WHEN RIDING IN THE RAIN ON MY 2010 HARLEY-DAVIDSON FAT BOB, MY TAIL LIGHT HAS FILLED WITH WATER, AND THE BULB FAILED (STOP AND TAIL). WATER GETS INTO THIS AREA BETWEEN THE REAR FENDER AND THE LICENSE PLATE/TAIL LIGHT BRACKET FROM THE INSIDE. THERE IS QUITE A LARGE AREA HERE TO FILL WITH WATER, WHICH GOES UNNOTICED. THE DAMPNESS BEHIND THE TAIL LIGHT HAS CAUSED MAJOR CORROSION IN THE WIRING AND MAKES THE TURN SIGNALS COME ON BY THEMSELVES DUE TO SHORTING OUT A PRINTED CIRCUIT BOARD, INTO WHICH THE TAIL LIGHT AND OTHER COMPONENTS PLUG INTO. THIS EXACT SAME PROBLEM ALSO OCCURRED ON MY 2008 MODEL (OF THE SAME MODEL MOTORCYCLE), AND I AM AWARE OF SIMILAR ISSUES ON THE 2011 CROSS BONES MODEL (WHICH SHARES A SIMILAR REAR FENDER/TAIL LAMP DESIGN). THESE MOTORCYCLES ARE MANUFACTURED AND SOLD BOTH IN THE USA AND THE 'INTERNATIONAL' MARKET, WHOSE VERSIONS HAVE IDENTICAL COMPONENTS IN THIS AREA. I BOUGHT A 2010 MODEL (NEW) DUE TO MULTIPLE REPETITIVE FAILURES OF THE PRINTED CIRCUIT BOARD DESCRIBED ABOVE ON THE 2008 MODEL CAUSED BY THE SAME ISSUES OF WATER INGRESS, AND WITHIN WEEKS THE SAME PROBLEM HAD APPEARED ON THE 2010 VEHICLE. BOTH MOTORCYCLES HAD BEEN TAKEN IN TO AN OFFICIAL DEALER WHO REPLACED THE CIRCUIT BOARDS (ON MULTIPLE OCCASIONS ON THE 2008 VEHICLE) BUT THIS DOES NOT STOP THE WATER GETTING INTO THE AREA BEHIND THE TAIL LIGHT IN THE FIRST PLACE. *TR
