    use of a / an

    We are working on an electrical course.
    One of the lines is "most power sources have a LED that....."
    Should the a before LED be an?

    in case you pronounce it as one word "led" you have to use "a" as indefinite article. however if you pronounce it as a contraction L E D here you have to use "an" not "a"
