That is a really interesting collection of new Hella modules. The polycarbonate lenses do have the advantages claimed, but they also have the usual durability disadvantages not mentioned in this promotional brochure. That high beam + turn signal module is an interesting mix of functions. I will be very interested to find out what category of front turn signal it is homologated and certified as. Turn signal minimum-intensity multipliers in both the US and UN/rest-of-the-world regulations are all keyed off distance between the turn signal and the low beam headlamp, with no mention of the high beams -- the reasonable assumption being that if your high beams are on, there's nobody in front of you to see the front turn signal anyhow. But these aren't assemblies for one specific vehicle that will always be mounted with the high beam-ring turn signal a known distance away from the low beam, so I would expect/hope to find these front turns designed to conform to the highest minimum intensity, in (likely) case they are mounted so the turn signals are closer than 4" from the low beams.
As for light color: I do wish the auto and lamp makers would drop the fascination with blue, e.g., designing optics to create a big, prominent blue fringe/flash at the outer extremities of the beam. The effect is obnoxious and potentially dangerous in traffic. And we do have that data from UMTRI finding that for any given intensity, bluer-white light creates a little under 50% more sensation of glare than a yellower-white light. Which means, at least in theory, by designing LED headlamps to produce yellower-white rather than bluer-white light, we could have either 46% less-glaring headlamps by keeping the beam intensity the same, or 46% greater beam intensity by keeping the glare the same, or some combination of those two.
Unfortunately I doubt there will be any regulatory or voluntary industry action in that direction; the marketing is all built on bluer-bluer-bluer. But I think it will be interesting to see how this evolves. I wouldn't bet on it being a simple bluer-bluer-bluer elevation game forever. LED street light specifiers, as has been detailed in discussions elsewhere on CPF, after initially being enthusiastic to get the maximum CCT (5500K...6000K...6500K...), have backed off to what is being called a "neutral white" of around 4000K for optimal all-around effective visual performance. I will say this: On the night drives at the VISION Congress last month in France, the range of apparent color temperature on the roadway from various LED headlamps all claiming "6000K" was huge. Some of the headlamps seemed to put out downright blue light; others gave the impression of what could reasonably be called a central or neutral white. It was system-by-system, not lamp-by-lamp, which indicates the LED industry has no trouble binning LEDs for optimal color match. But I do think we might see changes in the way light color and color rendering are measured and expressed, because today's LED light sources really do have some characteristics that were just not on the radar when existing rating scales like CRI and CCT were devised and standardized. Nothing as drastic as wholesale scrappage of those scales, but maybe some adjustments and expansions and supplementation.
In the meantime, I wouldn't object to the light color of a lot of the "6000K" LED headlamps I've seen. Yes, I'd rather have a selective yellow fog lamp, but nobody makes a selective yellow LED phosphor. There's no such thing as an LED that puts out selective yellow light. Could put warm white LEDs behind a colored lens, but nobody's doing that, either. Fog lamps are generally used for cosmetics, anyway, and I am guessing this is in part Hella's offering in competition with Osram's LEDriving line, which includes some really very nice modular fog/cornering lamps, fog/DRL, and DRL.
