I like the blue lights, as long as they arent tinted too much. From my understanding some of the bulbs have a different gas mixture in the bulb, and are more powerful.
I had some hyperindustries ones that looked retarded and burned my sockets.
I replaced the sockets, bought some best buy xenon white lights and they looked gay, too dull. I then bought some from a local audio shop around here, i want to say Nokya or something brand and I liked them. Shines on the road 95% white, has a bluish tint, and is VERY bright with minimal change in wattage. Thats how i am to understand it. Those "HID immitation bulbs" actually are usually AS bright or brighter than the stocks. Here is a picture of my old best buy lights (they had a brand i just forget, whatever bb sells)
I personally didn't like silverstars installed in my friend's 98 mountie, but most people do like them. The aftermarket "HID immitation" FOG lights you buy match the silverstars nicely, however.
Silverstars are brighter it's just not my personal taste. See what you think of this (not a good picture but hey)
P.S. the fog lights are LUKS rainbow HID so don't compare that way, they were almost identical.
