Need to replace the headlamp on a 1998 Mariah Jubile. Looks like it's all one molded unit.

Headlamp? Are you meaning the docking light or the lite fixture in the head? Once you figure that out, look thru the Original Mariah Parts & Vendors List.

Assuming you mean the bow lights, I've been told they can be disassembled (possibly with a hammer) and a cheap $20-30 bulb from napa will then fit. I know it was done to one of mine. I can see if it's accessible enough to get you a picture. Iirc a hose clamp was all that needed for re-assembly.
