The Original AHC Titmouse taillight is the most beloved and copied taillight of the 21^st century. I feel this is the most beautiful taillight of its kind and will endure the winds of changing trends to come. From a completely stripped chopper to your late model bike, there’s a style that will fit your vision. All my taillights are dual intensity and need only a ½” hole to be mounted. These are 1-5/8” OD and length.
