LED spotlight question

[Marc1980]

Hello. I am in the process of redecorating our bathroom. I ordered some GU10 led spotlights which came with the bulb socket and wiring. For some reason they do not work. They are replacing MR16 bulbs. I've attached photos showing the cable coming out of the ceiling, the old MR16 bulb and the new GU10 bulb.
Any ideas why the led GU10 bulbs don't work? Is it because the GU10's are led?
Any help appreciated.
Many thanks
Marc

The MR16 bulbs are most likely 12 volts, supplied by a transformer above the ceiling.
GU10 bulbs are 230 volts. You might need to get some help removing the transformers.
