[PWs1090r]

Hi guys thanks for the add. I've got aux running lights fitted on bar brackets that came with the bike. Unfortunately one has failed so I've bought so new lights but these are constructed as a main beam and angel light. From what I can tell without stripping everything the existing lights run off of the DRL so was planning on linking the angel lights directly to the existing. But my question is can I splice the main beam light so it runs the new aux light main beam so they illuminate when the lights are flashed or high beam is switched on.
Is this possible as a direct splice or do I need a harness to prevent flash ups from the ECU?
