    The Rinder manufactured amber lenses on all four indicator lights severely cracked during removal and reinstallation. The lenses must be rotated off the indicator base to change the light bulb. It is extremely difficult to remove the lens without an excessive amount of force. The rim of the lens that mates to the body of the indicator becomes so damaged during the removal and reinstallation process that the lens will not stay attached unless taped or glued. The lens should be designed to remove and reinstall easily and securely since bulb maintenance is a critical safety issue. This issue is noted by many Bonneville owners on various internet forums.
