I am seriously considering purchasing this shift light: http://www.caraddiction.co.uk/sld5.htm But I am concerned about a warning in the instructions: WARNING – The SLD5 shift light system is not suitable for capacitor discharge ignition systems where the green input wire would normally be connected to a coil negative terminal. However, if the capacitor discharge ignition system has a low voltage rev counter signal output, it will work perfectly. I assume the V-Max does not have "capacitive discharge" ignition? I know about the "Shift-i" from https://ecliptech.com.au/shift-i/. But it's more expensive, and I'm concerned about rain water seeping in through the buttons on the face.
