Drivers side headlight bulb aint working anymore. Suspect the constant fogging and nice trap of water inside the cover may have something to do with it.

Am I correct in saying that to change a bulb requires a lot of reseal work?

If so, is it possible to get this type of work done at any bodyshop rather than a 200 mile round-trip and a day off work.

Cheers in advance.

Surely the bulb replacement procedure is in the manual? It is for the GTO3.

yes it is and from memory involves breaking seals unless I was drunk when I last read it.

Yes, all bulbs on the Noble require the seal to be broken (and then resealed) - I do wish they'd re-engineer this - surely it can't be difficult to have fitted standard, rear-entry units?! Consider that, due to this "fixed" design a mere blown bulb occurence of a becomes a full breakdown!

Also, remember that the front units will need realigning so check that your people can do this correctly first - otherwise its a main dealer!

I've used this trick for years, and seen many garages do it.

Park the car opposite a wall where you can do the work.

Put the lights on full beam and you should notice a "cross" around the middle of the beam. Get a bit of chalk and mark up that point.

Take the unit out and change the bulb.

Put the unit back in, put main beam back on, and get the cross back to the same point.

et. Voila!

Interesting point but considering the bulb is already blown I'm not sure this method will work !

Has both dipped and main beam gone? Usually in my expierence the main beam keeps running, hence the suggestion.

If not, then just use this more accurate way

Full specification here
www.motuk.co.uk/manual_160.htm

or, the more rough and ready way from the AA car maintenance book:

1) Get car up close to a wall at a right angle, bounce car to settle suspension
2) Chalk a vertical line at the centre of each headlight (should now have three lines)
3) Chalk a horizontal line that goes across all three vertical lines at the centre of the headlights
4) Reverse car back (perfectly straight!) 25ft, bounce car to settle suspension again
5) Switch main beam on
6) Cover left light, use the adjusters so that the bright spot is 2 inches below the intersection of horizontal and left vertical lines
7) Repeat 6 for right headlamp (with right chalk line!)

To be honest you could just bodge it in. All you need is the bulb and some silicon sealent. You can just wiggle the bulb to get a best guess estimate (turn the lights on though obviously). Thats all most garages would do.

p.s. if its any consolation, I'm geographically close to 2 service centres. The reality is that its still about 1.5 hours each way thanks to our efficient road network

dealer called me and told me its ok to change bulb without worrying about checking levels. Apparently I won't disturb them by changing the bulb.

A trip to B&Q tomorrow for some Silicon Bathroom sealant !

I'd go out and chalk-up both headlight aims against the garage door now so that if either of them do blow then I'd be ready for it !

well all I can say is - that was fun !

Removing the old sealant takes some time, what a total pain in the you know what. Original bulb had actually popped inside lense so I'm not sure how I will ever be able to get the glass out of it.

Anyway new bulb in and fitment resealed. Phew !
