Headlamp weirdness

Post by Adamantium » Tue Dec 20, 2011 6:18 pm

Hi all,

Had a serious look at the lighting on my S2 for the odd night time driving that I do in it and I cant for the life of me figure out what's going on.

First of all, my car has the additional spot lights thats eem to come on with the main beam.

All fine I thought until looking at the beam when close to a wall. The rhs seems to be old school naff lighting with no focussed beam just a weird circle of yellow light. The lhs is a proper low beam of whitish light with a nice sharp cut ioff consistent with a proector lens.

Both lenses are projector but I can't figure out why they are behaving as they are.

I stopped the car today and got out to take pictures to find that in dip beam mode, the right main beam additional spot light was on, the right main beam light was on in the right lamp assembly but no dip beam.

On the other side I think only the dip beam was on.

Either way it's not right and I can't think of why. I took a picture, then turned the lights off and on a few times and now I cant get it to happen again.

I'll post the picture as I may have remembered it wrong.

Does anyone have any ideas?

Bad earth somewhere. Normally inside the headlight cover. Do your cover steam up?

which are the mains and which are the dipped in the headlight clusters? I'm going to guess the outer ones?

Well, that seems to be wiring issue with electrons flowing through the wrong devices! I would guess that a loom cluster has been disturbed at some point (any repair work been done on that corner?). I'm sure an auto electrician would sort it in minutes if he can get to the bits easily, (so it'll probably take hours.......)

As far as I know the driving lamps (lower middle) should be wired to come on with main beam so that all three units on each side are lit when main beam is selected. There might be a separate switch for the driving lamps so that you are able to turn them off if you want to.

What bothers me is the inconsistency.

On the drivers side the extra light is on, and it's as if the dip beam bulb has failed, but if that is main beam, then why isn't the other main beam central bulb on?

The drivers dip beam bulb is probably fine. Its earth is not, so is trying to find its way, via the earth splice for all the lamps and then back through the main beam bulbs positive connections to earth. Any auto electrical info says the steps to fix are, check live, check earth, check components, then check earth again.

Similar to when you are behind an older car, and all the lights in the rear cluster flash when side, brake and indicators are on, then all good when one of them is switched off.

Some cars clearly hate forced induction..........remove it and see how happy you and your car will be together .......forever


It's a love story Adam, a simple fix do it. NA Rocks :cool:

Jonny,

Since becoming a real man, I have only had one normally aspirated car. It was a 350 SLK. Something of a girl's car.

Don't tell anyone but it was the best car I'd ever had and probably still is.

The exige is not the best car I've ever had, but I think I can say without question that it is the most fun.
