I bought this IS250 2007 a few days ago. So far things run well but I notice there is 'AFS off' on the dash and I think one head light is on with another high-beam. If I turn the high-beam all 4 bulbs turn on so I guess it probably wired wrong by the previous owner. Plan to take out the bulbs later but I wonder if anyone have this problem before and can give me some advice? Thank you.
