There have been cases of bad connections and wiring corrosion underneath the PDC (power distribution center-underhood fuse/relay box) because of its proximity to the battery. Check and clean connections starting at the battery terminals. Then remove the battery and flip the PDC upside-down the check the connectors there. Wires that appear lumpy or kinked may have internal copper breakage and corrosion. A gentle pull will find the wires that are broken inside as they will stretch (they shouldn't).
The clicking was probably the left and right headlamp and parking lamp relays. The relays themselves are probably not the problem.
This could be a safety issue. You may want to call your dealer if you can't find anything. It isn't fixed and will probably happen again.
