I just bought a couple of battery operated portable LED lights from Fish House Supply. They are pretty cool, they are small enough to carry around in your pocket and when I want to use them in my portable, I just stick them to the window flaps of my otter with the velcro back that is on them. I can't give the website but if you would like to look at these do a search for Fish House Supply. Then click on to there 12 volt lights & accessories page.
