My 73 350f was rewired by the previous owner into a cafe style 2 light under the seat brake lights. I love them although I have been told by the cops there illegal most don't seem to care. Anyways I replaced both bulbs this year, and I just noticed that one isnt working correctly. When I turn the bike on both brake lights are on, however as soon as I use either the front or rear brake the light dies. Any ideas? Thanks
