JimnyJeep has just bought a set of Ultima 175's and we are about to wire them up. I run a pair of Narva Targa 200's which use the same bulb and these lights are extremely bright.
I'm pretty sure Narva quoted us $165 for the Ultima 175's but AutoPro sell them for $125. Very, very good value for money. I can't justify paying $400 for a pair of comparable IPF's which don't light up much more.
