Question: do they have lights on center court at wimbledon

Answer: Yes, The first full match to be played with the roof closed was a men's singles fourth round match between British player Andy Murray and Switzerland's Stanislas Wawrinka. Play on Centre Court had never gone past 9.17 pm, but with the roof closed and the floodlights on, the match could be completed after dark -- at 10.38 pm. Merton Council's environmental chief David Simpson said after Murray's late-night win that late-night tennis would not cause any problems. However, when the record late finish was surpassed in 2010 during a match between Novak Djokovic and Olivier Rochus which ran until 10.58 pm it was reported that Merton council had imposed a curfew of 11 pm BST on Centre Court. This was then exceeded on Saturday 30 June 2012, when Andy Murray beat Marcos Baghdatis in their 3rd round match, which was completed at 11.02pm, in spite of the 11.00pm ruling.
