I got such great help on my last question so here is another one. As mentioned in the other post. We are new owners of a 2004 Mainship 40. I noticed a couple of the indicator lights on the DC panel are out. I unscrewed the panel to look and it appears these are not a simple bulb replacement. Looks like the indicator light is a separate unit and the bulb is not replaceable. If this is in fact the case, anyone have a source for replacements? Looks like they did not make this an easy fix. They appear to be accessible for replacement with a little effort and shutting the power off to the panel. Thanks, Joe
