Don't have the vehicle currently at my disposal to check. Are the low beam bulbs H11a or b's?
Low beams are H11

A simple web search turned up that Toyotas are primarily H11A style. Took me less time to find that out than to post the answer here.

There was no passive about it, or me for that matter. It was literally the first thing that popped up for me when entering "H11A vs H11B 4Runner"Your passive aggressiveness means nothing to me. I spent 30 minutes searching with no definitive answer which lead me to making this thread which will now aid others in the future.
Ohhhh there are different As and Bs for Halogen and HID. Interesting, learn something new every dayOP are you looking for halogen or plug n play HID bulbs?
Halogen - H11. As Swamp mentioned a halogen H11b has a totally different electrical connector than the traditional H11.
HID-wise, if the seller offers an option for A or B, it's usually B. Some PNP HID bulbs are only offered as a single H11 base, like Xenon Depot, but luckily the return wire and tabs are at the correct position for a projector light assembly. A H11a will fit, but the return wire will cause a "shadow" on the beam pattern.
The widest notch on your headlight pic appears to be in the 11ish o'clock position, so it should be B.
