When I took them out of the lamp, they more or less fell apart. The metal end caps were very slack and were used to nip
onto the voltage resistors on each end. The body of the bulb is a plastic tube, not glass. Overall, a pretty cheap affair.

Worse still, using a 12 volt supply (with correct polarity), they didn't work when I reassembled them. They'd blown/fused/popped
or whatever LEDs do. They went in the bin. I found my trusty old festoons in the desk drawer (I never chuck anything away unless it's useless) and decided my LED lighting experience was now complete (long story).

Hmmm - all the LED's wired in parallel, but with one resistor in series, by the looks of it....
That basically means if one LED fails, the rest will get over voltage causing them to fail too. The more fail, the faster the rest will die too.
