Okay im thinking about replacing my HIDS. Apparently there is higher wattage ones? like 55w, 70w and 100w. Does anyone know about these? And would putting 8000k's in the low beam, 4000k's in the high beam and 3000k's (yellow) in the fog lights be the best option for practicality and performance? I drive mainly on country roads and i think that ill like to have the 8000k's for looks when im driving in town.

I dunno what do you guys think. Im so confused with the wattage.

35w~55w, RTA says that that's ok so it won't blind oncoming traffic, but since fto's have projector headlights, 55w will suffice.
