"no light on longer tours, even when going through tunnels I had to be careful to not run out of power."
In the 1960s I used to drive between Cambridge and Dundee which is 400 miles in a 1930 Austin Seven. The car had Lucas profocus headlights and were 35 watts.
In winter we would start at about 4:00am on headlights until it got light at about 8:00am. Drive through the day until it got dark then back on to headlights.
One journey took 17 hours and on that one the headlights did get noticeably dim by the end, but normally no problem.
However long are you tunnels?
