The KATUR H4 LED Headlight Bulbs are designed for drivers seeking to upgrade their factory halogen output to a brighter, more efficient lighting system. These bulbs offer a significant boost in visibility with 30,000 lumens and a crisp 6000K white light, making them ideal for long-distance nighttime driving. While they are engineered for a simple plug-and-play installation, users should verify their vehicle's specific headlight housing clearance due to the integrated cooling fan system.

These bulbs are designed for performance, but regulations regarding LED headlight retrofits vary by region. Please check your local laws before installation.
No special tools are generally required; they are designed as a direct plug-and-play replacement for H4 sockets.
If your vehicle uses H4, HB2, or 9003 bulbs, these are physically compatible. Always check your vehicle manual to confirm the bulb type.
Yes, but ensure there is enough space between the cooling fan and the cap to allow for proper airflow; otherwise, the bulb may overheat.
These bulbs produce a 6000K light, which is a bright, clean xenon white.
No wiring modifications are required for standard installations.
Although these are 98 percent CANBus ready, some vehicles may require an additional anti-flicker decoder module to bypass the computer's bulb check.
LED bulbs are polarity sensitive. If it doesn't light up, remove it, flip the plug 180 degrees, and reinsert it into the socket.
Check that the bulb is seated perfectly flush in the socket. If seated correctly, adjust your vehicle's headlight aim using the adjustment screws on the housing.
Installation is designed to be straightforward: turn off the engine, remove the factory bulb, and insert the KATUR bulb into the H4/HB2/9003 socket. Ensure the cooling fan has enough clearance to rotate freely and that the dust cover of your headlight assembly can still be closed properly. If the beam appears scattered after installation, ensure the bulb is fully locked into the socket. To maintain performance, avoid touching the LED chips with your bare fingers, as oils from the skin can affect light output and longevity. Periodically inspect the rear cooling fan to ensure it remains free of heavy dust or debris accumulation.
