I wouldn’t bother with the amber headlight on trails as there’s absolutely no need for it. I experienced that on the BWI trail one afternoon… I’m not sure why the guy had his light going full blast but he did. I’d also be hard pressed to turn it on strobe in the city as well… too annoying. A few weeks ago I went on a 42 mile ride through St. Mary’s County and spent about 15-20 miles riding the shoulder on MD-5. Good lighting is a plus in that situation.
