Greetings all. New here and thought I'd add to this. Mine was doing it on the L side as well. Must be a problem from the factory. But anywho; It's not the bulb. It's the female side of the plug. You may have to pull the fairing off to get to the plug; I was able to pull the wires through the top. I just put a slight bend in the male prongs (enough to make good contact) added a dab of electric grease and plugged back together. I haven't had any issued since I did it over a month ago. Hope this works for you too.
