I discovered a dead LED, in the light of a customer's model, last night..
Unfortunately, the LED is well and truly glued into the White-metal lamp, with epoxy.

I have cut the glue off flush across the back of the lamp, and will have to (very) carefully drill the remains of the LED out..
How I wish the drill-press was functional!
Well someone was smiling down on me:

The lens was slightly proud of the housing, so I decided to give it a squeeze with the pliers, and noticed a crack appear between the glue and housing...
Carefully supported at the back, and a couple of short, sharp shocks on the end of a piece of rod, and out it came.

I might need to put the kettle on, and celebrate with a brew!
