You open the hood and locate the headlamp assembly, it should be a connector on the back that you quarter turn to remove from the housing and replace the bulb. Do not touch the glass on the new bulb, oils from hands can foul a new bulb.
Look at the back of the headlight housing. Depending on which side needs replacing, you may have to move the battery or the air box.
There may not be enough room to remove the headlight bulb without doing this. This job could be easy or complicated, depending on what you need to do to get to the bulb.
The bulb is usually held in place by a plastic ring that, once turned, is removed. You then give about a 1/4 turn to the headlight and you should be able to remove it.
Make sure that you do not touch the glass part of the new bulb with your bare skin. The oil from your skin will cause the light to blow once it's heated. You can wear gloves or just be careful to not touch the bulb when replacing it.
Once you connect the new bulb, put it back in the headlight hole and twist it until it locks. Don't forget to put the ring back on if you had one.
I usually try the headlight before I put it all back together to make sure everything is working.
You can check your owner's manual to see if there is a procedure to replace your bulb. There may be pictures to help you.
