I found an atomic nightlight in a missile silo. you could also use the vehicle construction to build a solar lamp. 1 tile wide lamp will charge slowly and drain kind of quick. make it bigger though, or with better solar panels and it will charge faster. making it bigger can also allow for more rechargeable batteries which in turn makes it last longer. youll need a control to turn it on and off. instead of using headlights though, you can try to find a floodlight. flood light is great.
but still, lightstrip or atomic nightlight are best if you can find them. a lot less work, but the lightstrip has to be taken apart and rebuilt when it dies.
