glasgow Posted June 21, 2013 Share Posted June 21, 2013 Nearside headlight points toward flyovers on motorways - wonder how this passed 3 MOTs.... I had a read in the archive but not sure how to loosen the fixings I can only see a "big" nut under the case, is this the one that i need to loosen? It doesn't want to loosen ☹️ Thank you Ahmed Link to comment Share on other sites More sharing options...
revilla Posted June 21, 2013 Share Posted June 21, 2013 Yes that's the one, you will need to get a big spanner round at it an angle. If it's really stuck you may need a bit of WD40 or Plus Gas. However it is sometimes possible to move the headlight without loosening the nut, but not very easy to align accurately like that. Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted June 22, 2013 Share Posted June 22, 2013 22mm spanner. Or a big adjustable. Careful with the single wire that wants to get trapped between the spanner and the flats of the nut. Are you turning it the right way to loosen it ?

RS2000 Posted June 22, 2013 Share Posted June 22, 2013 It is a pain... I adapted a ring spanner to make it easier as shown here: Link to comment Share on other sites More sharing options...

andy_h Posted June 22, 2013 Share Posted June 22, 2013 A large adjustable spanner works fine. I never tighten mine up very right as they always get moved and I can then move back by hand. Link to comment Share on other sites More sharing options...
RS2000 Posted June 22, 2013 Share Posted June 22, 2013 Used an angle grinder to cut the slot..... Link to comment Share on other sites More sharing options...

Roger Ford Posted June 22, 2013 Share Posted June 22, 2013 Quoting Stationary M25 Traveller: 22mm spanner. Or a big adjustable. Not 22mm but 21mm (or some Imperial equivalent). The more common 22mm will work, sort of, but it's not a good fit. Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted June 22, 2013 Share Posted June 22, 2013 I have 22mm for my garage door spring tensioner. Work fine on my headlights. Link to comment Share on other sites More sharing options...
Mark Durrant Posted June 22, 2013 Share Posted June 22, 2013 Roger is correct 21mm is the correct size just in case someone decides to purchase a spanner Link to comment Share on other sites More sharing options...
Ozzy Posted June 22, 2013 Share Posted June 22, 2013 You can actually buy a spanner like that, usually known as a "crows foot", but if not, angle grinder works fine. Also, if I was you, take the headlamp bowel out, before you attempt to undo it, and also when re-tightening. There is a locking tab inside, which sits in a slot, which is supposed to stop the threaded shank turning, when you undo/tighten the nut. Invariably, as these are cheap rubbish, probably made in China, the tab will pop out, and you will find that you've been turning the cables round & round! Oz.

Member Jonathan Kay Posted June 25, 2013 Member Share Posted June 25, 2013 21mm crow foot wrench for £10.75 (I use an adjustable wrench) Jonathan Link to comment Share on other sites More sharing options...
Roger Ford Posted June 26, 2013 Share Posted June 26, 2013 Quality 21mm spanner is £7.99 from Halfords. They even had them in stock at my local "Metro" place. With the right size spanner, it's easy, you don't need anything special. 22mm spanners slip (not surprisingly), and adjustables tend to foul on the indicator pod.

TomB Posted June 26, 2013 Share Posted June 26, 2013 Make sure your not lazy like I was once and remove the nose first. I have a scuff on the nose where the spanner once slipped! Link to comment Share on other sites More sharing options...
MereCat Posted June 26, 2013 Share Posted June 26, 2013 To add to this ....any suggestions on getting them aligned correctly? I get a great view of the immediate tarmac at the moment even though we thought they looked correct visually...minor adjustments are required...

Stationary M25 Traveller Posted June 26, 2013 Share Posted June 26, 2013 Level ground, wall or garage door. Measure height above ground and centre to centre distance of headlights. Park car something like 20 feet from the wall and mark headlamp height and spacing on the wall with chalk or masking tape. On main beam, light beam should be centred on the marks ... ie parallel to the ground. When dipped, the straight cut off at the top of the beam should be just below the marked centre point.
