Dashboard light help

Hey guys, while driving home from work tonight a light on my dashboard began flickering when I was turning into the freeway. It is the far right set of lights, the third light from the bottom (or top as I believe there are only 5 lights/slots there). Any ideas on what it is!?!

Not sure if it'll help but I have a 94 SL.

Thanks in advance.

refill your windshield washer fluid and it will go away
