Picking up my FX 3 Disc in a couple days and trying to get a good idea what are necessary accessory purchases. This is my first real bike purchase ever, so I'm still figuring this out.

Are tail lights a must for my daytime riding? I'm looking at the Planet Bike SuperFlash, but I wouldn't mind spending in the $50-$60 range for a better one if it's worth it and you have recommendations.
