Ummm...no. They weren't. Not unless you bought your '92 Explorer in
Germany, where glass-and-metal standard-format 200mm x 142mm rectangular
lamps were used (same size/shape as the large rectangular sealed beams in
your '81 Chev pickup, but in Europe they were a replaceable-bulb H4 unit).

North American-market Explorer headlamps used a plastic lens and a plastic
reflector.
