The bang-for-buck LED 7" round headlamp (no need or benefit for relay harness because low amp draw) is
this one; details on what makes it so are
here.
With halogen headlamps you'd deffo want to put in a relay harness; our own FABO dude
@crackedback makes excellent ones.
For halogen lamps: the Hella items RRR linked are certainly better than the mountain of off-brand garbage all over the net, but even so, those Hellas have never been very good, and they've slipped badly in recent years; if you're rabid for Hella lamps, the ones you want are
these. The Toyota kit is a better price on better lights.
Bulbs: do not just point-and-pick on wattage. Even with a relay harness, for a sturdy collection of good reasons overwattage bulbs (higher than 60/55w) are not the wise pick they might sound like. And while there's no magic bulb that turns crummy headlamps into good ones, there is a huge range of performance even just within spec-wattage bulbs, there is a huge range of performance. take a look at
this. And don't be fooled;
the "LED bulbs" now flooding the market (like "HID kits" before them), claiming to convert halogen headlamps, are not a legitimate, safe, effective, or legal product. No matter whose name is on them or what the vendor claims, these are almost all a fraudulent scam. The overwhelming majority of them are not capable of producing the right amounts of light, nor producing it in the right pattern for the lamp's optics to work, let alone work well.
Whatever lamps you wind up with, their aim is by far the main thing that determines how well you can (or can't) see at night, and how much glare you're throwing around. Pretty good odds your headlamps (and fog lamps, as applicable) aren't well aimed; even many brand-new vehicles have poorly-aimed lamps. And if you remove and replace the lamps, even with the same ones you removed (let alone different ones!), the aim won't carry over after replacement, even if you put back the same lights you took out. Plus, there's a bunch of bad how-to-aim info to be found on the web (and on headlight boxes, sad to say).
So, ya gotta-gotta-gotta make sure your lamps are aimed carefully and
correctly per the instructions
