The second light we use all of the time is a headlamp (midnight bathroom breaks are SO much easier with a headlamp!).
Ahh, yes, a good light is SO important for camping. We always use two types of lights when camping: a solar light and a headlamp. We have a wonderful, inflatable solar light that is great for hanging from the roof of the tent (works great when getting ready for bed or playing a game at night in the tent). We love it because we throw it out on the picnic table or on the outside of the tent during the day so it can charge back up. This is the solar light that we use, and we have been so impressed with it. We've had it for about 3.5 years now and it's worked great. The second light we use all of the time is a headlamp (midnight bathroom breaks are SO much easier with a headlamp!). Petzl is a common brand that we have used in the past. Here is a link to one of their cheaper models, for around $30.  You do not NEED both lights – you would be able to make do with one or the other. These are the products we use, and you can make the decision of what you will need for your camping trip. If you are not keen on spending money on a light, a good old-fashioned flashlight will get the job done, too! Just be sure to bring along some fresh batteries before you leave for your trip.
