Rangers are the same way (at least my older ranger is). I always keep a couple on hand…but they are a little pricey. It sucks having to buy the whole new housing, if the only thing that is wrong is the 78 cent bulb. Take the bad light housing and cut around it with a dremel or small hack saw, replace both the bulbs with new ones and epoxy back togther. Doesn’t have to be pretty, just needs to keep water out. Here’s a photo of Ranger’s enclosed lights…I assume Champs are somewhat similar.
PS-There’s a reason they’re all going to LED’s
