LEDs have very little load and the mechanical blinkers require a load to function.
There are LED compatible blinkers they have a ground wire that allows them to function .

I'm not that sharp on electrical, could you explain what I need to do? do I need different bulbs or something to create a load?

Because your system wasn't designed to use LEDs. Aside from most LEDs being polarized (will work when plugged in in one direction, but won't when plugged in the other way) the flasher unit won't work when there's not enough of a load on it. Like Dana67Dart said, you'll need an LED compatible flasher unit. Get one for your 4 way flashers if you are equipped with them, too.
Well you need to either replace the led bulbs with incondescent or you need to replace the blinker and flasher units with LED compatible units.
Standard (incondescent) flasher / blinker, note the guts have a contact points inside.
Led compatible flasher / blinker, note the guts have a circuit board inside and the lead for a dedicated ground. No mechanical contacts.
Don't be fooled into adding resisters to the circuits for the blinkers to work.
The entire reason I assume you added LEDs was to lighten the load on the wiring. By adding resisters you just increase the load on the wires till the stock units work and that defiets the purpose of the LEDs
thank you for the help, this old man just doesn't have it when it comes to electrical stuff. I will try and find where the flasher/blinker is plugged in and see about getting a replacement one for LED,s I replaced the lights for better visibility.
No I can not, I prefer incondescent
A LED works in only polarity. That means if you invert the LED it will have terminals in correct polarity. LED means "light emitting DIODE. A diode has a + terminal and a - one.

^^That is true, but only things like the cartridge dome lamps and reversible twist in dash lamp sockets can be reversed. Any bayonet bulb will automatically go in correctly, unless the socket or bulb is wired wrong.
Some LEDs have 2 bulbs in them, one in each polarity. That way they work regardless of which way they are plugged in.
FYI higher end led Christmas lights do the same, that way as the AC voltage goes negative one led goes out and the other goes on.
Otherwise they would have a 60 cycle flicker, or need a rectifier or capacitors etc!

I put LEDs in my taillights (where I wanted the extra brightness) and left the front turn signals with standard bulbs. My turn signals still worked.
The turn signal LED bulbs can’t be installed the wrong way If they have metal sockets That are the ground leg.

Working on my custom car parts again!
just get a electronic turn signal flasher . one that doesn't require a "load " on it to work.
Do you have a part # or location where I can obtain the flashers? Thanks in advance
