OK... this is hindsight, but there's always something to learn from the misfortune of others.
#1: If you can't see, STOP. Don't plow on, swinging the nose to and fro trying to sniff out a dark taxiway. #2: If the taxi light isn't cutting it, turn those big, beautiful landing lights back on. #3: Taxiways are usually lit after dark. If yours isn't, refer to #1, and ask ground control why not. Doesn't matter how familiar you are with the airport.
It's so easy after the fact, isn't it
