How to raise the Mazda Xenon headlight for better visibility
« 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



anything else, let me know  ;)

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?
