<context><p>Create a new instance of Extended Light API is using <codeph>NewL()</codeph> or <codeph>NewLC()</codeph> method.

If the instance require the status feedback from the lights, derive the instance

of the API from the <codeph>MHWRMExtendedLight</codeph>.</p><p>The following

code demonstrates how to create an instance of Extended Light API:</p><codeblock xml:space="preserve">#include HWRMExtendedLight.h //Link against HWRMExtendedLightClient.lib.

class CNewApp : public CBase,

                public MHWRMExtendedLightObserver

        CNewApp();

        ~CNewApp();
