I attached a HOOOT (
https://www.amazon.com/HOOOT-Recharg.../dp/B07L7GQL44 ) red light to this mirror (
https://www.walmart.com/ip/Bell-Smar...irror/17619567 ) and transfer between bikes giving a left edge identification along with a center identification frame mounted red light under seat and my helmet mounted red light. Front is a HOOOT clear blinking with additional NightRider 650 lumen and 900 lumen for night riding.
Also have a 5,000 lumen 4 way attached to my night riding helmet and flashing blue Velcro strap light on left leg below knee.
