Customers that are looking to greatly improve visibility but also achieve that distinct hid  blue are generally recommended a 6000khid bulb. We believe this is the best compromise as the 6000k is incredibly bright but also has that exotic hid bulb look.
     Color and temperature are two terms that you will inevitably hear when contemplating your HID kit purchase. Color is self explanatory but temperature relates to more than just color. Lumen output (brightness) varies depending on which color (temperature)HID bulb you choose.
     Another example would be a 4300k compared to the 6000k. The 6000k is a lighter blue but brighter than the 8000k which is deeper blue but lower lumen output.
     As temperature increases from ~4000k brightness will decrease. For example, the brightest hid lamps we offer are 4300k which are the brightest OEM white available. As you increase temperature, the lumen output (brightness) will decrease..
