Koplamp

Koplamp is the Dutch term for the front headlight of a motor vehicle. It is the primary source of forward illumination and helps make the vehicle visible to other road users. Koplamp units work in concert with other lighting systems, such as daytime running lights, fog lamps, and turn signals, and are distinct from rear lights and indicators.

Most headlight systems include a low-beam setting for regular nighttime driving and a high-beam setting for increased visibility at greater distances. Some vehicles also feature adaptive or dynamic beam systems that adjust the light pattern based on speed, steering, and oncoming traffic. Daytime running lights are often required or standard in many regions to improve daytime visibility.

Technologies used for koplamp assemblies have evolved significantly. Halogen bulbs were common for many years, but modern vehicles increasingly use LED or HID (Xenon) lamps, and a few high-end models employ laser-based lighting. LED headlights are popular for their efficiency, longevity, and compact design; HID lamps can produce very bright light but require ballasts and can take longer to reach full brightness. Adaptive or matrix headlamps use sensors and actuators to optimize the beam pattern and reduce glare for oncoming drivers.

Regulatory standards govern koplamp design and performance, with regional variations. In Europe, ECE regulations specify beam patterns, color temperature, and mounting, while North America follows SAE/NHSTA guidelines. Proper alignment, brightness, and color consistency are essential for safety, as misaligned or poorly aimed headlights can reduce visibility and dazzle other drivers.

Maintenance generally involves cleaning lenses, inspecting for condensation or damage, replacing bulbs when needed, and ensuring correct alignment and aim.
