Orange light is rear fog. Subaru's don't have an idiot light for daytime runners.
No, Subaru have no option to activate DRL's.
+1 for getting a decent aftermarket kit wired in properly. This means the lamps must turn off when the headlamps are on.
Yeah it's a pretty easy drive. I've done it in a single tank of gas in a WRX before. It's a wicked weekend too. You don't relise how much fun it is till you get there and experience a MegaMeet first hand
