LIGHTING


  1. General


    1. The Light Emitting Diode (LED) headlight system is used.

    2. The LED headlight system uses LEDs as its light source. This system consists of LEDs and headlight light control ECU sub-assembly RH (LED driver module).

    3. The fail-safe function is provided in case that problem occurs in the headlight system.

  4. Construction and Operation


    1. LED Driver Module


      1. The headlight light control ECU sub-assembly (LED driver module) illuminate the LED used as a light source for the low beam headlight, high beam headlight, clearance light/daytime running light, front turn signal light and front side marker light.

      2. The light control ECU sub-assembly (LED driver module) illuminate the LED used as a light source for the high beam headlight.*

      3. When the low beam headlights/daytime running lights or high beam headlights are illuminated, a constant current flows to the LED to instantly stabilize the headlights. Also, changes in the LED current due to fluctuations in the voltage are reduced to prevent the lights from flickering.

    2. Headlight Assembly


      1. Through optimization of the shape of the lenses and reflectors inside the lights, a large illumination range has been achieved.
