That link is for "W5W" & the original link in the 1st post was for "W9W"; Oddjob is asking if there is a difference between the two. Perhaps the "W9W" was a typo, as I too can only find "W5W" now.
Also, Hapa88, is there a difference in color in the 6WLED bulbs you had & the new 25-LED bulbs? {ie. are both crystal-white w/ slight UV-like halo?}
Thanks buddy! Just wanted that type of affirmation before I grab some for the front-bumper combo' lights (NSX application) & license-plate lights (for other vehicles in the stable).The 6WLED bulbs had a slightly bluer tint from my recollection, but that could be just because the 25 LED was brighter and washed out more of the bluer color. The 25 LED has a very slight blue tint (maybe like 5000-5500K). Whereas the 6WLED was probably closer to 6000-6500K.
I believe that resistors are required for bulbs that are the turn-signal lights. LEDs will need resistors in them or the turn-signals end up blinking super fast.
took 2 weeks to get after ordering them on ebay. The fitment finish is not so good as the bulb is loose and can move around. Its a problem if it moves around in lens as it will affect the aim and brightness and if it pops out into the lens. They are bright matches the color of my 6000k HID headlights. However they are not bright enough to be noticeable on a sunny day to use as day time running lights.
My fiancee just picked up an IS250 so I've been on their forums a lot and came across this. Someone did a quick 194 size LED test and comparison. I recommend you guys check it out! Some good info a pictures in it.
