Answer:
Hi,
If you are referring to the front side marker light, it is relatively easy to change.
The first thing you have to do is open the hood and then remove one "wing nut" type bolt that holds the turn signal assembly in place. Then you can pull the assembly straight out with a firm pull.
Once the assembly is out, the bulb holder just turns about 1/4 turn and will come out. Remove the bad bulb and replace it with a new one. I usually like to test that the replacement bulb works before I put everything back together, but putting the assembly back in is the reverse of removal. Just make sure that you put the back end "tabs" in first, and then push firmly to seat the assembly. Put the wing nut bolt back in and tighten it.
That should do it. I have put a link to a page that has pictures of that area, including the wing nut bolts.
Good Luck, Greg
