No and yes.  The E-code lights give full illumination out to distance
X and then stop; with a rising slope to the roadside side of the beam
to help with signs and such.  DOT lights gradually fade away starting
at X minus a good bit and ending who knows.

Must be halogens -- the lamp envelope is small and the overall units
are sealed in the sense that you can't disassemble them.  But unlike
"proper" sealed beams, they don't burn out in a few minutes if they
get a little air or water inside.
