Added a couple of good quality Bargman LED single tail light 86 series to my Mountaineer. Very little effort as I just wired them up in parallel over the current tail lights (to keep the license plate bracket and light). They are very bright and if it keeps just one guy from tail ending us, it is worth it . Update: Found the tail lights originally on etrailer.com for about $35 each. I am unfamiliar with the specifics on the Montana tail light, but if it is 4" dia., then they may have something that may replace the original for even less than what I paid!
