foglights in the grille?

Upgraded wiring with relays for sure, no matter what lamps you wind up with. There are at least two members on here who can provide you with a parts kit or a built-up relay harness for your headlamps, (CrackedBack and myself) -- don't buy cheap crap, it's not worth risking your life over.

The Night Hawks are the cheapest passably decent headlamp to fit. There are headlamps (much) better than the Night Hawks, but they generally cost (much) more; on the other hand you don't throw 'em away when they burn out, you just replace the bulb. Next step up from Night Hawks is a pretty big step, without spending a mountain of cash; that's this headlamp with these bulbs.
