html – Is it possible to create a glow effect in SVG

I’m learning SVG and I would like to know if it is possible to create this kind of glow effect with SVG, interactively as in the following example -hovering trigger the effect – https://codepen.io/FelixRilling/pen/qzfoc

The fact is that I’m wondering how to make the light come and go, the advantage of SVG would be a more accurate effect with better shape following, this kind of advantage. Is it possible to do that with SVG?

Following, the code with HTML CSS

HTML:

<div id="container">

    <p><a href="https://en.wikipedia.org/wiki/Red">
        RED
    </a></p>

    <p><a href="https://en.wikipedia.org/wiki/Blue">
        BLUE
    </a></p>

    <p><a href="https://en.wikipedia.org/wiki/Yellow">
        Yellow
    </a></p>

    <p><a href="https://en.wikipedia.org/wiki/Green">
        GREEN
    </a></p>

    <p><a href="https://en.wikipedia.org/wiki/Orange_(colour)">
        ORANGE
    </a></p>

    <p><a href="https://en.wikipedia.org/wiki/Violet_(color)">
        VIOLET
    </a></p>

</div>

<div id="linkBack" style="position:absolute;right:0px;top:0px;background-color:#333;margin:0;width:60px;padding:5px"><a href="http://www.f-rilling.com/projects/" target="_blank" style="font-size:14px;text-decoration:none;color:#fff;padding:0 0 0 5px;font-family:sans-serif">My Site</a></div>
