Yeah, I'd never seen a separate parking light like that before. Found mine by accident to be honest, but glad I was able to help. You might just have 2 burned out head lights. I'd check the fuses and see if the lights are bad. My Legacy had both corner brake lights burned out and I didn't even catch it right away, so it's possible.
Bad CV joints will manifest as a clicking sound on turns. Usually they fail if the rubber boot rips, which cause the grease to run out. Over time the joint fails and you'll hear clicking (this means they are toast and need replaced). If ignored TOO long, they separate and break. On FWD cars, you are dead in the water. On AWD, you might be able to limp it home.
On mine, I actually lost the clamp that holds the boot in place, and *some* grease was seeping out. Appears to have happened before buying the car. I was able to get a replacement clamp from Auto Zone designed specifically for CV boots. I put some fresh bearing grease in the boot, then tightened it back in place. Thankfully caught it in time. Walmart oddly enough sells a bag of steel clamps that appear to be the same. I bought some as back ups, but dunno if those stores exist there. Definitely get them taken care of. Turn your wheel hard right, then check driver side front, hard left for passenger side. Look at rubber boot right behind wheel for rips in the crease. Grease on the boot is a tell tale sign it's leaking.
Still not sure about bushings on those. Only bushings I can think of might be on the A-arm or for the strut bearing. Maybe an Impreza person will speak up.
