given the age of the car, my first guess is that the bulbs are going bad. iirc, they should be d4s bulbs. if you take one out and look at the little capsule inside, if it's almost entirely black, it's a good first step(they start clear, and then slowly get blacker as time goes on)

the fact that the height adjuster in the car works tells me that the previous owner spent time doing it right, though the boomerang not working is suspect...
Thanks. I will pull the bulbs and look at them. If nothing is obvious I assume I could swap them left to right and see if the problem follows the bulb, correct?

Also, doing a little more reading, it sounds like there was a resistor on the FRS that has to be removed or it can damage the BRZ DRL LED's. I will look for that resistor when I get into it but am wondering if the boomerang LED's can be bench tested? Could I pull the headlamp assembly off the car and connect the proper + and ground wires to a 12V supply to verify they are still functional? Not sure which wire(s) but assume I can find on a wiring diagram somewhere. Just not that familiar with LED's and if they run off standard 12V supply.
