I have had my ralley lows and HIR highs installed for about a month now. They really got a workout driving arround curvy mountian roads in the catskills a few weekends ago in the dead of night.
I think they are fantastic. With the lows I see no need to consider HIDs and the highs remove any need I might have had for driving lights.
Keep in mind that I replaced these bulbs before doing any night driving of consiquence with my Legacy and my point of comparison is a bugeye WRX.
I now need to upgrade the fog lights since I can't even tell they are on anymore. My main (well only) use for them is durring winter to get a better idea on road texture (is that ice, salt or snow I am driving over)
Also, trimming the HIRs took only a few mintes with a pair of wire cutter pliers.
