well i have a 2004.5 GLI and one of my headlights seemed to be noticeably dimmer than the other so i went ahead and ordered new bulbs thinking it was going out. i then install the new headlights and the driver's side headlight is noticeably dimmer just like before. it could be in my head but it seems as if the rear running light is also dimmer on the same side. does anyone know what could be causing this ?
i have already checked fuses and i've already pulled my battery and checked the grounds underneath.
