I had these in my old Corolla (which are notorious for their awful head lights) and noticed a huge difference in output over the old Sylvanias in it. The light was much clearer; they won't look white, but they have a lot less of the yellow you expect from standard bulbs. However, as the packaging says and I was warned, this comes at a cost; they are shorter in life than your normal standard bulb. They are really pricey though, and I'm not sure they're worth the premium over the normal Silverstars.
I'm probably going to put GE Nighthawks (not the Nighthawk Platinum) in my truck because I've used them for smaller bulbs with major improvements and they seem to be a nice mix of value and brightness while the reviews I've read mention no major shortening of the bulb's life span.
If your head light lens is cloudy and reducing output you may want to consider using a kit to polish it before changing bulbs, though these have varying degrees of effectiveness; the Turtle Wax kit I used cleaned up my Corolla and my father's Suzuki very nicely, but the Corolla has a lens like the Dakota, and after about 4 months it seemed to be starting to cloud a bit again, while to compare the Suzuki (which simply has a clear plastic lens) is still clear. It will eventually cloud up again no matter what kit you use, but some are better than others depending on the amount of cloudiness they get off in the first place and the sealing compound they use. The composition of the lens itself is also a variable.
Ya thanks for the info I kept looking after I posted this and also found sylvania cool blue headlights for quite cheaper as well but even the ultras are pretty good considering I was wanting hids which would have costed 124 dollars
Some folks say they what more light from the bulbs but I have found that the SSU's are just right for standard lighting. If the headlight housing is adjusted correctly, the SSU's put out more than enough light without blinding on-coming traffic. I had the SSU's in my fog light housings but they were way too bright.
FWIW I put Nighthawks in my front housings (head lamps, turn signals) and they are much brighter. My turn signals/parking lights are vastly superior, and the Philips that were in it can't even compete with the light output with the Nighthawks. I would say an easy distance gain of about a yard head on, and a good foot and a half to the sides. The clarity seems to be very close to the Ultras too, but the output isn't quite as intense. For $20 though (and they have a $5 rebate on them, so unless you're a dolt like me and forget to clip the UPC before throwing them out they're only $15)... I don't think you can beat them for value.
I have also used the Sylvania Silverstar bulbs but not the Ultra as with what was said about the life of the bulb. The ultra has a lot brighter output with a lot shorter life, I use the step above the base Silverstar bulb and have had a very useful life of around three to four years depending on nighttime usage.
HID's are too pricey and I feel that they are not worth the cost of the upgrade as the low cost kits only have Low beam ONLY bulbs, That is just my 2 cents worth.
Sorry I didnt get on and chime in. Been very busy.
Don't laugh but I use $11 cheap ebay headlights. Barely blue in appearance if you look at the truck. And totally white looking at the road driving. They do not last as long as these headlights but they are WAY cheaper. I actually gave these headlights away to my friend once I found out about these cheapos.
