Pat Brown from Bridgestone/Firestone says there are two types of headlights. One is the sealed beam (figure A) -- the bulb is an integral part of the lenses (they are al one piece). If you have this type, you need to inspect it before replacing the entire headlight because you may have a lose connection, etc.
The second type is what most cars have today and you only replace the bulb, not the entire headlight. Most headlights have a locking ring or turning mechanism. Turn this to remove the bulb mechanism. Carefully remove the bulb without touching the halogen bulb. When you touch the halogen bulb, you get oils oil and grease from your fingers on the bulb and you can ruin the bulb.
When you remove the bulb, look at the bulk and the contacts of the bulb (figure B) to see if there is any corrosion.. If they look fine, the odds are the bulb has burned out.
You have a choice when replacing the halogen bulbs as to how bright you want the bulb. If you accidentally touch the bulb, put some rubbing alcohol on a cloth and wipe the bulb off, Reconnect the bulb and insert it back into the headlight. Make sure the connection is snug.
