Hi, Neil and Mathew have said all the important stuff but having kicked off a similar discussion some time ago, Ive been doing some testing of the "new" extra efficient normal bulbs which claim to use Xenon rather than other gases. These are onsale everywhere now and I believe are totally legal. The power rating is still 55/ 60 watts for the H4 and 55 for the H1. Some are being advertised as 50% + light output and others up to 90%+ light output.Certainly, these bulbs are better in a standard headlamp unit rather than the lesser forms.They cost up to £20 each but are available for more like £30 a pair of H4. Phillips Osram, Halfords all do them. I have noticed some statements about these bulbs having a coating which filters light that can affect the plastic covers used on modern headlamp assemblies.I'm guessing that there has been a problem at some stage where similar bulbs have caused the plastic to go opaque. When I tried the HID Xenons in the standard Fiesta Mk 2 headlamp shell (35 watt H4 bulbs) they were very bright but the scatter particularly on dipped beam was not good. The actual mechanics of the HID bulbs are questionable as H4 styles. Some have a HID for dipped beam and normal for main but there are several variations. All of the aftermarket HID sellers that I have found all put in a clause saying off road use only somewhere in the small print. I was pointed to the Government website where there are staements about aftermarket HID use. I have also tried an H1 version in an Alfa with projector lenses. This combination gives an extremley sharp cutoff and obviously a very bright light. I understand from a MOT tester that the guidance on colour is that any blue forward lighting is a MOT fail. It's interprative and 6000 kelvin may cause discussion. Above that it is almost certain to be considered too blue.
