Halfords do a range of suitable bulbs (Type H7). I went for Zenon 6000K bulbs to replace all 4 (high beam/low beam). These have a slight blue effect. The higher the number (ie 8000K), the brighter they are but my choice was twice the brightness of the standard ones. They are a devil to fit, so get the Halfords man to fit them for you! Good luck!
It is my understanding that the K (Kelvin) is a color measurement not brightness. The higher the K number the dimmer and bluer to purple the lights become. Thus the 3000 and 4300K bulbs are brighter.
Correct me if I am wrong.
I have HID (4300K) lows and Sylvania Ultras for the high beams and the difference is very obvious. The Ultras look like the yolk sitting above the white of an egg compared to the HID's when shone on a wall.
I have 3000K spare bulbs but I have not compared them to the 4300K's yet.
