Any plug and play headlight upgrades available?

[71Runner]

I don't often drive at night, so it's not a very big deal, but I was wondering if there is a simple headlight upgrade available. I really don't want to dump a bunch of cash right now, as I'm unemployed. I also don't care to do an entire system upgrade with relays, heavier gauge wiring,led's etc. Can I just swap out a few headlights, or am I flirting with a wiring meltdown here?
Thanks very much.

Sealed beam Halogens (H5001-50watts/H5006-35/35watts)are a direct replacements for the original standard sealed beams. It will up the current draw on the factory wiring(about 6amps low beam and 14amps on high) but you may get away with not upgrading the system if you just do the low beams/outboards. May want to consider at least the installing the relays, save the bulkhead connectors, headlight, and high/low switches. Relays are cheap.
