Is it possible to replace the bulb of the reversing lights, an if yes, what type of bulb I should buy? My 2013 MS85 with Tech Pkg has the left reversing light burnt (or at least not operational) with some moisture inside the housing. (I'm in Canada so I expect to have two reversing lights turning on when I back up, not just one like the English ;-). I've been googling for a while and found videos about how to replace the complete housing, blow air in it to dry it, etc., but could not find if I can replace only the bulb, and if I do, what kind of bulb it is. Or do I have to replace the compete housing? Thanks in advance for the tips.
