Seems like it would make sense to mandate a specific height for headlamps. I wonder why this hasn’t been done.

Edit: sorry, I shouldn't post US rules on a UK topic. For penance, a fact about lighting in the UK, reverse lights weren't required until 2009!

There are rules. FMVSS [1] says lower beam headlamps must be mounted between 55.9 cm and 137.2 cm above the ground, and upper beam headlamps must be mounted not less than 22 inches nor more than 54 inches. The height ranges match, but are specified in different units

But that's a big range.

These rules end up being the stick used to regulate vehicle lifts and lowering; you could lift a vehicle higher, or drop it lower but very few people will do the work to relocate the lights.

this is also my understanding. The range is large because it caters to passenger cars, lorries and construction equipment. Construction equipment is seen are more rugged (it often is) and this is now projected as a desirable trait for SUVs and pickup trucks.

The irony is that SUVs and pickup trucks do not need lights 137 cm above ground, but that height is perfectly legal in too many countries. These vehicles are a menace and should be legislated out of existence.

I will always champion the compact pickup truck. A 1980s S-10 or Toyota Truck (HiLux) can do light truck things, is relatively economical, and doesn't have a large footprint. Alas, nobody makes similar vehicles for US/Europe anymore --- kei trucks are still made for Japan, and less developed economies can get simple small trucks. Maybe some of the EV compact trucks will actually be made.

		I'd argue that compact trucks should be the only trucks that can be driven without special licensing. It's insane to me that I as a 16 year old was allowed to drive an F350 pulling a 40ft trailer on a standard license.
