I noticed the other night that part of my speedometer and tach have partially gone dim. I suspect this means a bulb has gone out. Has anyone else encountered this before 70k miles? My next question is option #1, use my 80k warranty (will this be covered and is it worth the $100 deductable?); #2: is it possible to swap the cluster out with that of the SLK-320 cluster?; or #3: disassemble the dash and change the bulbs for LED's. Anyone else do/encounter any of these?

TIA!
