worked it out.

replace the header template in the lightweight style with:

<vb:if condition="$vboptions['ls_page_title']!=''">
	<div align="right">
		<vb:if condition="$vboptions['ls_default_style_link']==1">
			<a class="toplinks" href="{vb:raw vboptions.ls_navbar_home}?{vb:raw session.sessionurl}styleid={vb:raw vboptions.ls_default_style}">{vb:raw vboptions.ls_default_link}</a>
		</vb:if>
	<vb:if condition="$show['member']">
		<a class="toplinks" href="login.php?do=logout&amp;logouthash={vb:raw bbuserinfo.logouthash}">{vb:rawphrase log_out}</a> 
	</vb:if>
	</div>
	<div class="header" align="left">{vb:raw vboptions.ls_page_title}</div>
<vb:else />
	<div class="logo" style="text-align:right;">
		<vb:if condition="$vboptions['ls_default_style_link']=='1'">
			<a class="toplinks" href="{vb:raw vboptions.ls_navbar_home}?{vb:raw session.sessionurl}styleid={vb:raw vboptions.ls_default_style}">{vb:raw vboptions.ls_default_link}</a> 
		</vb:if>
		<vb:if condition="$show['member']">
			<a class="toplinks" href="login.php?do=logout&amp;logouthash={vb:raw bbuserinfo.logouthash}">{vb:rawphrase log_out}</a>
		</vb:if>
	</div>
</vb:if>

<vb:if condition="$ad_location['ad_header_logo']">
	{vb:raw ad_location.ad_header_logo}
</vb:if>
