    We all know that changing from traditional filament turn signal bulbs to LED's confuses the standard HD flasher unit. Has anyone changed the thermal flasher to an electronic flasher rather than using resistors to adjust the current for the LED's? Is there a standard auto thermal flasher on a HD?

    Will this confuse the cruise control? I read something about that being tied into the brake lights/turn signals and might cause a problem.

    Any thoughts appreciated.

    It's a bit more complex than they way you are looking at the flasher.(thermal flasher)

    Harley uses a TSSM/TSM (turn signal/security module) which incorporates a few other functions and is wired into the main harness of the bike. Replacing lights with LED's lowers the operating load on the TSSM/TSM and that's why the load equalizers are required rather than trying to sidestep the TSSM. The load equalizer adds the additional load that the stock bulbs imposed on the TSSM when you switch to LED's which impose a lighter load on the TSSM and usually makes the directionals inop.

    Gilder,

    I thought the problem was the flasher by itself, and now understand why the fix isn't so simple. This also explains why no one just switches flashers.

    Thank you for the reply.
