We had a couple of flickering LED lights, I pulled one out and it had two dead and one flickering of the 9 LEDs, put it back as I had no spare. Ordered some that arrived today. Fitted and what a change warm light instead of the harsh light of the original 14 year old bulbs, no flickering or blinking. Dead easy upgrade for £3 for 10 bulbs, got a load of spares for the future.
