Hello, my 2019 same color as yours has the same problem left side unit turn it on and seconds later goes out, appears to fall under a maintenance item and not covered as I had stopped by my dealer.
Looking for an alternative for it but still deciding. Regards
The following is from the warranty "exclusions" section of the 2019 Road Glide Owner's Manual. The emphases added are mine.
1. Parts and labor for normal maintenance as recommended in the owner's manual, or the replacement of parts due to
normal wear and tear including, but not limited to, the following:
light bulbs, tires, lubrication, oil and filter change, fuel system cleaning, battery maintenance, engine tune-up, spark plugs, brake, clutch, chain/belt adjustment and chain replacement.
Reading that I would have a discussion with your dealer. There is a difference between a "normal wear and tear" leading to burned out light bulb and a failed LED module; especially when the MTBF on those modules should be many year. Even more so when it's a multi-segment module with only one failed segment. Make a phone call to Mother Harley itself if the dealership won't entertain the discussion. Accepting this only because the dealer says so is letting them off way to easy.
