On another note some LEDs are stupidly easy to replace on rides, and some actually require a special tool in order to replace. It's not really about difficulty of replacement that makes upkeep so difficult, it's actually price. It seems to me Verbolten's 'eyes' problem stems from a lack of budget in order to replace the bulbs, combine that with the facts that LEDs ARE NOT CHEAP and the fact that the majority of any park's maintenace budget is focused on just keeping the rides running and you end up with this kind of situation.
Let's not forget that this could also fall in a dispute between BGW's maintenance and rides departments. Considering rides will be adding a new coaster and maintenance will be budgeting for that new coaster and you have a whole new monster to play with for next year, too. Which leads me to believe the issue will stand for quite some time until it gets addressed.
