I built a little "bull bar" for my bumper and I'm looking to add two lights to it. I'm leaning towards the Hella 500's for their price, and their general quality. I do understand the difference in patterns, but I'm still undecided. I'm kind of leaning towards a "fog light" pattern, figuring that it's more important to be able to see the stuff close to/around me. So, my question to you is... If you were to add only two lights to your rig, would you opt for "fog lights" or "driving lights"?
