I upgraded the lighting on my '08 FunFinder 210-WBS and my Cougar 318SAB.
Your '08 FunFinder should have tail lights by Command Electronics, here is the link:
Command Electronic Tail Light LED Upgrade
Unfortunately, the Cougar used Barqman lights and they didn't have an "upgrade" kit for the tail lights. I wound up having to replace the entire tail light assembly. Easy enough to do, but, not as easy as the Command upgrade. LED change was a worthwhile investment; much brighter for safety and visual impact.
