AIS (DCDRLH4) DAYTIME RUNNING LIGHT DECODER FOR H4 LED BULBS

DRL DECODER FOR DAY TIME HEADLIGHTS ''PULSED'' (DUTY CYCLE / PWM)
The DRL decoder will be used on the majority of vehicles 2006 and up, when high beams or low beams are used as "DRL"daylight systems activated by the car's computer. The cars's computer ensures that the voltage directed to the original bulb is provided by micropulsation from 0 to 12 volts as shown in the diagram to the left. It ispossible to check this micro-pulsationusinganoscilloscope. A regular multimeter would not be fast enough to see the reading so it would display an average voltage of 6 volts.

SPECIFICATIONS:

  • Use the decoder when there is flickering on"DRL"headlights. For optimum lighting stability in"Day Light" mode by regulating the voltage at 12 volts to avoid all flickering of headlights.
  • Stabilizes the output voltage to +/- 2%.
  • With connectors identical to those used by the manufacturers which allows quick and easy installation.
  • Operating capacity of 6-30v dc.  Water-resistant box superior to ip67 standards
