I really feel that there is insufficient overlap between high and low beams. So that when high beam is selected, the road immediately in front of you disappears. Ideally, I would like to arrange for all four lights to be "on" when high beam is engaged - like it it is when you hit the "high beam passing switch".
These standard globes are only rated at 55w each, making 220w @ a nominal 12V = 18.33Amps, with all four illuminated. Surely this low-ish current wouldn't adversely affect the charging system. Others more in the know might have some input into this theory.
