Flying saucer with red lights.

Me and my Mrs were sat watching the TV when my Mrs exclaimed 'What the f**k is that?' She pointed to our open window and a flying saucer a couple of hundred feet away flew past our house. It was Brilliantly illuminated by varying red glowing spheres. A central large one and two either side of it about half as big as the central one. Above and below it was a strip of much smaller red spheres. The body of the saucer looked black. At points the lights were so strong it was hard to see details but the lights were pulsing so that when it didn't shine so bright I was able to see the details I described. As my Mrs tried to capture it on her phone I went out onto our garden and waved at it with both arms in an attempt to get it to come back. Instead of moving further away it shut its lights off. I waited 5 minutes to see if I could see anymore, but no.
