+<a name="androidLightsIntroduction"></a><h2>Introduction</h2> 
+ 
+<p>Android defines a user space C abstraction interface for LED hardware. The interface header is defined in 
+<code>hardware/libhardware/include/hardware/lights.h</code>.
+In order to integrate LEDs with Android you need to build a shared library that implements this interface. 
+
+The types of logical lights currently supported by Android include:
+<ul>
+<li>Backlight</li>
+<li>Keyboard</li>
+<li>Buttons</li>
+<li>Battery</li>
+<li>Notifications</li>
+<li>Attention</li>
+</ul>
+</p> 
+ 
+<a name="androidLightsBuildingDriver"></a><h2>Building a Lights Library</h2>
+<p> To implement a Lights driver, create a shared library that implements the interface defined in <code>lights.h</code>. You must name your shared library 
+<code>liblights.so</code> so that it will get loaded from <code>/system/lib</code> at runtime.
