No offense intended, but I hate the silverstars. Stay away from anything tinted, I don't care if the blue makes it look fancier. Any tint is just reducing the amount of light being thrown, and even though it "looks" brighter, it's simply a placebo effect. Also, all sylvania bulbs are made in china, screw china. If you want standard halogen, the one I've been using lately is Phillips. They have a variety of standard and "+" brightness bulbs. I've been using either the +60% or +100% bulbs in stuff, depending on what was available. In my youngest brothers '11 CTS, the only available one for the high beams was the standard brightness, and it turned out to be the exact, actual OEM bulb that Cadillac puts in them. And they aren't overpowered or +wattage or any of that nonsense. My understanding is that the increased brightness comes from a higher quality, tighter wound filament that's able to more efficiently make use of the available current, and possibly also creating a tighter, more focused pattern of light. Also, Phillips are made in Germany. If it involves quality manufacturing, you want either USA, Japan or Germany.
Now, if you want to talk upgrades, there's been some amazing progress in the world of LEDs the last few years. There's a lot of stuff out there. At the moment, I'm interested in the stuff being made by OPT7. I plan to try out at least of set of low beams, and possibly a set of high beams from them. The previous generation are the Fluxbeam, which are about $80 a pair on Amazon, and the current gen are the Fluxbeam X that just came out, and are $100-110 I think. I've normally been against putting HID or LED into our older style headlights because they don't throw the light correctly, but supposedly the more recent LED stuff is starting to get be able to cope with this and work well without blinding oncoming drivers. I'm by no means an expert on LEDs, but the technology has finally reached the point that I'd be willing to take a stab at it.
