What's the etiquette for lighting, esp. off road? Can we please adopt some?

I get it, we all love lumens, are very impressed with the size of each others' lumens and it's everything with the lumens. But in October 2012 we are long past the point of lumens=IQ. Every moron out there is sporting tremendous lumens.

So guess what, from now on all the scheiss is going to be about courtesy to your fellow lit-up-morons and not melting the retina of everything in your godforsaken path.
