Hi Win,
Take my word bright flickering lights have always triggered seizures for me. I saw my epileptologist and he did a special e.e.g on me flashing different color strobe lights one at a time and he found that bright white, amber, and florescent green were the 3 main colors that would trigger seizures for me. He told me that when this happens it means that a person is photosensitive. If this happens to you again turn your head away and look at a dark color this has helped me a lot from having any seizures from the bright lights. I wish you the best of luck and May God Bless You!
