Unfortunatly, not every RV mfgt uses automotive light assembly's. Our Damon has a headlight assembly that was designed/ordered by Damon and was used on 2 or 3 models...it's a Damon original.
Our Outlaw group has made contact with the manufacturer and confirmed that is the case for our rig's.
I took a quick look on Google images at pictures of other "2002 Fleetwood Pace Arrow's" and it looks like you may have the same problem, 'cuz they don't look familiar to me.
I'd call the mfgt's customer service line and ask - if you can.
Best of luck
