Apparently, if you go for the more expensive twin-filament bulb types as opposed to the cheaper single filament with moving shroud for hi-lo, this gets around that issue. It also means that should one blow, you don't loose hi and lo together on that side. Have a look at hid-direct on google, sorry I can't remember the exact web address. Badger.

They allegedly arc straight up, allowing the flash function to operate as normal Dave. I'm considering fitting them to my 110 which has 4 spots on the roof and another 4 in a pod on the bonnet - all wired via relays to flash with the high beam, so no probs there even if the HID's don't arc straight up.

> They allegedly arc straight up, allowing the flash function to operate > as normal Dave. Mine flash brightly when 'struck' then gradually get up to full wick in about a minute. But my experience of this type of lamp in film use is they don't like being switched on and off rapidly - as you might do when flashing. They might possibly protect themselves against damage by shutting down but then you've not got a flasher.

I'm well impressed with mine which were bought off ebay a couple of years ago for just over 100 quid including postage - and they've got cheaper since then. I ordered 4300k ones so they didn't look too blue and although the colour rendering is poor (rear number plates look slightly green) they give a decent light for driving - better than the 100w tungsten they replaced.

The ballasts on the set I bought have rubber seals everywhere and the documentation supplied suggests they are water resistant.

Pantelis Giamarellos - 27 Dec 2007 09:09 GMT People Hi,
Proper HID kits are very effectively protected from water or humidity.
As for how sensitive they are to a bumpy ride it is enough to say that they have no filement and therefore the light emiting elements quite simply are immune to vibration. This does NOT apply of course to the moving focusing center type of bi-xenon lighting elements ("bulbs"). But the proper twin "bulb" type for H4 hi-low "lamps" should not have a problem.
The ballasts are a different story and I guess it mainly has to do with the quality you pay for.
Just remember that proper HID lights are self leveling and also come with light cluster cleaning devices (water spraying jets or wash/wipe).
Fitting them to a P38 should not create a problem though since the self levelling suspension should (in theory) keep the light pattern where it must be so that it does not blind oncoming traffic from the other direction and wash/wipe was usually fitted from the factory (at least here in Greece)
Take care and Happy Holidays Season Pantelis

Not once I have had a problem. The main things with P38's are lack of maintenance due to some fool buying a car they expect to run forever for peanuts. How many BMW's run forever without servicing?
FFS, my wifes VW EOS needs a new gearbox at 7000m & the automatic Touareg she had needed a new gearbox every 300 miles. That got binned, very quickly.
I have sussed the P38 bugs, they tend to be silly sensor orientated things, once replaced they tend to be fine.
Watch this space ;)

How many BMW's run forever without servicing? The EAS is well known to be very unreliable, if you haven't had a problem yet, you soon will. Maintenance has nothing to do with it, there are no parts on the EAS that you would expect to change at a service, with the exception of the inlet filter on the compressor perhaps. How many BMW's need recovery to the dealer for a fault reset every time they have a minor electrical niggle?

Not the same. I very carefully worded wot I wrote... ie. the headlight units themselves adjust rapidly to the attitude of the vehicle so that the lights don't dazzle oncoming vehicles when you hit a bump.
Watch the head lights of a car with HID lights when they switch the ignition on and you'll see the units go through a calibration cycle.
I'll admit to not being 100% sure that it would be "illegal" to fit HID bubbles without the appropiate self leveling units, just a heads up. With a lot of things you can buy for cars just because you can buy them doesn't make them legal for road use.

Seems if you have self levelling suspension and headlamp washers aftermarket ones will pass an MOT - provided the beam pattern is ok on the headlamp alignment tester. My SD1 was fine. But it also has later headlamp units not for an SDI. Of course it will depend somewhat on the individual tester as all such things.

Only illegal insomuch as a violation of type approval for the vehicle and Construction & Use regs.

Headlamp wash is not an MOT testable item, so wouldn't be a cause for an MOT fail on a vehicle equipped with HID's. Nor is the auto lamp levelling checked. If the lights work and pass the beam test, then it's a pass. A scrupulous tester may issue a pass and advise if he realises they are HID and don't have wash/levelling. Badger.

Austin Shackles - 27 Dec 2007 18:55 GMT >I'll admit to not being 100% sure that it would be "illegal" to fit HID >bubbles without the appropiate self leveling units, as far as I know, yes, it is. That doesn't stop people.
there's no good reason for 'em, either. Ordinary 55W halogens are plenty bright as dips, and having anything brighter is in fact counter-productive. Most modern dip lights are brighter than they need to be and cause unnecessary dazzle, making it very hard to see unlit objects.
As for main beam, if you haven't got enough light for high-speed motoring, a pair of decent spots makes a lot of sense, rather than making the existing lamps brighter.
One mod I do find very worthwhile, and that's arranging for the dip beam to be on at the same time as the main beam. This can be done with one or two relays, depending on the vehicle. All you need is a supply to feed the dip beam, NOT running through the normal light switch, triggered by the main beam.
When on main beam, the dip beam fills in the bit fairly close to you, especially when going over crests in the road.

It may be worth checking your lights out carefully. The light output of our P38 is excellent, more than adequate for anything it could possibly be used for.

The idea came from a Mk II granny, which had its headlamps wired like that from new. Took me some careful study of the wiring diagram to work out that it wasn't a fault, when I first noticed what it was doing.
