How to get headlights brighter?

[White70C20]

My green 1970's headlights aren't terribly bright (old truck, I know). However, it seems like even other older pickups have brighter lights than mine. The green '70 is my daily driver when I'm at college, so I need it to be a little bit more safe. Most of the time I just drive at night with the high beams on all the time because they are almost as bright as a modern vehicle's low beams.

Are there upgraded headlights that I can buy? I've thought about the HID lights that LMC offer, but those cost an arm and a leg. I like the look of those blue lights on some modern cars, and seeing as how one of my Christmas presents was a set of LED taillight bulbs so my brake lights will be brighter, I figure I should get brighter headlights as well.

As always, any ideas and suggestions would be appreciated. Thanks!
