Bullet image on latest news posts in side widget

Hi Guys

With you help I sorted the widget in my footer, latest news. Now I need to use a image for my side bar widget, putting a bullet point by each of the news/post links.

This is what I used for the footer

#recent-posts-4 ul li, #pages-4 ul li, #pages-4 text-15 {
list-style-position: outside;
margin-left: -20px !important;
width: 190px;

I thought that this would work
#recent-posts-3 ul li {
list-style-image: url (http://www.integra-associates.com/wp...quare_lb.gif);
margin-left: -20px !important;

but nothing seemed to work

I also tried

div.widget_pages ul li {
list-style-image: url (http://www.integra-associates.com/wp...quare_lb.gif);

But again nothing worked and nothing broke

Any ideas?
