Xenon upgrade on a p38

Hi,
I bought a hid hi/lo beam xenon light kit, I just heard roumers that it wont work it messes with the computer, is this true, or is there a way of not knackering my car.

thanks for looking


2001 RANGEROVER P38 4.6 HSE
NEW ENGINE , OIL PUMP CLIMA ETC GEAR BOX, ALL COMPLETED BY LANDROVER EXCELLENT CONDITION
DRIVES LIKE IT SHOULD AND DOES NOT OVER HEAT LIKE MY LAST ONE, LOL

The HID's draw less current than normal lamps so the BECM logs a lamp failure. You can fit resistors in parallel. HID is now Old Tech, LED headlamps are the in thing though for the speed of the P38 the normal lights are more than adequate IMO.

Can't imagine the cost of full led lights !!! Led side lights I understand but hid is a lot brighter than led at this moment in technology
And a damn sight cheaper.

You could just live with the lamp error ?
Oh and remember to swap back old lamps when you go for an MOT otherwise it will fail lol

Got factory fitted xenon on mine and they beat any halogen lamp

I tried this on mine. Overcame the bulb failure issue easily but had weird faults coming up on the dash when I turned them on and when I went from dip to full and back. I can't remember everything but when the I saw the SRS flashing up I decided quickly that I wouldn't chance the BECM. I went back to 'slightly' overpowered halogens.

theres a diagram on this link of wireing here... http://www.landyzone.co.uk/lz/f10/h-i-d-s-51150.html

Just put Nightbreaker Osrams in mine and they are great, dipped beam is the only real issue and they have solved that.

bet yours kill your battery if left on

what you got then ??? 100w H4's ?

Strobes, smoke and a mirrorball

On full beam ?

4 x 150w sealed beam units

2 x 55w HID's

So 3,168,000 million candlepower at 55w draw from the 100amp alternator


Then add on whatever the 2 x 55w 100% brighter bulbed halogens and radio so I'm probably looking at a max draw of 70 amps which is near the top end of the alternators comfort zone but alls well so far Might double alt it if I get bored

well that is quite a setup, was going to say about your alternator, is it the standard OEM or have you upgraded it to cope with the extra load ?

bet those 55w HID kill ur eyes (and other road users) ! lmao ! 35w are bright !

haha thanks, took a while to fit and I've now got to get a peak cap style thing for my light bar to stop the windscreen glare from the end two roof lights, means I can point them fully down the road rather than at the upward angle they're currently at

My bad I meant to put 50w HID's and yes they do, I adjusted the angles with them on at night on the drive and they was blinding from point blank

Standard 100amp Denso unit cos I've got aircon but thats rarely used as I prefer driving with windows down

a p38 fitted with hid headlamps will not fail the mot. as it has self leveling suspension (unless it has a crappy coil spring conversion) and headlamp wipers.
mine had hid lamps fitted when i bought it yes you get bulb failure warnings but you get used to it!

Yes but as far as I know you also need projector type lenses not reflector lenses like the p38

Otherwise the light beam is scattered all over the place hence an MOT fail

And you need self levelling headlights not self levelling suspension lol

Sorry Hippo I think if you look that self leveling suspension is OK, self leveling lights only needed with cars that don't self level.

Oh right
Well I'm not 100 percent on it

Either way if your facing up a hill your lights will be very high where as on my l322 the lights aim down while going up the hill. The suspension doesn't adjust how ever

Also why would they fit self levelling lights on the l322 with self levelling suspension if they weren't needed ? Lol

If you are going uphill, apart from at the brow of the hill, surely you need your lights illuminating the road ahead as normal? The suspension will still be level with respect to the road so the beam angle to the road should remain constant.
Seems to be overkill if the light self level on a car that has self leveling suspension and if they point down when going up hill do they point up when you go down hill? Either way sounds fecking stupid, the last thing I would want is a reduction in lighting range just becaus I'm going up hill

Interesting one ah lol

I know what you mean, the adjustment is only very minor, you don't notice any reduction but you can see that the slight adjustment stops the beam shining in the faces of oncoming drivers

Clever stuff 😉

also mine was moted with hid kit fitted and the beam pattern is fine
