OK some info for you M8 Softail owners regarding LED headlights. I’ve just done a quick test (non scientific and no doubt not very accurate) to see how bright the stock headlight is on a Sport Glide in my case. I tested it at 13ft distance ( as that is all the room I have in my darkish garage) Low Beam was 49 Lux = 769.33 candela. High Beam was 174 Lux = 2731.9 candela.
More info to follow soon
