directly with your vehicle's remote key signals, this harness triggers your halo rings to gradually illuminate when you unlock the car and softly extinguish when you lock it, creating a premium welcome and departure ambiance. The kit is designed to accommodate up to four halo rings simultaneously and supports both legacy CCFL systems and modern LED conversions. A key advantage for upgrades is its ability to stabilize power delivery for LED replacements, helping to avoid common dashboard error messages that often occur when switching from high-drawn factory tubes to lower-draw diode units.

Installed safely within the vehicle's wiring architecture, this relay kit relies on standard connection points, including the battery, parking lights, and footwell lighting circuit to manage the fade timing. Built-in provisions for fuse integration ensure your electrical system remains protected against surges, while the inclusion of multiple adapters simplifies physical connections across diverse BMW body styles.

Benefits & Installation Tips

• Remote Key Activation: Utilizes the pulse from your existing car key to control lighting behavior, eliminating the need to mount additional switches or modify interior panels.
• LED Upgrade Stability: The relay logic helps bridge resistance gaps when refitting aftermarket LED Angel Eyes, reducing the risk of bulb-out warnings associated with low-current draws.
• Fade Synchronization Advice: For the most natural fading effect, connect the white trigger wire to the positive lead of the front footwell lighting. This allows the halo intensity to ramp up and down in harmony with your interior ambient lights during lock and unlock events.
