Lights are not working on the speedo or tach needles, how tough is this to replace myself?

Thanx its an ES300, 1994

 

Some one must know if you can replace the lights seperately, dealer wants $678.00 to replace the entire instrument cluster.

Help!

 

Unfortunately, that is the only option available over the counter. I'm sure something could be figured out if you did some exploring on your own, but no one has decided to seek out an alternative to replacing the entire cluster in the 10 years of making these cars.
