Is it me or is the standard lighting system crap? well i upgraded my bulbs when i first got the car and on the duel carriage ways etc i probably cant see no more than 10 meteres in front of me regardless of how high the beam is on the switch inside the car, it seems like it needs to go higher!

Is there a way around this or is it a case of an upgrade?

Now for a bulb upgrade which should be upgraded too? Philips, osram?
i would like exact products please, are the xenon style bulbs the best? or like these halfords 80% more light etc any good?

What benifits will i see from a HID and is it legal to install them in any car?
is there a certain amount of brightness you aloud by law? i.e 6000k?

many thanks guys if you can find links to buy the HID or bulbs wud be appreciated

il give you a boring answer

Are they legal and pass an MOT? - Well according to the people at VoSA, after market HID's fitted to vehicles is not allowed, due to the headlamp lens being designed for Halogen bulbs.
Some people including myself have had them in when an Mot was or is undertaken have been check for brightness/alignment and have passed the Mot/VoSA check, in otherwords they are a VERY grey area where no bulb will illuminate brightly.
Iv got 6k on mine and its a nice bright white, the light it gives out is so crisp and clearn, il never use a normal bulb again!

Fact sheet: Aftermarket HID headlamps
December 2006

In the Department's 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 is the legal rationale:

The Road Vehicle Lighting Regulations 1989 regulate the situation in the UK.
Under these Regulations, HID/Gas Discharge/Xenon headlamps are not mentioned and therefore they are not permitted according to the strict letter of the law.

However new vehicles have HID headlamps. This is because they comply to European type approval Regulations. The UK cannot refuse to register a vehicle with a European type approval. These are to ECE Regulation 98 (for the HID headlamps which are tested on a rig in a laboratory) and ECE Regulation 48 (Lighting Installation on the vehicle).

For the after market, a used vehicle cannot obtain type approval because it is only applicable for new vehicles. However we feel that saying "HID is banned in the after market" would not be reasonable. Instead we should make analogies with new vehicles. It would be reasonable to require HID in the after market to meet the same safety standards as on new vehicles. The same level of safety should apply.

Therefore a HID headlamp unit sold in the after market should:

1. be type approved to ECE Regulation 98 as a component.

2. when fitted to the vehicle should enable ECE Regulation 48 to be complied with (although no government inspection will take place).

3. Comply with RVLR as far as "use" is concerned.

In practice this means:

1. The headlamp unit (outer lens, reflector, bulb) shall be type approved to ECE 98 and be "e-marked" to demonstrate this. That can only be done by the headlamp supplier - Hella, Valeo etc. who must test the headlamp in an independent laboratory.

2. Once fitted to the vehicle it must have headlamp cleaning and self-levelling (which can be for the headlamp or can be in the vehicle suspension - some expensive estate cars have "self-levelling suspension" and that is adequate). Also the dipped beam must stay on with the main beam.

3. The headlamp must be maintained in good working order, kept clean, and aligned/adjusted correctly like any other headlamp.

Under the Road Traffic Act 1988 it is an offence to supply, fit or use vehicle parts which are not legal.

In summary it is not permitted to convert an existing halogen headlamp unit for use with HID bulbs. The entire headlamp unit must be replaced with one designed and approved for use with HID bulbs and it must be installed in accordance with the rules stated above.

Basically Hids dont actually give off any better light than the normal halogen bulbs...

The way they work is they burn brighter(using electrodes rather than gas filled) wich produces a purer light which allows for more to be transfered for viewing..

Stay clear of So called Xenon Bulbs, they are still halogen filiment bulbs, with xenon gas, and as such wont give the same level of viewing distance as pure Hids will....

Better to lay out the initail cost of the hids.

Oh and 100w are illegal
