you cant compare halogen with hids,its day and night,i have a set of helios bi-xenon 6000k,and its amazing,i ll never go back to halogen,light is brighter,wider,longer range,everything is better,and in bad weather,you see the road marks and anything much better than halogen....for my opinion,in 2006-2007,it should be a security standart for all automotive companies....its going that way,since many companies gives the customer the option,before,only bmw and mercedez where hids,but now,almost every companies have at least one model with the hids option....
so,dont question yourself,get some,you wont regret it...(first)
