Define "aircraft landing lights"?
I recall they were popular here in the '70s, but they were around the 3½" (maybe 4" tops) diameter. Based on the 'bigger is better' axiom, I bought a pair of Super Oscars which were sensational. Gaining perspective from "If it looks ridiculous....", I sold them to a mate for rally use on his 240Z and bought a pair of Oscars...which I still have.
Cheers,
