How to set youtube theme parameter in JS?

Question

I've been working on embedding a youtube playlist with Javascript and I can't change the theme to light. All the other parameters work but this one doesn't come through.

This is how think it should work:

  var defoptions = {
        autoplay: false,
        user: null,
        playlist: null,
        carousel: createCarousel,
        player: createPlayer,
        thumbnail: createThumbnail,
        max_results: 25, // does not apply to playlists
        loaded: function () {},
        playopts: {
            autoplay: 0,
            egm: 1,
            autohide: 1,
            fs: 1,
            showinfo: 0,
            rel: 0,
            theme: light
        }
    };

Any thoughts?

Thanks!

Here you have the whole thing, it's far from finished but first I need to find out how to change the theme.

<style>

#container{
    background-color: #F1F1F1;
    padding: 20px;
}

.yt-descript{
    max-width: 100px;
    font-family: verdana;
    font-weight: bold;
    font-size: 9pt;
    margin: 2px;
}


.player {
    width: 100%;
    height: 305px;
    overflow: hidden;
    background-color: #F1F1F1 ;
    position: relative;
}



.youtube .carousel {
    width: 20%;
    height: 100%;
    overflow-y: auto;
    overflow-x: hidden;
    position: absolute;
    right: 0px;
    z-index: 3;
}
.youtube .thumbnail {
    margin-left: 2px;
    width: 90%;
    border: 1px solid black;
}
.youtube iframe.player {
    width: 80%;
    height: 100%;
    overflow: auto;
    border: 0;
}

</style>

<script>

(function () {
    function createPlayer(jqe, video, options) {
        var ifr = $('iframe', jqe);
        if (ifr.length === 0) {
            ifr = $('<iframe scrolling="no">');
            ifr.addClass('player');
        }
        var src = 'http://www.youtube.com/embed/' + video.id;
        if (options.playopts) {

            for (var k in options.playopts) {

            }
            src += '_a=b';

Theme needs to value string values, so try this:

var defoptions = {
    autoplay: false,
    user: null,
    playlist: null,
    carousel: createCarousel,
    player: createPlayer,
    thumbnail: createThumbnail,
    max_results: 25, // does not apply to playlists
    loaded: function () {},
    playopts: {
        autoplay: 0,
        egm: 1,
        autohide: 1,
        fs: 1,
        showinfo: 0,
        rel: 0,
        theme: "light",
        color: "white"
    }
};
