Irritaiting dot in sidebar

In my sidebar, right where the widgets are added (text) a very irritaiting bold dot is visible. I can’t understand where it is from?
Here is my sidebar-code:

#sidebar10 {float:right;width:215px;text-align:left;font-size:12px;background-color:#fff;margin:0 0 0 10px;padding:5px 5px 0 10;border-left:1px dotted;border-color:#ccc;}
#sidebar10 ul ul li a:hover{color:red;text-decoration:underline}
#sidebar10 ul ul li a:visited{color:#000;text-decoration:none;width:95%;padding:0}
#sidebar10 a:hover,#sidebar10 a:active{color:#fe0000}
#sidebar10 h2{font:bold 16px Geneva,Verdana,Arial,Sans-Serif;color:#000;text-align:left;letter-spacing:0;border:0;border-bottom:1px solid #d5d5d5;margin:0;padding:0 0 0 5px}

It is visible on this page; https://www.gevinstguide.com/2009/09/vegas-towers/
Note the bold dot beside each text-widget.
