A Yj Wrangler.
They made them from, like 1988(?) to 1997.
Every other Jeep before and after this (not including cherokees and other more road freindly jeeps) had round headlights.
Basically, square headlights are the quickest way to identify a Yj from a Cj or Tj, both of which were heaver built, and better for off roading.
The square headlights are looked down on by some people, because thats when they started softing them up, and loosing there kind of utilitarian "go anyware" feel.
Though I have no idea what Ranger Dave meant.
Not to say these are no good, but there certainly more road friendly than the CJ, and for $300, YOU SUCK!
when the square headlight model was introduced it wasn't long before die-hard Jeep enthusists were spotted with "real Jeeps have round eyes" t shirts and such. Chrysler switched them back to round eyes rather promptly.
