You need to include another xml in your drawable, and call it mr_ic_media_route_holo_light.xml. The default content for that is:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:state_enabled="true"
            android:drawable="@drawable/mr_ic_media_route_on_holo_light" />
    <item android:state_checkable="true" android:state_enabled="true"
            android:drawable="@drawable/mr_ic_media_route_connecting_holo_light" />
    <item android:state_enabled="true"
            android:drawable="@drawable/mr_ic_media_route_off_holo_light" />
    <item android:drawable="@drawable/mr_ic_media_route_disabled_holo_light" />
</selector>

and update the content of that to point to what you would like. Note that the default version of this file (and the referenced drawables) can be found in your <SDK-DIR>/extras/android/support/v7/mediarouter/res/drawable.
