I would change #3 to ALWAYS drive with headlights on..24/7, 365 days. Up here in the northeast sun never gets 45 degrees above the horizon in winter, sometimes the only way you notice an oncoming vehicle (in full sunlight mind you) is the pin-pricks of their two headlights. Many a near miss averted by NOTICING the other vehicle. Headlights are as much about being SEEN as they are about seeing. Worst, of course, are those in silver vehicles that drive in (daytime) fog with no lights on!
Many new vehicles have "always on" lights, and numerous countries (those safer than ours...hint, hint) require lights on when ignition is on.
And keep the lenses of lights, front and back, clean--at least a quick wipe.
