According to federal standards
, "front clearance lamps
" (amber forward-facing lights on each side) are required on any trailer 2032 mm (80") or wider
. In the Escape lineup, this means everything larger than the 17' or original 5.0... so the original did not require them, and the 5.0 TA does (as do the 19' and 21').
The requirement is not related to the height
, but they are to be placed "as high as practicable", as these are.
The requirement for rear clearance lamps
on wide trailers is similar, and so the 19', 21', and now 5.0 TA have them, suitably placed up high.
Front side marker lamps
are required on all trailers, regardless of width, height, or length. I don't know why the one I see on the driver's side is at the front of the lower body, and not "as far forward as practicable" up on the nose (like the classic 5.0), since the forward-facing lights would presumably not meet the requirement for side-facing markers. Maybe not all the lights were installed at the time of the photo. A gooseneck trailer would place the lights back there on the full-width body, but the 5.0 continues essentially full-width to the front.
