This is a very small problem but it is driving me nuts, or nutser in my case and I have a question born mainly out of confusion, frustration and my ignorance. First, I have a 2006 Heritage. A gasket/O-ring fell out of my right rear turn signal between the removable chrome ring and the lamp housing. It seems to be there to prevent water from entering the housing to prevent corrosion. According to HD it doesn't exist. I have an owners manual, it is not shown. I have a parts manual, it is not shown. My Local shop, which I trust explicitly and are a great bunch of people cannot find it anywhere in their books. I have searched the entire internet. It seems to not exist. My Heritage is obviously breeding new and original parts when left alone in the garage. I have actually taken pictures, see below, of this elusive non-existent existing O-ring in my left rear turn signal, and a picture of where it fell out of my right turn signal. You can only imagine how bored I am. Does anyone out there have any ideas what this little bugger is called and where I can get one, or several? It is an O-ring the diameter of the plastic lens and fits into the groove of the lens when installed. It is about the thickness of a human hair. Ok, I exaggerated there but you get the idea. Any assistance will be much appreciated. Anyone who finds out what this is deserves to be knighted personally by Glider, altho I am not sure I would trust him with a sword anywhere near my neck. Everyone have a good day and ride safe. Below: Behold my amazing photographic skills in an attempt to demonstrate my very deeply felt emotional loss of one said O-ring. The left O-ring in place. The right O-ring's previous home. The disgusting and rotting remains of missing O-ring.
