This sticker resembles New York's license plate design used between 1973 and 1985.
WLIR switched from Beautiful Music to a freeform Rock format in 1970. By the late 1970s they were mixing music from traditional album rock acts along with early "new wave" artists like Blondie, Television and the Talking Heads. In 1982 WLIR fully embraced this new era of music becoming one of the first Modern Rock stations in the country. They switched call letters to WDRE in 1987 but regained the WLIR calls in 1996 while shifting to an Adult Album Alternative format. In 2004 the station was sold and currently carries a Regional Mexican format as "La Que Buena 92.7" WQBU.
