1. Flashlight: a) as 'hat', like speleologists have b) as attachment to gun or helmet 2. Jetpack As some kind of 'minimal' vehicle... no new technology needed, you just 'sit' in it and voila. Should be crafted, and maybe use Hydrogen gas to run? May be not economical, fragile, no armor, but i miss it while mining in mountainous regions... and may need some unused-yet minerals like zulax to craft?
You can have some light around using some sword or mace, perhaps blade weapons with electric damage, or using mindforce chips only equiped not using the chip. Greetings.
That works as a glow, all directions, plus not too far. If I am running, i want to see where am i running, i.e. i need directional light, as car's lights. I do not say i can't live without flashlight or jetpack, though these thingies should be too cool to not intorduce sooner or later
