I read something the other day saying Philips and Sylvania both have come out with LED replacements for 7" round sealed beams (Sylvania is calling theirs "Zevo") and launched them at the SEMA show. I looked around on the web and didn't find anything more specific or any pictures. It will be interesting to see what these lamps actually are. Will they be in-house design/build? In-house design/outsourced build? Or just somebody else's lamps repackaged (GE is selling Truck-Lite's LED sealed beams, for example). Guess we'll have to wait and see.
The LED 1156/7 bulbs you saw are Philips-branded? That's interesting. I don't see anything about those, though it wouldn't surprise me for a couple of reasons. For one, Philips already has some LED replacements for various dome light bulbs (DE3022 and C5W stick in my mind, though I could be wrong). And Philips, like Osram, is working hard in Europe on real, true, safe, legal, proper LED bulbs. They're nothing like any of the "LED bulbs" you can find now. They have a high-power LED in the cap (base) of the bulb, and a light guide configured to emit light at the same location and in the same "shape" as a filament bulb. I've seen polar plots of the light output of filament vs. LED, and it sure appears they've managed to whip the light distribution issue.
These will put out white light except for the ones to replace bulbs that are supposed to put out amber or red light, because under UN Regulation 37 it's not allowed to have bulbs of different output or power characteristics be physically interchangeable (though as a matter of practicality this is not applied to bulbs below about 10w, hence R5W and R10W are physically the same, and the white W5W and amber WY5W are physically the same...). So for that reason, in the ECE markets they won't be selling white, red, and amber P21Ws, just white P21Ws and amber PY21Ws and red PR21Ws, each on its own unique base just like the filament versions. For now, they've got C5W and R5W pretty well ready to go technically, but it's going to take awhile for new regulations to be written or old ones amended to permit them.
Signal bulbs aren't directly regulated by Federal law in the NAFTA region like they are in Europe, so it seems likely we might see this product line here before they see it over there. But unless they are way very much farther along in the development than they were two months ago, it's going to be awhile before we see this kind of bulb with the output needed to replace 1156, 1157, etc.
9011 and 9012 don't surprise me, there are enough vehicles on the road using these now that there's a market for readily-available replacements.
I agree with you that Philips' packaging and product claims tend to be more honest than those of another major brand. Also, Philips' product line has a lot more genuinely better-performing bulb options, compared to that other brand that has mostly different flavors of bling.
