Dash lights

Now I just remembered the question I had!
I took the new '66 Cuda out for an evening spin and noticed the dash lights behind the gauges are pretty darn dim. I'm thinking about pulling the cluster apart and cleaning any contacts for corosion and in the bulb slots as well. I was wondering if anyone knows of a brighter bulb I can use or if anyone has tried using LEDs in their dash? If not then stay tuned, I'll see if it works! Figured LEDs would use less juice anyways and should be brighter too.

Ideas?
