Low beams suddenly cut out. Since then, low beams are ok when car is cold (in morning or after sitting for several hours) but then cut out again at random time after car warms up, and stay off until next time car is cold. High beams & fog lights work fine, all other lighting and functions work fine. Suspect failed connection at punch-down board inside fuse box for circuit that supplies power to low-beam relay, requiring fuse box replacement, as has been diagnosed with several other reported identical incidents in C6 model Corvettes (first introduced in 2005) that I discovered during online research. Dealer will diagnose during emergency appointment in 2 days. Could cause serious accident if lights suddenly cut out while driving at night on unlit road.
