    Who can tell me what I can replace my burnt out turn signal relay with?I have rear running lights .Wehrle BMW #1 244 392.2 the relay is the original and finally died after 500,000km or so.I'm hoping there is a TRIDON or Bosche aftermarket, the Stealership wants almost $50.00!!! Thanks Gronk

    TRIDON EP35 thanks to airheads .org for a VW/AUDI oem part number which gave me TRIDON EP35. It works perfect,$11.00 plus tax sweet. Electronic and it will handle LED.:deal

    Are these for GS or G/S ? My 92 GS with the switches on each bar and a seperate cancel switch has to have the BMW indicator module as far as I know

    Works in R100 GS 1987-1990 I believe ,turn signal switch on left control only.There are options for newer bikes but I don't have 4 way flashers so a 3 pin relay works. TRIDON does have a relay for your bike and it works in K bikes also.:freaky

    The "K" style flasher is used from 91 on. If you have K-style switches, you have a K-style relay.

    Since I've never owned a "K" bike, what exactly are K switches? Is this the style where the turn signals are actuated from both the left and right sides like my 93? I never knew this was called by that name before.

    Try Kisan Mfg. They have several kinds of turn signal relays. Needed one for the LED conversion on my 81 R80 GS. Programmable if need be.

    Thanks for the thread... helped me.

    My search for the same answer also came up with the reference pdf at

    http://www.tridon.com.au/downloads/downloadfile.aspx?D=45149

    ...which has turnsignal pinouts and schematics for a variety of different flashers... for example, the ep34 looks identical, but the voltage pin polarity is reversed from the ep35. (see page 9 and 10)

    Hope that this information is helpful,
