Why doesn't Camp Pendleton have any lights on main roads?

I've been here for a while and I've noticed that main roads like Vandergrift,19th st and the whole base in general has very little light, especially in certain areas around the mountains. It can get extremely dark out there, and when the fog rolls in, it's extremely dangerous.

Just curious as to why they don't put lights on these long stretches of road? Would hate to see a nasty accident take someone's life because of darkness
