Hey Scotty, I purchased a 2007 Kia Optima and the headlights only work on bright. When on bright, they shine at low brightness so I'm able to drive at night. No light shines at all when trying to use the dim setting. All of the research I have done claims the only solution is replacing them with aftermarket headlight assemblies which is quite costly. Can you provide and advise regarding this? Thank you in advance!
