CUSTOM BI-LED HEADLIGHT INSTALLATION GUIDE





IMPORTANT NOTES

  • Professional installation recommended.
  • Always disconnect your battery before starting.
  • Test Headlights prior to starting installation.

OVERVIEW

LADS Lighting Custom Headlights are engineered for easy installation using factory mounts and plug & play connections. Follow this guide for a seamless install.



What you’ll need:

  • Phillips screwdriver
  • Trim removal tools
  • Soldering iron or Crimp tool
  • Socket set
  • Electrical tape
  • Zip ties
  • Multimeter (optional)
  • Vehicle manual (for reference)


STEP 1: REMOVE FACTORY HEADLIGHTS

  • Ensure LADS Lighting Bi-LED Headlights are not damaged from transit & all components are there.
  • You should have:

  • 2x LADS Lighting Bi-LED Headlights
  • 1x Demon Eye Controller + Extension Wire
  • 1x RGBW Controller + Extension Wire
  • 2x H4 Adapters
  • 2x CANBUS Modules (if vehicle requires them)

  • Remove grille, bullbar, and anything needed to access your existing headlights.
  • Remove headlights, isolating indicators & park lights.



STEP 2: PREPARE & ROUTE WIRING

  • Mount controllers out of direct weather (behind the grille, under radiator support, or behind a headlight depending on the vehicle).
  • Position controllers closer to one side so that wiring reaches both headlights.
  • Plug in CANBUS modules (if supplied) to your H4 vehicle feed.
  • Plug the H4 Adapter into the CANBUS Module (or directly into H4 feed if not supplied).
  • Run extension wires from both controllers to each headlight location.
  • Locate Indicator (+) wires and Park Light (+) wire on one side of the vehicle’s feed.


STEP 3: POWER CONTROLLERS

  • Wire in both controllers, powering them from the same source (splice together for ease of installation).
  • Choose a power feed:

  • Full-time 12V source → Allows controller use when vehicle is off.
  • Ignition source → Powers only when vehicle is on.

  • Splice into Indicator & Park Light (+) wires, insulating connections properly.
  • If removing the factory indicator globe, add a Load Resistor between the (+) & (–) indicator wires to prevent hyper-flashing.
  • Refer to wiring information below for the Wiring Diagram.
  • Ensure all connections are fused (7.5A fuse recommended).





STEP 4: HEADLIGHT INSTALLATION

  • Install LADS Lighting Headlights, plugging in H4 adapters & controllers.
  • Confirm all wiring functions as intended.
  • Adjust beam alignment:

  • Park vehicle 5–10m from a wall.
  • Check low beam height—make sure it doesn’t shine too high.
  • Adjust screws:

  • Bottom screw in (clockwise) → lowers beam
  • Top screw in (clockwise) → raises beam
  • Avoid anticlockwise adjustment (risk of projector touching lens).


  • Refit grille, bumper, and any removed parts.



STEP 5: TEST & CONFIGURE

  • Download the following apps to control your headlights (ensure Bluetooth & Location Services are enabled):

  • Magic LED App → Select SP105E Controller
  • LED Lamp App → Use Search function (auto-connects)

  • It’s recommended to run Low/High beams initially to dissipate moisture.
  • If excessive moisture persists beyond 10 days of use, please contact LADS Lighting support.
