I see this is your first post. Let me be the first to welcome you to iRV2.
I see that you have a 2007 42QSP Allegro Bus. The 2007 Bus used the 3 rows of recessed quartz ceiling lights. Each row was controlled by a separate rocker switch in the hallway. I haven't heard of any problems with this design and mine works just fine. Either you have a bad wire someplace or a bad switch. This isn't typical and once your dealership finds the problem takes care of it properly you should have no more problems.
As to the water pump lights - some have issues and some don't. I went through 1 on my '04 Bus after 3 years but put two into my '07 so far. Again, it's warranty and they do go out every now and then. The new ones are LEDs now but if this keeps happening I'd have the dealership check your output voltage from the inverter/charger. If it's too high, you'll be blowing those LEDs frequently.
