I was a bit dismayed by the recent failure of my Morgan-supplied Turn Signal Module, and I suppose I have to resign myself to whatever quality- control (or lack thereof) is being implemented by the factory.
I will be installing the Watt TSM, and hoping for a better result.

Hi Tom, the Alister Watts TSM came via me. He has a minimum economic batch size for production so I have been ordering batches and passing these on at cost.

The MMC module has a fundamental weakness to over or reverse voltage whereas Alister's has robust built in protection for these. It also has additional functionality in allowing user selection of the time before automatic cancelling (nominally 7 seconds, 14 seconds or off) and also functions as a peak battery voltage recorder which can help check the health of your battery.
