2010 IS250 - What type of headlamp bulbs do I need??
I am attaching photos. My driver's side low beam is out and the tiny white bulb next to it is out also. Can someone tell me the bulb numbers? How do I know if they are HID or halogen??

I would like to say you need D4S bulbs as you have HIDs, but it's obvious someone did some headlight work and switched out the little halogen light next to the high beam for an LED, and the low beam looks a bit bluer than usual unless someone swapped them out for a bluer D4S bulb (such as CBI's). As for that little bulb, it's a 194 bulb.
Easiest way to determine if the lows are OEM HIDs is to pull out the bulb. If it looks like this, you have OEM hids and you'll need D4S bulbs to replace them with (I'd recommend replacing both at the same time). An aftermarket kit will have wires running off the bulb, unlike a D4S/D2S bulb that just has the socket for the connector (as the picture I linked above shows), in which case, you'll need an H11 bulb to replace it with.
Definitely more towards a 6000-6500k temperature so they could have been swapped out - What Zmon said though you won't know until you try to take the bulb out -
Thank you both so much! Zmon, I'll check the bulb type and then order off of XenonDepot. I've gotten bulbs from them in the past on my old Lexus. The little bulb is definitely a 194 though correct?? It's just the low beam that I need to be sure whether it's a D4S or an H11, correct??
