Sylvania Silverstar Update
These bulbs are significantly "whiter" in appearance than the stock bulbs... Not the blue tint you see on some vehicles, but white. As to extra brightness, to me they are about the same asthe stock bulbs,just whiter.
Now to the bad. I have had three passing lamps burn out during the four month period I've been running these bulbs. Yes, I avoid touching the glass when I install bulbs and even wipe them down with alcohol to insure there is no grease orfingerprintsprior to installation. The first failure occurred during a ride in the rain and now the second failure (both passing lampbulbs on the same day!) occurred two days after a ride in the rain. There is no evidence of water inside the light housing, but if you've been inside these lights you know the housing is not waterproof, but rather "water resistant". Additionally, the fuse did not blow and there is no evidence of any type of electrical short. The bulbs just quit working and I think it is just a coincidence about the rainy rides.
What caused the failure? I'm not sure. Maybe the extra "wiggle" of the unbalanced motor at idlewas more than the filiment could handle.I've reinstalled the stock bulbsand everything is up and running again.
One thing of note, when I bought these bulbs Sylvania didn't make a true replacementin the Silverstar line. I'm not sure if they do now. The cannon plug for the stock bulb connects from the bottom, (i.e. 90 degree bend), while the 880 connection goes straight back... Same wattage (27 watts), same everything else just a different connection angle. It is tight, but they fit.
I've had Silverstars in my Ford F-250 headlights and fog lights for years with no failures. I run the truck's headlights anytime it is in motion to give me daytime running lights, yet they stillhaven't failed after all of the hours of use. I highly recommend Silverstarsfor auto applications and so farthe H4 mainheadlight is good, butfor some reasonSilverstars haven't faired well in my passing lamps.
