Jazty, yes I did for mine.
I talked to a lot insurance people before i actually ended up approaching my own company i am currently with for my truck and house.
Basically this is what i was told and learned in the process.
1) It's way easier to insure if you have multiple things with that company.
2) Don't use the word "School"!! I went in and had my ownership converted to recreational vehicle / passenger vehicle instead of commercial and told them it was an "RV" which is what it was registered as. When she asked me the body style i said it was a "bus" body...
3) Using a broker that deals with classic cars or specialized insurance is the way to go if you have no luck with your own company.
Hope that helps!
So i have spent the last few days and converted all the lights on the outside to LED. I was lucky to find the exact size round lights on sale at Princess Auto. It's by far been the easiest install on bus so far.
Here is the old beside the new:
All of the main ones done.. Still have to do reverse lights and lower tails / turns... I am not sure why you need the lower ones as it just duplicates the uppers. Maybe incase the uppers fail...
