made a little hood from a yogurt container. even used some aluminum foil since it won't give me Alzheimers ;-) I think it helps, but a longer one would do more
this is high power. it has 2 lower settings I can try
manually covering the light on the trail w one hand for ea person won't work for me. too many ppl. not saying I won't or don't do it, just can't do it for everyone. I'd rather find an angle, brightness setting & hood accessory that I can keep for the populated sections. further west on this trail, this time of year, is pretty empty except for other riders w strong lights & we don't bother each other. car drivers deal w oncoming headlights all the time. it is what it is. aim your lights & don't look into oncoming lights. unfortunately tho there's no standard or regulation for angle, brightness & focus or beam pattern, for bike lights like there is for car lights, so we're all doing our own thing
this is without the wide angle & hood
