I have a light fixture in my rear trunk but it is burned out and seems to be a sealed unit. Anybody know where to get these?

i don't think they're sealed. (or are they?)
i believe the bulb is the same as the bulb in the interior light in your back-pad.

which also happens to be a common VW part (the bulb). you'll be able to get it at your local VW store ...

As far as I can tell it's the same bulb. Are you sure it's burned? It only comes on when the headlights are on. It's kinda a silly way to do things.

With just the head lights on? Well I guess they thought you would only need it at night while out on the road. I'll give it a try, thanks.

The trunk light is on the circuit that feeds the license plate lights. I think the lens should come off once it is unbolted, but it may be stuck from years of being attached.

Check from inside the engine side.

I have had it out. It looks like a little sealed unit. No screws or clips to remove a cover.
