Fireworks used to be associated with Bonfire Night, 5th November, but nowadays they are employed for many occasions, not least of which (for Ricardians) was the week-long celebration of Richard’s reinterment at Leicester Cathedral. The reinterment was on 26 March 2015, and ended with a spectacular fireworks display around the cathedral.
This link is to a collection of 80 photographs of many memorable fireworks displays in Leicester. Richard’s reinterment display features at numbers 11-13, 35 and 74. If there are more, I didn’t find them.
