Oh man I would prefer to stay out of this will attempt to clarify a few things.
First lights at boat ramps. Most of those light are probably solar powered, as such the laws of physics come into play with how much light can be produced with a given set up. Throw in the fact that over a certain $ cost it becomes a logistical nightmare to purchase relatively low cost items without going through many hoops and greatly increasing the cost and time required to procure. The system in place for purchasing is changing but it is slow. Some of the solar set ups are designed to come on say at dark and go off at daylight, that is fairly rare, since if the light is very bright it takes more power and quickly drains the batteries, which will kill them in a short time. Others put out less light and will last longer, better technology allows for a step down to lower power use unless movement is detected, then it will go to full power again. New technology as always is more expensive, see above comments on purchasing stuff.
Firearms. It is a rule within Title 36 CFR that prohibits the carry of firearms on COE properties outside Law Enforcement, hunting, or at designated shooting ranges. It is not a state law. The best I can say is be patient, the wheels are turning to update Title 36 CFR. However as with all things Government the wheels turn slowly, it is expected that the change will essentially mirror the state laws in effect for each lake, however won't know until it is published for comment in the federal register.
