Sonata Parking and Tail Lights
 

I have a 2000 Sonata GLS. Soon after I bought it the right front parking and right rear tail light went out, directional and hazzards both work fine. Checked all the fuses, all are ok. Have checked the grounds and those are ok also. Of course I have checked the bulbs as well and those are good too.

Not sure if it has anything to do with the problem at all, but the dashboard dimmer no longer works either, which I'm assuming is the rheostat.

Any ideas?
