Lost my bullets

I messed around with customizing my Child Theme a bit and somehow I managed to lose the bullets for my unordered lists… ordered lists are just fine.

Potentially relevant Custom CSS:

body{ background:#f7f7f7; margin:0; padding:0; font-family:Arial, Helvetica, sans-serif; font-size:14px; color:#999;}
.center{ margin:0 auto; width:85%;}
a{ text-decoration:none;}
p, .widget_wrap{line-height: 26px; text-align: left;}
li {
display: list-item;
text-align:left;
}

_____________________________________

/*SINGLE*/

.thn_post_wrap img{ max-width:100%; height:auto;}

.meta_comm, .catag_list{ display:inline;}
.single_metainfo{ padding-bottom:20px;}
.single_metainfo .vcard{ float:none;}
.single_metainfo, .single_post .single_metainfo a{ color:#999; font-size:13px; opacity:0.8;}
.single_metainfo i{ opacity:0.6; padding-left:10px; padding-right:5px;}
.single_metainfo .fa-calendar{ padding-left:0;}
.post_meta a{ color:#ccc; font-size:13px;}
.post_meta i{ color:#ddd; padding-right:5px;}

.single_metainfo:empty{ display:none;}
.post_foot{ margin-bottom:15px;}

/*LIST ELEMENTS*/
.list li { list-style-type:disc;}
.list1 li{ list-style-image:url(images/list1.png);}
.list2 li{ list-style-image:url(images/list2.png);}
.list3 li{ list-style-image:url(images/list3.png);}
.list4 li{ list-style-image:url(images/list4.png);}
.list5 li{ list-style-image:url(images/list5.png);}
