<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
    {
    public:
        CNewApp();
        ~CNewApp();
        void ConstructL();
        static CNewApp* NewL();
        // from MHWRMExtendedLightObserver
        virtual void LightStatusChanged( TInt aTarget,
                                         CHWRMExtendedLight::TLightStatus aStatus );
    private:
        CHWRMExtendedLight* iLight;
    };
</codeblock><p>Without a notification, the instance can be derived from <codeph>CBase</codeph> and
created using <codeph>NewL()</codeph> or <codeph>NewLC()</codeph>.</p><codeblock xml:space="preserve">CHWRMExtendedLight* light = CHWRMExtendedLight::NewLC(); // No callbacks</codeblock></context>
