Hello! I've never previously owned a Volvo but just purchased one from my neighbor and got it completely serviced. It runs great! I just have a silly question as I have been having problems recently with it starting. 2 weeks ago, when I started the car it made a clicking sound. I automatically assumed it was the battery, I got it jumped and got the battery checked out. It was all good and didnt need to be replaced. A couple weeks later, the same clicking happened but I waited and tried again and it started. Same thing just happened again today. (no jump needed last two times).

I'm worried I am not turning off the lights??? I feel like they stay on but I'm not familiar with the electrical of a Volvo. I have attached a photo.

Can someone help? Thanks a bunch!
