Bi-Halogen and HID kits

Featured Replies

The vRS has a bi-halogen light system and the standard lights are rubbish.

I have put my set of philips extreme's in and, well tbh they're not that much better. Plus I want the lights to match the white of the DRL's not slightly yellow like the philips bulbs.

HID kit's...

Now, I know they are like marmite on this forum, and I AM NOT looking for "oh, they blind children from 1000 yards because of the beam pattern"

If you want to post that, dont. Its been done over and over. Most of the bad press comes from idiots who dont even know that normal Halogen lights have a correct way around.

What I want to know is, if I were to use a HID kit, would I loose the function of my "main beam" lights?

No it's a bi xenon bulb then it's an h4 bulb that you need, bi xenon so have both dipped and High in one bulb fitted a kit the same to mates fiesta st, good job :)

Its H7 in the Mk 2 Fabia.

You will need a H7 Canbus system as well so as not to induce a bulb out warning light.

so ill still have the use of main beams? how do the projectors work then? is it just a case of changing a lens on to adjust the beam from low to high?

i want green ones for shows!

An OE Bi-Xenon system uses a shutter system in front of the 'bulb' this gives you the cut off when on dipped beam and moves up to enable the distance of full beam.

However halogens that use a single lens for dip/main beam normally just use a dual wattage bulb - completely different.

So a 'normal H7 xenon kit will not work, you specifically need a Bi-Xenon kit.

Be prepared to change them back to halogens come MOT time however as the MOT will soon be checking for aftermarket kits without the washers / self levelling.

I'm not going to go on about just how bad after-market HIDs are - only you can decide if you want to be selfish enough to potentially blind oncoming traffic.

The big issue is their legallity.

By all means fit them, but come January they will be an MOT failure and police have been training to spot vehicles with these "kits".

Just so you're fully aware of the whole implication in fitting these so called "upgrades".

I must admit I bought the Philips bulbs also and was disapointed I as expecting them to be white like the DRLS.

Hids are excellent when used properly :) I didn't realise you could get h7 as bi xenon but you obviously can I would kno if I had mk 2 fabia lol :(

Likewise.

I have ordered some Orsam cool blue hyper plus h7's since I'll loose the main beam function of my lights with a HID kit. They are halogens at 5000k apparently.

The mk2 vrs does not use a bi halogen set up.

In each headlight unit there is a projector which is the dipped beam, and this uses a single filament H7 bulb, there is also a reflector which is the full beam/light flash, and this uses a single filament H7 bulb.

I have converted my dipped beams to HID's and the light output is amazing.

There is some question about the new MOT regulations but that will not concern you for 3 years and in any case if there is a problem it will be an easy matter to change back to bulbs.

sorry just re read the first post i mis read it sorry :(

I think the light set up for the MkII is now going to be split between the Non black pack and black pack cars.

As the Silver light pack I still say looks like it was designed from day 1 to be a xenon setup.

That's interesting...

I have the black pack, so I have only one H7, single filament bulb in each side. When I use low beams it looks like the light is bent when I park up against a flat wall, but when I put the main beam on the light pattern changes to two large ovals, and the projection at night is superb btw.

This got me thinking that the low beam is just a mirror or some sort that bends the beam down, and when you engage main beam moves out the way. There is a fairly loud click if you flash someone, like something is being moved very fast on a shutter.

I just dont want to fork out ~£50 to find out I wont have the main beams. Expensive mistake.

Whilst it might not affect the MOT until the car is three years old, you are increasing the risk of being stopped (its easy to spot aftermarket HIDs in the dark as cars come towards you) and you will fail a roadside inspection and they could put a prohibition notice on the vehicle, meaning you cannot drive any further and the car must be recovered from where it is. You may get lucky and get a defect rectification notice, which gives you 7 days to fix the issue and get it stamped by a MOT testing station.

This is the department for transport's stance:

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.

In summary, you can retrofit HID Kits but do it properly. Which nobody EVER does because it would cost a fortune.

One person thinking of retrofitting a HID kit saying "I know what everyone says, I'm doing it anyway" will always get told by members of this Forum to think about what they're doing. Why? If someone said there going from A to B but they're going to do it at 120mph, people would say it's illegal, unsafe to do so and puts others at risk. Same sort of logic applies here.

We can't stop you doing it but we'll do our best to give you the straight, honest facts :thumbup:

Well said, Reavenger!

I know I'm bumping an old thread but I couldn't find the right answer. I have Skoda Fabia mk2 2009, the the BENDING BI HALOGEN headlight in the picture bellow.

What's the consensus, will a quality H7 LED (NIGHT BREAKER H7-LED GEN2) work plug and play, as in will the projector focus the light correctly and the main dipped and full beams work, or will it not?

As far as I can tell (I havent fitted these to my car so pinch of salt) if you are using gen 1 / original osram LED you need this adaptor for the projector light on a mk2:
OSRAM 64210DA01 LEDriving Adapter for Night Breaker H7 LED; Lamp Holder, Silver : Amazon.de: Automotive
Link to german amazon as you cant seem to find them here.

part number is 64210da01

If you are using the new gen / gen 2 which is the thinner body of LED I think you use:

OSRAM LEDriving Adapter 64210DA01-1 Adapter for Night Breaker H7 LED; Lamp Holder, Silver : Amazon.de: Automotive
which is part number 64210DA01-1

Id love to let you know how they work but ive ordered 64210DA01-1 by mistake! Ha )
