After a normal landing the flight crew took the precaution of requesting assistance because the lights guiding aircraft from the runway to the taxiway were unclear.
You missed the part about having taxied over lights prior.
IF the crew had doubts, seems to me they should have held position
prior to making contact with frangible lights, and
then asked for assistance.
That they did not, brought problems.
Perhaps a little retraining is in order.
