adam1942 Posted December 27, 2012 Share Posted December 27, 2012 (edited) When I'm driving over some bumps I can see that my light is "shaking/Shiver" or if I'm going past signs I can see the light "shaking/Shivering" on the reflection.. Has anyone seen this before? I hope its not the light reflector within the light casing and just a loose bulb.. has anyone any ideas of what it could be or where I should look? It passed MOT but it only happens when driving and I don't want to be blinding anyone with the Bi-Xenons Edited December 27, 2012 by adam1942 Quote Link to comment Share on other sites More sharing options...
scubapics Posted December 27, 2012 Share Posted December 27, 2012 Is the headlamp assembly securely mounted? Quote Link to comment Share on other sites More sharing options...

adam1942 Posted December 27, 2012 Author Share Posted December 27, 2012 ^ Lol.. my mistake!! Scubapics - yes I cannot shake it with my hands from the engine bay area hence I didn't think it was the light cluster itself.. Quote Link to comment Share on other sites More sharing options...
Z-monster Posted December 27, 2012 Share Posted December 27, 2012 (edited) Could it just be the suspension rebound? As the light is projected some distance, when you see the wobble it's amplified by the distance the light travels. I also read in the handbook the headlights are self-levelling on the HR models, which might be another consideration Edited December 27, 2012 by Z-monster Quote Link to comment Share on other sites More sharing options...
Dicky Posted December 27, 2012 Share Posted December 27, 2012 I believe these headlights use a ballest to ignite the vapour within the lamp then keep it running in much the same way as a fluorescent light works. I'm thinking it might be a faulty ballest or loose connection to it. Do both lights flicker or just the one ? ( not sure if there's a ballest for each headlight or one for both) Quote Link to comment Share on other sites More sharing options...
adam1942 Posted January 2, 2013 Author Share Posted January 2, 2013 (edited) z-monster Its not the suspension rebound as its only happening on one light Dicky - There's a ballest for each light its screwed on with 3 screws to the back of each lamp and its only the left hand side.. What I've notice is if I hit the light with my hand the silver part inside is shaking however if I do this on the passenger side it does not! Is there a few screws or something that holds this part tight? Edited January 2, 2013 by adam1942 Quote Link to comment Share on other sites More sharing options...
cs2000 Posted January 2, 2013 Share Posted January 2, 2013 On most cars with headlamp adjusters the inside silver parts actually pivot, the electrical adjuster 'holds' the inside on either the top or the bottom and pushes or pulls it which aims the lights up or down so there wont actually be (to my knowledge) any screws or anything physically holding the inside in place. Perhaps it may wobble if the adjuster is adjusted 100% one way? dont know really. Quote Link to comment Share on other sites More sharing options...
adam1942 Posted January 2, 2013 Author Share Posted January 2, 2013 cheers CS I'll see if any of the adjusters are out of skew I wonder if I can just use a high temp glue from the back of the light to see if that would work? I don't fancy paying £1098+ vat from Nissan for a new one Quote Link to comment Share on other sites More sharing options...
Ebized Posted January 2, 2013 Share Posted January 2, 2013 I believe the perpex and reflector are a bonded unit - so if the reflector is moving on its own th bonding has come undone Best I could find to show the assembly and the fact it is ordered as one replacement part - items 3 & 4. http://nissan4u.com/...illustration_1/ Quote Link to comment Share on other sites More sharing options...
cs2000 Posted January 2, 2013 Share Posted January 2, 2013 heh, as i said, the way i described is the same with most cars, however some could theoretically have the reflector screwed/bonded in place and the adjuster just move the HID projector unit. Seems a rather fiddly way of doing things however. Quote Link to comment Share on other sites More sharing options...
