One should not speak of "lights" that arouses possibly false expectations. The glowing part or glows (Name: "glow"), but that makes it permanent. There is no Nitestik, you have to not only illuminate brightly. Thus, the Trigaglow would not brighter, but he will not even darker, more than over the years by isotope decay. The purpose is completely fulfilled, it marks something in case of darkness. For more, it is not intended, you can thus illuminate anything or even read. For example, if the key falls into the grass or the off flashlight is in the tent, you can see beautiful in the dark, where these things are. Here the trailer is so small that it does not interfere. The brightness is but at least so great that I would perceive it at night next to the bed as disturbing. From me therefore a perfect score!
