While my friends were cleaning my car during the day, I removed the spare wheel from the trunk and saw these two sockets. I wonder what these are. friends with knowledge can help. they are already oxidized because they are not used. but I was still wondering what they were ... Meanwhile, my car is out of 2005 traffic. I did not pay much attention to the spare wheel when buying it, and I saw that the original spare wheel is still standing. production date is 2005. I am both glad and surprised that it has not been used until this time ....
