That's a topic subject I never expected to see. I thought the lights were excellent, as good as the ones on the old Vee/Wee even.
As for the relays, the idea is that you power the headlights via relays that put power on the bulb terminals directly from the battery connections using thicker gauge wire. This then means there is less (almost no) voltage drop for the bulb and they burn at their full potential. If you're not electrickery savvy it's easiest to just but the kit from Eastern Beaver, installation is decently straight forward, it's very neat and you can remove it when you sell the bike.
Alternatively you can start with better quality bulbs. The Philips bulbs are usually getting good reviews, I use the MotoVision ones myself, they give a slight orange tint which makes your headlight reflectors look orange and it seems to get me noticed better than a high vis jacket ever did. Osram Nightbreaker bulbs are also frequently mentioned. Try to stay away from bulbs that have very white/blueish light, they look brighter than they really are to people coming towards you and might cause them to flash their hi beam at you, you can't afford to be blinded when all you really want it to see better. I hardly ever get flashed at with the orange looking bulbs.
