Transport Canada should enact a regulation forcing car makers to allow for maximum illumination of all dashboard instruments and read-outs when the headlights are on.
In most cars, switching on the lights means automatic dimming of the dash lights, on the theory that because you turn your lights on at night, you don't need the dash lights to be all that bright.
Not bad, given the theory. However, that theory is grievously flawed.
Because those of us/you who really care about traffic safety switch our real headlights on all the time, day or night.
Why? Because (a) we know 'lights on' makes us more visible and hence less likely to get into a collision, and (b) we know we cannot rely on Daytime Running Lights, most of which only switch on the front lights. Especially on freeways during inclement weather, having the rear lights on is much more important than having the fronts on.
(Some jurisdictions make it mandatory to switch on your headlights when the wipers are on. Not a problem for us - our lights are ALWAYS on.)
So to establish good habits, it's seat, mirrors and steering wheel adjusted, belt buckled, ignition on, lights switched on, every time, before we pull away.
But in cars without a max dash light setting, this leaves us unable to see the gauges and read-outs during the day.
Some notable exceptions that spring to mind: the Chrysler 300 family of cars, and various Nissan models. These typically have a rotating knob with a rheostat to vary the night-time dash light intensity to personal taste, along with two detents in the range of rotation. Click past the first one, and you get full IP lighting. Click past the second and you get the interior dome lights on.
All others, please copy.
