Putting LED 3157 replacement turn signals blew fuse why?

I just finished installing my hid conversion kit to my headlights and fog lights. I also wanted to place LED's in my parking and turn signals. When I put the 3157 led bulb in the turn signal it blew the fuse? I tried swapping fuses and they kept blowing? Anyone know why, or what causes this or how can I get them to work? thanks

 

If i remember right there is something that you have to have for the LED turn signals. My brother tried to do it and his did the same thing. I dont remember what it was called but i would just google search it lol.

 

You'll more then likely need a relay designed to run the low amperage LED turn signals. The draw so much less than with an incandescent bulb, you will run into issues with the standard OEM turn signal relay. Do a little research and you'll find out all the information you would need to know.

 

I think its resistors is what you have to have. I just looked it up and people had the same problems. Hope it all works out.
