The lights are required by DOT. This tells oncoming vehicles that they are meeting a wider than a car vehicle and on the rear also for the same reason. Do you think that RV manufacturers are going to put them on just for the fun of it? If they can save a penny anywhere they are going to do it.
Here is a link that shows what lights are required and if you look all the way at the bottom it shows a class "C" MH.
I would suggest that you should maybe make yours work again before some officer looking to hand out a ticket gets you unless you never drive at night than you don't need to worry about it.
The regs shows they are required on any vehicle wider than 2032mm which is 80".
I'm well aware of all of that.
A ruined front cabover section from leaking lights is well worth the chance I'm taking of having to maybe someday service a "fix it" ticket.
Beyond the letter of the law ... what purpose do these lights serve on a small RV used a few times a year that never gets near loading dock roofs and never gets near too-low gas station pump roofs? Well, I guess cabover running lights would make it safer at night for myself and low-flying helicopters.
I'm pretty convinced that cabover running lights leaking might be a major cause of rotted cabover wood in RVs.
Note that running lights on commercial trucks may leak, when they leak, mostly straight down and stay totally within the walls and drip out the bottom and not rot anything or not even be noticed for years. Commercial truck walls probably don't have much wood in them to ever rot, anyway, and who is going to notice or care about any mildew/mold smell in a truck trailer even if there were something inside the walls to mildew/mold.
