Harleytoprock, is there any chance this was the original desgn of your unit? Maybe it was something to help catch the attention of other drivers. Or, did this just start acting differently than it used to?

Del, my EF-32 electronic flasher only uses a relay, resistor and capacitor, so it isn't bothered by RFI, like some more sensitive transistor units might be.
