What is the condition of reflector? "Buffing" aint going to fix it. The reflector needs to be in good condition and not oxidized/burnt (usually happens after osumm 90/100 watt bulbs) and then the reflector needs to be calibrated. Put in proper 55/65 watt H4 bulbs. Never install HIDs in halogen lens (unless its a proper retrofit with projectors), you will cause accidents by blinding others.
