In contrast to the misconception that color temperature is a rating of the brightness of the bulb, the higher the color temperature, the less usable light output you will obtain. A 6000K bulb produced 15% less light than 4300K. Pure white light is almost invisible during inclement weather. Headlight rated at 3500~4000K actually produces the best usable light output favored by human eyes. FIND YOUR FITMENT: Not sure the correct fitment for your vehicle?
