darktiger,
That should not be a problem. My Lexus IS300 has the same functionality. My HIDs stay on 30 seconds after I lock my car. My HIDs came from the factory and there should be no problems leaving them on for the 15-30 seconds. If it bothers you, you can lock the car again and the lights will turn off.
The one bad thing, common to most cars, is if you leave a door open or the trunk open. The lights will stay on until all doors and the trunk have been closed.
