Has anyone tried these.
Do they fit.

if the led is housed at the same dimension from the mounting face as the normal h4 bulb filament then they should be ok.

Are they legal? As per HID retro-fitted bulbs?

Are they legal? As per HID retro-fitted bulbs?

At the risk of inviting any more 'daytime TV' jibes, 'Wheeler Dealers' had to put a notice on one of their old programmes to say that their fitting of HID bulbs to an old Lexus (in the case of this particular programme) wouldn't be legal.

Yes - I saw that programme. They said that the the use of HID bulbs should be with a complete custom-made headlamp fitting - and not retro-fitted in the existing headlamp housings - or words to that effect. This is presumably to avoid mis-alignment/ bad adjustment of the bulbs and dazzling other road-users

Here is the DOT's view of them.

The H4 LED bulbs I have seen looked great in colour when on (bright white) but must have only been shining 15ft. Wasn't drivable at night. Standard bulbs went back in.

The key word in the whole of the paragraph is in RED below, despite the DfT publishing their 'view' in May 2010, it still remains untested in law

In the Department for Transport's (DfT) view it is not legal to sell or use after market HID lighting kits, for converting conventional Halogen headlamps to HID Xenon. If a customer wants to convert his vehicle to Xenon HID he must purchase completely new Xenon HID headlamps. The reason for this is that the existing lens and reflector are designed around a Halogen filament bulb, working to very precise tolerances. If one places a HID "burner" (bulb) in the headlamp, the beam pattern will not be correct, there will be glare in some places and not enough light in other places within the beam pattern.

The following would be a better option: http://www.ebay.co.uk/itm/1118278473...%3AMEBIDX%3AIT and there a number of such units on sale in both LHD and RHD beam patterns from a variety of manucaturers

Is it just me or do most HID headlights tend to dazzle? I don't think the DOT rules have caught up with the current headlamp technology where the amount of light bears no relationship to power (wattage). I used to use 80/100W bulbs for road rallying and were marked not for road use, but modern headlights are much brighter. Has anyone seen the adverts for the Laser Lights option from BMW? Not sure how such powerful lights can be road legal.

But i started this about LED, not HID
