Ah, I'm surprised you noticed them - they are the teeny weeny floodlightettes at what I shall continue to refer to as the County Ground, home of Gloucestershire County Cricket Club (I think the official name, this year, is the Poundland Woopsie Bargain Arena or something).
I've always known it as Nevil Road, so as not to confuse it with the County Ground in Taunton, home to the superior Somerset CCC.
Although Somerset's ground has a silly sponsorship name too. Tommy Cooper Associates County Ground I think.
