Since I am 12volt, I used a motorcycle flasher, which looks like one of those small square relays, and has a screw tab for mounting. It is electronic, so works well with LED lites. No 3rd leg for an indicator light though, but since I have separate indicator tell tale lights for each side, I did not need the 3rd leg. If needed, a couple tiny diodes would create a 3rd leg.
