I have a slight haze in my IS300 headlamps. It's not the outside. It seems coming from inside.
Is there anything I can do?

I got word that when I change my parking lights, I need to air it out?

Is that true?

 

I would first try cleaning the outside with the headlight restoration compound (lot of auto stores sell it)
if they are still hazy, then you could try cleaning the inside. Do a search, I think Tiguy99 had the thread if I'm not mistaken. Never did it myself but I think it involved placing the headlight assy. into an oven set at a low temp and heating it until the seal around the headlight lense becomes soft. You can then pull it off and clean the inside, then re-attach it using silicone...... great results from the pix!

good luck!
