Title: How to raise the Mazda Xenon headlight for better visibility
Post by: sk4tec on April 29, 2007, 03:23:30 PM
This is the first car I've owned with Xenons. When doing my research for the 3 Sport, I read on Whatcar.com of owners who didn't rate the Mazda Xenons. They said they didn't have as much range as they expected. I found this as well.

I drove my 3 on an unlit motorway and the range of the lights is quite short compared what I'm used to. I've had a look under the bonnet and it looks to me the inner light is the side light, this has a conventional screw adjustment.

The outer light appears to be the Xenon and you can make out from the shape that there is a motor behind the cover - I presume this is the self level motor unit.

Is there anything that can be done to extend the range of the Xenons? Or is this how all Xenons are, erring on the side of not wanting to dazzle on coming cars.

I agree the range could be a little better, but when you have the luxury of Xenon's and the quality of light output, I can live with it.
The only thing that annoys me is the "Yellowness" of the main beam in comparison. ** Thinks, must do something about that**

I find is not a problem on motorways but not so great on county roads. I did notice they are not bi-Xenons like you get in say BMW's etc.

I don't mind too much as I was expecting this problem. I seem to remember thinking the same thing in my mates Honda S2000 - the lights in that were a little short.

I tweaked the lights in my last car to raise the light level a fraction, not an option with this car.

you can manually adjust the range of the headlights.. thats what i did.. and now i can see so much further, even though i have the halogen projectors.

but i must say that my aftermarket HID kit seems to perform so much better than the OEM xenon lights.. i'll post some projection pics on later..

but for now, you can check the attached PDF for help how to level the headlights manually.. :)

I wish I did'nt have the things on my sport, they are trouble (in my opinion) the dip range is poor and the cut off too sharp which accentuates the darkness beyond. Nearly all of my driving is out in the country with no street lights. If a Zenon bulb goes it will cost me 300 quid, not a tenner from Halfords...and if they are supposed to last the lifetime of the car, why have I heard of people having to have them replaced, at their own cost.
Rant over!! :D

you can buy the bulbs cheap from HID planet forums, depending on your luck, you can get new ones, but most will be used bulbs still in good working order. I have 2 pairs of spare Xenon D2S bulbs unused which i was gonna use in a project, but no longer need them now..

let me know if you're interested..  ;)

Thanks for the pdf but to me it only covers non Xenons. On the Golf mk iv the baseline adjustment was done in the ECU.

but on the mazda 3, it covers both Xenon and Halogen headlights... they both similar just different shape and different projector shield.. give it a try though, or ask your dealer to do it for you to your required level.  :)

I noticed on my headlights the marking '1,0'. In most of my cars I remember seeing '1,3'. I don't know what metric this measurement is in but to me it seems Mazda have decided to be more cautious with their vertical aim.

I'm still a but confused if the plastic screw behind the headlight adjusts the whole light assembly or just the halogen side light? I've adjusted the lights on my last few VW's but they were conventional headlights. Anyone explain this?

the screws raise the whole assembly.. ie the low beams and the high beams together.

so yes you just need to adjust the inner screw to raise the low beam.

where abouts in the country are you? i dont mind coming down to help you out :), thats if you're not too far away..  ;)

ok this is fairly easy. just make sure that its a bit dark so that you can see the level of light projection against a wall or fence. while turning the screw, keep an eye out for the level of the light going up or down. You have to turn the same screw on both headlights individually

See when the lights are fitted and you look under the bonnet at where the lights are you can see a white plastic bit that has a hole ofr a philips screwdriver( you can see the white bit on the pictures above) Put ascredriver in that and turn thats the master screw for the lights to go up and down. but you can do it your way to ;)

I've been struggling with the range of the Xenons on dipped too - coming back from the SW meet yesterday was hard going especially in the torrential rain.  Anyway, took it to a mechanic mate of mine who stuck it on his MOT ramp and said the lights were set so low they would fail the MOT.  He adjusted them and put them up to the top legal limit.  Driving home was much better but I had a warning light come on saying they were adjusted too high!  Lol!  Anyway, I've lowered them a little, the l warning light's gone off and they're much better :)

Didn't have this problem at all on our 6.

Sorry to drag this up.. but i agree the xenons are set stupidly low... as it is i rekon the beam cuts off not even 5m away from the front of the car, which makes it essential to use full beams on unlit roads round here.

Si68, did your MOT man adjust them with the screwdriver?

I don't think Si has internet access at the mo.

I adjusted mine with a screw driver. Its easier if you take the fuse box cover off. The screws are quite stiff to move. Mark the screws up with a line of white enamel paint and remember how many turns you make. Keep them even both sides. U'll only need 2 turns max and fine tuning with 1/4 and 1/8th of turns.

Remember that as they are Xenons they can't be run at the same range as regular lights. You should be able to see the cut off on the road. Don't raise them too high.

Finally back online - Orange!!! Grr!!

Yes, my mate used a screwdriver to do it.

Some dealers know about this, perhaps it was done as PDI???

Hi MisterG, the short range problem was the first indication on mine that the levelling auto sensor/motor was about to pack up....had them adjusted at the dealer not knowing this, then a week later they were too high. Had the motors renewed under warranty...ok since (fingers very crossed)

Hmm but this surely shouldnt be the issue on a brand new car??

Probably not an impending component failure as it's a new car (congrats by the way) I would go along the lines that they have not been set correctly.
As your car is only a matter of weeks/days old I would definately pay the dealers a visit and ask them to check it out.

Well, after comparing with another car (albeit a skoda) the lights are defo too low... travelling down a unlit part of the M62 made me realise that the range on them was terrible.. the distance of them was only lighting up the distance between 2 catseyes (ie i could only see one lit while the other passed the car)

Ill give the dealer a shout tomorrow as i also have the rattly scuttle cover problem

Ive just had "a moment of clarity"  ;D

I bet that when the Aero kit was designed, they didnt think to sort out the headlight levelling... IE,  because the suspension is a couple of CM lower the headlights think the back end it heavier loaded than it is, so angles the headlights DOWN more!.. now it makes sense LOL!

Am going to get some Rallye main beams and diadems ordered too.. the main beam isnt great either  ;)

Grrr.. useless dealer!
they have adjusted them, but different amounts so one is higher than the other... ill have a go myself at the weekend!

Keep in mind the top of the beam curves, so rather than a solid beam of light from left to right you'll have two arcs with a dead spot in the middle.

As suggested park opposite a wall. As far as Xenons go, the beam throw is poor, but its nicer than regular lights.

Yeah, but they have the same "step" in the middle that lines up... think ill raise the other one to match the high one which i think is about right.

I took my MPS to the dealer this week about the Xenons. They agreed that they looked low.

I had to leave the car with them for a day while they worked out how to adjust them (http://www.mazda3forums.co.uk/Smileys/default/rolleyes.gif) however, they did manage to raise them up and they stretch much further up the road than before, I was actually able to drive at 70 on the dual carriage way rather than 55/60 before because I could only see a short way in front.

I guess I should have taken some before and after pics. Previously they stopped about 1 car length away with a very defined cut-off.

Took our 05 plate Sport for an MOT the other day and lo and behold it failed on headlight aim. Now this being our local garage which we tend to frequent rather than the rip off main dealer,they put their hands up and said they did not know how to rectify this problem so the missus ran home and unearthed our ebay workshop manual cd and returned with the relevant info albeit I think its for manual adjustment not the self levelling nonsense that we have on our sport, ,lights adjusted and pass certificate issued.This was after a call to Mazda who informed us that we would have to book the car into the main dealer where it would have to be hooked up to their computer for roughly an hour to fix the problem,obviously at our expense.
Having said that I've not been out in the dark yet but I can concur with previous posts in that I always thought the dipped beam spread was rubbish bordering on dangerous.

do you know - guys - if OEM xenon headlamps can be adjusted not in height but laterally/left-right? I explain, I have a LHD 2007 Mazda3 GTM (equivalent of Sport trim). I would like to import it so headlamps need to be modified.
thanks

Hello, thicko of Edgware here!
I've just fitted some Hids (6000K) 35w which I got off of fleabay, good quality and fitted in no more than 30mins - great!

BUT, very poor aim, I've twiddled with the White plastic knobs which have the cogs on them(?) suppose that's where the manual adjuster switch in the cabin works from and, they were a bit better but, it's that photo attached by Neeldub, the gold coloured bolt he has circled as "Turn Anti clockwise" and then the sort of hole where the screw driver goes - as I said I'm thick can someone explain which I need to used, do I loosen the gold bolt first then twiddle the screw or am I just Mad?

The spread is far too low, the right hand beam is a bit higher than the left but, bleeds a bit too much to the right of the car, the left is just too low, if it was raised it would probably be right, it could possibly need to come left a bit to light the gutter a bit more.


The car is a 56 plate 2007 ts auto sedan.


Thanks for any help.

Hey thanks for this - keen to do this as mine are a bit low IMHO. They pass MOT (though the first ever MOT they didn't due to low aim - this was before my time) - but I need some range!
