UK SG9 XT - HIDs to Halogen headlights, is it possible?

2928 Views 13 Replies 5 Participants Last post by  Dabooka
My motor has just failed the MOT on poor lights (no pattern; out of alignment and too low).

As one unit is completely borked and the other one clearly isn't moving correctly (I know the rear self adjusting unit is missing) I'm looking into replacements. I am thinking it may be simpler to downgrade to normal halogen headlight units, has anyone done this and is it even possible?

The HIDs are are as hell on the used market anyway, new ones I'm not sure are even available and I'm not certain it'll fix the problem anyway. Halogen units seem easier to find.

Hi chaps, I trust you've all had a nice Christmas. I can't believe it's been two months since I posted this (!) but to be honest it's just been sat on the driveway since failing as I've had too much on to even contemplate getting it sorted. However I have a week off so need to decide the future.

Right, the deal with the headlights is this;
  • The nearside (left) is borked. It's not cloudy in a way that can be polished out with a kit as it's knackered on the inside. Despite resealing the unit, it still has condensation forming and appears cracked after a shunt of some description. I am assuming over time the water has heated up from the lamp and caused the distortion of the plastic as it clearly been a long term issue.
  • The offside (right) functions normally but doesn't move. I have noted that the rear level sensor is missing completely, and I probably need to check the front one too once I find out where it's located.
  • There are no error lights on the dashboard relating to the lights.
I appreciate after looking replacement units are rare as hen's teeth hence wondering if I could just downgrade to halogens. I guess I'd have to manually adjust them and accept I couldn't control them from inside although I don't see that as much of a problem.

Once i get this resolved I can move on to the next problem which is to get the secondary air pump deleted and then I should have an advisory free motor. Which would be lovely!

Crikey TMX, what a fantastic response!

I'll have a look at those links later. I've tried a few breakers with no joy so far; either sold or equally as knackered as mine. One even sent me some SG5 lamps despite double checking they were the correct ones. :mad:

Personally I'd be happy with the halogen route if it works although obviously I'd prefer to keep the HIDs. The real problem is knowing exactly where the problem lies. Will the rear level sensor (and possibly front) solve the issue or is it something else too? What if the lamp motors are knackered too? What if... you get the idea! This is why I'm considering the halogens as it seems a route less fraught with problems.

I'll feedback, and thanks again. Much appreciated.

Thanks for the reply, again much appreciated.

The headlights are the biggest problem at the minute. The air pump is £100 to resolve locally and there's a handful of minor things expected of any fifteen year old car. I've had the timing belt done as it was needed and completely overhauled the rear brakes otherwise it owes me little. TBH I'd rather tackle some rust than this. I cannot believe how much of a challenge it is.

The idea of the spacers is what I considered if needed although how I could apply them I do not know; on the clear headlight it doesn't move an iota and I know from my previous car (a fabulously good fun Swift Sport) that they settle upwards by quite a bit when first turned on. Also it was my friendly corner garage that did my MOT although the tester is someone I hadn't seen before. They help me with my '99 Cougar so are known to be, ahem, 'sympathetic' when needed. :ROFLMAO:

My missus is keen for me to spares and repairs it as she wants to go down to one car instead of two* as we don't have the need anymore. The Forester has done its job over the summer with the house move and renovation and she now works from home permanently. It just annoys me headlights of all things could sink it. Crazy.

*we have another car. I don't count the Cougar as that's my summer plaything / restoration / tinkering toy

Oh forgot to add that there's definitely a small 'ball joint' kind of link at the rear, behind the wheels. I posted about it here at the time.
Just a quick update.

Luckily I was able to source a reasonably priced n/s headlight unit so I swapped that at the weekend. I still have to sort the alignment out. Other than the white manual adjuster on the back I can't see any other way to do it?

Picture shows the improvement it has made and just how bad the existing unit was, with the clouding on the inside that would not polish out. As it also continued to fill with condensation despite resealing it, a replacement really was the only way.


Thanks for those who took the time out to reply.
