Iv got 6000k hid low beam and std highbeam, but with artic blue globes.
Puts out a fairly white light, not too much blue, just a kinda tinge and no yellow at all.
Have lasted fine the past year and a bit/40,000kms, bit of contry driving at night to gero, out to mullewa & bunbry & that and have been alright. you would really need somewhere to put spotties if u did heaps of night time/wanted more light/arent as game haha. Passed pits with them
mine are aimed pretty low tho, so low beam is great for just infront, but you need hi beam for the distance.
And i agree with rossco, they light up signs way ahead off you, like in front of traffic, but not really anything that isnt white or reflective or untill your close.
I dont rekon pre 05 subies have that greater lights std...but i did grow up thinking that anything less than four spotties was average haha
