Defect
On certain motorcycles, the wiring harness for the left handlebar switch may not have been manufactured properly. As a result, the horn and/or the high beam headlight may not work.
Safety Risk
A headlight that doesn't work properly could cause reduced visibility. A horn that doesn't work could prevent a rider from warning others of an unsafe situation. Both issues could increase the risk of a crash.
Remedy
Honda will notify owners by mail and advise you to take your motorcycle to a dealership to replace the left handlebar switch housing.
