  • Technology

    LED

    LED bulbs offer high brightness and excellent energy efficiency, consuming less power compared to traditional bulbs. They are distinguished by their long lifespan and instant response, providing clear and strong visibility even in challenging conditions.
  • Type W21W, DRL, W3x16d

  • Color Temperature

    Colour temperature in lamps refers to how warm or cool the color is. 


    The warmth of light is measured in Kelvin; the lower the Kelvin rating, the more reddish the hues, and the higher the rating, the bluer the hues.


    Indicatively, lights with 3000 Kelvin are usually recommended for fog lights, lights with 4300-5000 Kelvin are usually recommended for driving lights, and from 6000 Kelvin and above are for a more distinctive style.

  • Voltage

    Voltage indicates the electrical current required for a lamp to function properly. Most car lamps operate at 12V, which is the standard voltage for most passenger vehicles. In trucks or heavy vehicles, 24V lamps are usually used.
