I agree it's not great driving at night now. Vehicle lighting appears to have become a bit of a 'free for all' over the last few years, despite all the regulations. Some people just seem fit whatever they want. Too bright, too dim, wrong colour, etc. Sequential and alternating direction indicators! With modern technology like LED's, all lighting and signals should be much easier to see day or night. However, that doesn't seem to be the case with some modern vehicles :-?
I remember as a child in the late 60s seeing a Tomorrow's World, with I think James Burke, telling us about new technology that would give us indicators that flashed across in the direction the vehicle was going to move, but he caveated the report by saying they would be illegal under the then current lighting regulations.
Now, as you say, it's a ruddy free-for-all with designers being more concerned about a 'feature' than the practicalities and function of their lighting.
Factory fit rear lights can have indicators ranging in size from a 50p coin to the length of a 12" Ruler or more, with some cars having larger lights than HGVs; while front DRLs can be all manner of shapes and sizes, seemingly a contest to make the most bizarre shape possible.


I recently stumbled across Mazda instructions on line for how to disable the DRLs on a CX5, though why they would provide this facility is beyond me....
but it makes resetting the typical 'Service Due' indicator on a modern car seem like child's play... :roll: :roll:

We've noticed several times that the flash of a front indicator on a modern car might be visible from our passenger seat whilst being invisible from the driver's seat; and vice versa. This seems to be due to the design of LEDs giving only an almost continuous arc of illumination - moving one's head slightly to change the angle of viewing instantly makes the offending indicator change status. We don't need jokes about "is it on?" "Yes...no...yes...no...".

The 50p sized indicators seem to be hidden in the centre of circular brake lights, the latter completely overpowering the former; and the colour separation being so poor that they merge into one light.

There's one make of delivery van favoured by supermarkets that has rear light clusters where the indicator is shaped like an arrow head. That's good, except the left hand one points to the right and the right hand one points to the left.
I just don't understand how the designers can come up with such ridiculous ideas.

I quite like the long indicators where the segments illuminate progressively; but does it really add anything to the function? Just because one can do somethinkg, doesn't mean that one should do it :-?
