"Blinded by the Light" is a song written and recorded by Bruce Springsteen which first appeared on his 1973 debut album Greetings from Asbury Park, N.J.. A cover by British rock band Manfred Mann's Earth Band reached number one on the Billboard Hot 100 in the United States in February 1977 and was also a top ten hit in the United Kingdom, New Zealand and Canada.

The song came about when Columbia president Clive Davis, upon listening to an early version of Greetings from Asbury Park N.J., felt the album lacked a potential single. Springsteen wrote this and "Spirit in the Night" in response.

According to Springsteen, the song came about from going through a rhyming dictionary in search of appropriate words. The first line of the song, "Madman drummers, bummers, and Indians in the summers with a teenage diplomat" is autobiographical—"Madman drummers" is a reference to drummer Vini Lopez, known as "Mad Man" (later changed to "Mad Dog"); "Indians in the summer" refers to the name of Springsteen's old Little League team; "teenage diplomat" refers to himself. The remainder of the song tells of many unrelated events, with the refrain of "Blinded by the light, cut loose like a deuce, another runner in the night".

"Blinded by the Light" was the first song on, and first single from Greetings from Asbury Park, N.J. Springsteen's version was commercially unsuccessful and did not appear on the music charts.

Manfred Mann's Earth Band's recording of the song changes the lyrics. The most prominent change is in the chorus, where Springsteen's "cut loose like a deuce" is replaced with "revved up like a deuce." This is commonly misheard as "wrapped up like a douche" (the V sound in "revved" is almost unpronounced, and the S sound in "deuce" comes across as "SH" due to a significant lisp). Springsteen himself has joked about the controversy, claiming that it was not until Manfred Mann rewrote the song to be about a feminine hygiene product that it became popular.
