Coast to Coast lighting with warning light

[pooler]

Good Morning everybody

My V2 Hybrid is parked overnight on charge, I noticed last night that the rear coast to coast lights came on for approx 30 seconds, this happened several times during the night.
The dashboard was displaying a yellow triangle.

Does anybody know what is happening?

Thanks for any help.
