Flasher Relay

[RBRx]

Thanks I got my hands on one and wrestled the old one out, problem fixed.

I'll leave this bit of info here, I took my old relay apart and much to my surprise it "IS" an electronic flasher. Being dumbfounded why it would go faster with LEDs I looked up the datasheet on the chip and found this

"Lamp outage is indicated by frequency doubling during hazard warning as well as

direction mode"

So it would seem the flasher was designed to act like the ol' flashers of yesteryear when a lamp failed. Could probably trick the chip pulling up the "Lamp failure detection" PIN to trick it for LEDs but it depends if $12 dollars is precious to you to even go through the effort.
