Does anyone know what sort of headlight globe the 4GS is shipped with? Have the standard D4S HID single lens fitting. All I can find is a Lexus part no but no reference to who makes it.

Reason for asking - I'm considering changing one to an Osram xenarc night breaker unlimited to see if they're brighter, they claim it outputs up to 70% more light. If the Lexus globe is already a superior rebadged globe I won't bother.

When you say globe do you bulb, if so then Osram is good I have not used it but when I had my GS I had the Philips Utilnon 6K which were pretty good. Stock is Philips.

Stock is Toshiba-Harison 4300K

I swapped them out for Osram Cool Blue Intense bulbs which are slightly bluer white, but still white at 5000K.

Thanks! It looks like a basic bulb so the Night Breakers should be better than OEM

I'm sticking with OEM colour (or close to @4350K) and hoping for an improvement!

Awesome. Did you find the light level increased?

In theory, 4300K gives you better visibility in rain/snow/fog, but in good weather at night, 5000K is the sweet spot. As you go higher in temperature, the light output starts to drop off.

Yes especially when I upgraded to the 5000K as the lower the better light output.

While we're on the same topic. How does the bi-xenon headlights work on the 2016+? I know it's LED and on the old HID there's a flap that moves when u switch to high beam right? Is it the same for the new LED light? This is not the triple beam one.
