DK40 flasher unit

My caution/ts flasher has been intermittent and now has failed ON. This is important for me now as I have been snow plowing near or on my road. Anyway I just wanted to let others know that a standard 2-prong auto flasher works fine in place of the Dae Dong 3-prong unit and it doesn't cost $30.00. Use a standard one because a HD flasher blinks a little fast (but can be used).
I cut the old unit apart to see what failed and was surprised to see an electronic circuit board, wondering why they did this when a bi-metal (old school) flasher works without issue, seems like misplaced technology....am I missing something? perhaps the electronic flasher automatically compensates for additional lights eg a trailer plugged into the rear port....Mike.
BTW a 3-prong (old school) flasher blows the fuse.

Could be so the flasher will be compatible with LEDs on some of the tractors. Most of the old school ones won’t work with LED bulbs as they don’t draw enough to make the old ones operate.

Yeah, I put LED tails on my SUV and had to add resistors in the circuit to make them flash.
