Help - how to adjust headlights?

polo1.8t · Post by **polo1.8t** » Sat Jan 12, 2008 5:13 pm

Hello

Just fitted my GTi with HIDs and they're a little out of sink. The passenger's side is set slightly too high and the beam is rather scattered, could do with lowering this side quite considerably....any ideas as to how to lower and alter the beam pattern??? I did this fine with my Punto 5 yrs ago, but I can't even see how to adjust these headlights?

HELP!

There must be 2 screws on the top of the headlight?

On the 6n2 the one with the % beside it controls height, I turned it anti-clockwise for raise the headlight. The "Auf <-> Zu" screw is left and right. It's easy to break the mechanism so be careful

It's a job for a pro really, â‚¬40 where I live

But really you're asking for problems running 55w HIDs with a halogen reflector. They're just not built to control that intensity of light

oh no don't say that!

i'll have another look tomorrow on adjustment, thanks for your help!

Agreed theyre not built to handle, but if adjusted appropriately, the beam can be controlled. My 55w are on my main beams, 35w on the dipped. Its an adequate mix to say the least

I'm sure there are 2 different types of HID bulbs, one for people who have projectors like myself and one for people who don't.

I'm guessing that stops any issues with the beam pattern.

There are some with a reflector built on to only push light out one half of the bulb, like what ive got. D2S and D2R are projector designed bulbs, as they give light out the whole bulb.

on the site where I bought them from it didn't mention anything about this...what can I do, I can't send them back now that I've fitted them to my car, and I'm not going to change them back to standard...are you all certain that they're not built to handle this power?

If the bulb has a wire running up it, and a circular mid section its fine.

Theres no issue with the brightness - HIDs are 300x brighter than halogen bulbs, so excess light cant be avoided. You just need to make sure they are adjusted correctly - note this is a little lower than a normal halogen setting.

Well yeah, they weren't designed for all that power.

But all you have to do is get them adjusted to the point where you have a good beam pattern, and you're not dazzling other drivers. It's going to be harder than adjusting a 35w HID, but it should be doable

I still can't work out how to adjust the headlights themselves, any ideas how I do this? Have looked around the area for Auf & Zu as per previous post, no mention anywhere. Nothing stands out in the engine bay anyways. There is however, two different coloured (yellowy/green) holes which a philips screwdriver would fit down, with what looks like some kind of adjustment to the headlights...there is only two per side one looks as tho is for the main and one for the dipped beam...so may have a go at them perhaps.

Has anyone actually adjusted their headlights on here, that maybe able to help???

Two per side - one up and down one for side to side - have a tinker and see what happens

Be careful tho as they can snap if stressed!
