1995 SL320 - Headlights
 

My defective lamp indicator has been lit since I purchased the car 3 weeks ago. Driving at night it seems the high beam on the passenger's side did not work. I never bothered until today after replacing the bulbs to actually look at the front to see what lamps were working.

The actual issue is that both high and low beam are working on the passenger's side, however, it is much dimmer than the driver's side. I tried the old bulb from the driver's side the was good, but the results are the same. The defective lamp indicator is no longer lit with the new bulb, just very dim. What should I look at?
