Hello, I'm looking at the Hepco & Becker rear rack for my 2020 Speed Twin and understand the stock US turn signals won't fit with the rack. Will any of the Triumph OEM replacement turn signals work with both the rack and my bike's LED system? Or will I have to replace the entire rear brake light/flashers unit? Looking to avoid that scenario, which would mean a $260 rack turns into a $700+ upgrade.
