I had just gotten a package of LED coloured light and all of them work except one. strangely as soon as I unplug it ,it flashes for a second. what does this mean and how can I fix it?

  • What kind of power supply does it use? – wallyk Jul 11 '14 at 23:47
  • a 12volt MR16 plug and if this helps the plug prongs are a little slanted to the side – Nolan Jul 12 '14 at 0:01

Could be reversed polarity - and the power supply may put out an opposite voltage spike when shut off.
