Can one of these units independently control two garage doors? The manual doesn't mention that at all.

Yes. I have a 2014 GMC Acadia, a 2006 GMC Envoy, and two Liftmaster 8355W garage door openers. One bridge is all I needed. Just keep repeating the programming instructions until all the buttons are completed. I only had to program each vehicle button once and then all four buttons worked.

Does anyone know what the "indicator light" is on the repeater? When plugged into the AC socket, it flashes rapidlly in a random pattern.

Yeah, I was confused as well, that yellow LED on the wall unit (repeater) is not constantly on, but pulses in somewhat random fashion, was thinking the unit is dead, but that is how it is I guess. I plugged it in the ceiling outlet to shorten the distance to the garage door opener...

I have a new Homelink Repeater. Why does the LED constantly flash and transmit causing same LED flashing on motorhead when it should be 100% idle?

Repeater is the link from car to door opener, they communicate constantly. Codes are always changing so someone doesn't steal your opener code.

Does this have to be in a specific location within the garage?

I’m not sure if that’s a requirement, but I have mine plugged into the same outlet as the garage door opener and it works great. It would definitely be a safer bet to plug it in closer rather than not.
