Sprucing up old lights

Of course my Dad's layout had some lights for illumination. That was 30 years ago, so everything was done with incandescent bulbs. The lights masts are not very detailed, but reasonable for inconspicuous locations. If only the bulbs weren't so huge!

After a failed experiment with a SMD LED, I replaced the original 16V AC bulbs with 12V DC grain of rice bulbs from MicroMark. That requires removing the shade, cutting out most of the bulb socket, and soldering in tight spaces. However, the effect is well worth it.

3 lights done. Two more to do.
