I have been swapping all my old headlights to Philips Xtreme Ultinons. They're really pretty good, and mimic the halogen really well.
I had changed out my street triples H4 OE bulbs for some Sylvania's, and the second ride to work the low beam filament broke on one bulb. I looked to see how much hid retro fit would run and decided I didn't want to spend 600+ on a professional job. Ended up running across these, I believe in a 675 forum, and have been incredibly happy with them. It's kind of reassuring to me too have a brand name on it, figured they would have more to lose reputation wise. Who knows. Anyways, installed some in my wife's Colorado reflectors next, and they really did wonders. Installed some next for my low beams in the ST. After a lot of struggling with it. Thought the glare cap would have to come off because I couldn't quite get it in there. So took that off, still wouldn't fit with the passive heat sink in back. Ended up needing to shave off part of the rubber boot ring to get it to actually go in all the way and lock in. Glare cap fits with it. Rubber boots fit with it as well, just bulges a little where the heat sink is. Accurate spread, good cutoff, but nowhere near as clean as projectors. I think I will end up spending the cash to retrofit hid projectors on this car and move these down to the fog lights, but this works well in the interim
