A stock bulb and stock tube is plenty bright enough, no real need to make them any brighter... plus you'll melt the plastic lens since more heat is trapped in the tube.

I understand that sometimes its fun and good to improve certain stock items, but this isn't an issue that needs improvement over clean stock parts. Clean/new stock is a good enough upgrade from 50 year old lenses and bulbs, don't just assume that stock isn't bright enough if you haven't already installed new bulbs and clean/fresh lenses.
