I like having my light on at all times, just from the safety aspect. The thing I don't like is how most car manutfacturers are now doing "daytime running lights" We used to stand out in the daytime, and now we're lost again....
P.S. with some creative wiring, you should be able to link the pass light to the lighting harness by way of a "loop" that would, or should allow you to flash them via the pass trigger.
Or maybe not. I am not an electrical pro, but it sounds feasible
