I converted about 10 yrs ago, and used an automotive style low load flasher, as it was available and lower cost.
Today, electronic LED flashers can be bought for less than an automotive flasher.
One flasher I found (and txaero121 found the same model) is well under $10, small and rated at 0.02A to 10A. That easily fills the
range we need. At the high current side, our scooters run just under 50 watts (around 4 amps) with stock lamps. With a LED
conversion a couple amps less.
