If you have an '06+ 4runner (or '06 up headlights) an HID kit would be nice. I have the philips 6000k kit and it is great. I got it for about $200 online.

For on the bumper lights I recommend PIAA or LightForce. I have PIAAs and love them but I have heard a ton of good things about LightForce as well. I also really like the way PIAAs look with the aggressive stone covers. Both are about $200, for a set of LF-170s or PIAA 520s. KCs and Hellas are little cheaper, I think, but the ones I've seen weren't as bright as PIAA or LF.

As to which you should get, that really depends on whether you want the extra light with your lows and all the time, or just when you have your high beams on. Also the '06 thing for HIDs, it's a bad idea to put HIDs in the 03-05 reflector without doing a retrofit.
