Technical “Check Parking Lights”

[Forza500]

UPDATE: I decided to use my breakdown Home Start with RAC. Patrol came and changed the side/brake bulbs for new ones and magically rear lights work again and ‘check parking lights’ message has gone and triangle of doom has disappeared. Let’s hope the fix sticks!!

ANOTHER UPDATE: My daughter drove the car for the first time last night. She got to the end of our road and multiple warning lights came on Hill Holder unavailable, ESP, Brake monitoring, Tyre Pressure monitoring...although she said the car was driving fine (no limp mode). She was understandably freaked out So she turned around and came straight back home.
This morning I got into the car to make a note of all the warning lights as she said there were too many to remember and...nothing! Everything was fine. I took the car for a test drive expecting the warning lights to come on eventually but... it was all perfectly fine.

Obviously, I'm not sure I trust the car at the moment so I've called RAC out to have another look as I can't let my daughter drive a car that's not behaving itself! Anyone else experienced this after a tail light replacement? Could it just be a bunch of errors post bulb change that have now cleared themselves?

Engine earth strap?

FINAL UPDATE: RAC man came could only find one error with the car which was a CANBUS issue. He cleared it and it has been perfect since then driven every day with no issues. No warnings, all lights working.
Hope this helps with anyone who searches the forum in the future who has this problem.
Key takeaways: check all your bulbs are working, just change them all if they've been in the car for a while (ten years in my case), it's worth it and make sure the wattages match on pairs of bulbs.
