I recently bought some #44-4 leds bulbs from cointaker and i was getting ready to install in one of my machines.I put the led in the socket and as soon as i twisted the led to secure in the socket the top of the led CAME OFF!! at first i thought it was a bad led but come to find out all the 4leds were doing the same thing.What a waste!!! The best leds are the ultra brights they cost more but they awesome and worth it.Anyone else had the same problem?
