rubberman Posted March 13, 2009 Share Posted March 13, 2009 I searched around & saw many posts concerning the headlight bulbs burning out and various theories. None of those threads showed any pictures of the actual burnt out bulbs, so I thought that I would show some pictures of my dilemma. I got the car used with 36k miles about a year ago, had Sylvania bulbs on both sides. The passenger side burnt out (and deformed/melted the bulb glass some), so I replaced it with a cheap Philips 55W bulb from Advanced Auto so that I could mailorder some better bulbs. The Philips bulbs were working fine so I left them in for several months until the pass. side burnt out. I then put in Osram OffRoad 65W bulbs and ran them for about 9 months or so before the passenger side bulb also burnt out. Take a look at the bulbs, the Philips bulb is still clear, but it has an obvious shiny/silver discolored area on the interior of the bulb. The other blackish bulb is the Osram, and the actual glass bulb housing is bulged / deformed and interior is blacked out. I checked the other driver's side Osram bulb, it looks fine and no discoloration or deformation. I pulled the bulbs and felt just inside the projector to be sure that nothing was making contact with the bulbs causing a localized heat buildup; nothing is in the way & bulbs were mounted properly. I think that I have a wiring issue on the pass. side that was present even with the orig. bulbs because of the deforming glass bulb surface (happened with them also). That seems to be the only way that it could overheat that much and deform the glass (as in too much current from high wiring resistance) ??? Either way I need to swap bulbs and maybe consider adding a low beam headlight harness w/ relay hooked to the battery to get around any potential wiring issues. Thoughts / suggestions? Pics attached: blackish bulb is the Osram, clear bulb with dark spot is the Philips Link to comment Share on other sites More sharing options...
