Hi,
Visually all external lamps/bulbs are working perfectly fine except 2 reverse white lights. Bulbs are fine but there is no 12v in left and right wire holders. image are attached for a closer look.

Without touching anything else, when I start the engine only then I receive the message "Lamp Defective Check Lamps!".
Is this message appearing due to reverse light wiring issue? if yes then my point is that unless I am not putting the car in reverse gear it should not throw this message.

Kindly help me with this error message.

Thanks!
THG
