I just did the headlights on my 97 obs.
You need to pull the battery on that (pass) side.
With a deep 11mm socket remove the two nuts down low which are a bit recessed below the headlight capsules as I recall
Once the two nuts are removed the whole marker light and chrome bezel around the markers will pull out allowing access the turn signal bulb and both marker light.
Have a long magnet retrieval tool ready in case you drop one of the nuts into the darkness below the headlight.
OH,, also have some band aids ready for the for the back of your hand.....
