Partial successful fix of the 7W nightlight

Remember that 7w nightlight that I got from the car boot sale alongside with the Lyvia 7w and the other 2 which were shaped like computer mice?

I managed to drill the seized screw out and pull out the loose 7w bulb and found a spare 7w bulb

This was successful for 15 seconds until the bulb flickered and then after a faint grey white flash it was burnt out
