I noticed yesterday the low beams didn't work on my 2010 Roadster. Upon investigation today I discovered that apparently one of the Eastern Beaver relays I installed 20K miles ago has quit working. Swapping relays between high and low beam circuit has whatever circuit with the original high beam relay working. Since I rarely ride the Roadie at night I've jumpered the high beam circuit and left the good relay in the low beam circuit until I can source a replacement.
This is one of the early kits installed 12/27/10.
Just a heads up - when I pulled the relays there was visible corrosion in spite of copious amounts of dielectric grease, so you might want to check yours if they have some time on them.
