LED's will not illuminate unless connected the correct way round. Test the actual led on a battery, to make sure it works, then crimp the correct way round.

ive tried swapping the connections out but still no joy,i will test them on a battery see what happens theres a black and a red wire on the LED

Probably a stupid question, but did you buy 12v LED down lighters?

the old ones worked just that the glass was broken so i decided to switch them to LEDs,will check though all other lights still ok

LEDs generally operate between 1.2 and 3.6 volts. The units you have bought will have a built in DC-DC converter to drop the voltage from 12v to the voltage required by the LED. It's possible that these may have been damaged if you connected them reverse polarity, is there anything in the instructions to say whether they have reverse polarity protection?

It's also possible that they were faulty when you bought them, how many did you buy?

You could hook up one of the old lights to prove the supply is still there, if it is it would seem that the LEDs are dead.

Two tests,

Do you have voltage at the connecting wires?

Do the new LED bulbs work when wired directly to a battery?
