Yeah I don't think I've ever seen an IS300 without HIDs...
In any event, huge improvement. I will never buy another car with halogens again. I did once after being used to HIDs, the 2011 Jeep, and I was very happy to have the HIDs back when we got the 2014.

The funny thing about halogens is that, at one time, I thought they themselves were a big improvement over the earlier round or rectangle-shaped sealed-beam headlights. If my memory is correct, my (new) 1984 Mazda GLC was the first car I had with halogens, and, at the time, I was well-pleased with their night performance....they had a nice, more powerful white beam instead of the old, weak, yellowish beam of the 60s/70s sealed-beam stuff. In those days, though, the halogen bulbs simply didn't last, perhaps because of the stress on the bulbs....I replaced them on my GLC several times in the 100,000 miles I owned the car, though it was simple enough (even having to take the grille-cover off to access the mounting-screws) that I could easily do the work myself. And the GE/Sylvania halogen bulbs/light-assemblies were relatively cheap....$9.95, at the time, at Trak Auto. Later, of course, the manufacturers changed the design, for aerodynamic reasons, to the flush-surface covers and the twist-off/on bulbs that were accessed from under the hood, and you had to wear hand/eye protection because the bulbs could burst if you squeezed them too hard.

Not all JGCs have HIDs, only upper trims.

New lighting technology comes and long as the times roll on. LED is by far the greatest improvement I have ever witnessed. But Xenon lamps were pretty good as well.
I do wonder what is next. I think some sort of laser projection technology will pehraps supplant LED
As of now, I probably would never buy another car without LEDs.

No doubt LED Is now superior to HID, HID is still a big improvement over halogen.

be interesting to know when the reg took effect, because as mentioned, my BMW does the opposite from the factory. Upon signaling or turning, it actually gets even brighter with the corner lamp turning on, and the corner lamp is the inside lamp on the grille. This is the complete opposite of a DRL turning off when signals go on.

all headlight and tailight designs have to be DOT certified, maybe some turn signals are closer to DRL than others and dont require the DRL turning off. We cant even have sequential turn signals here because it requires even the individual the turn signal elements (not the whole turn signal design) to be 2200 square millimeters.

Unfortunately the refresh rate caused my iPhone to not do a good job, but here it is anyways.

In Canada DRL are standard. I see Dodge vehicles have the light out when the turn signal is going. Try this on a dark country road making a left/right turn and the left/right light goes out. Stupid! Turn blind into a corner at night, great idea.
Don't get me going about DRL in Canada. Now there are so many people driving at night with their lights out, cause the dash is lit up....my lights must be on! No the rear is still not on. There has been some proposed legislation here talking about removing the light switch altogether as there are so many people driving at night with their lights out. Car on, lights on.
