Testing 3157 bulbs

I just ordered some LED 3157 bulbs for my tails, but they don't seem to be working in or out of the car. I tested it by directly connecting a 12V power supply to it, and it still doesn't seem to light up. I followed this diagram:

Does it require a special current or something, cause I can't seem to understand why it wont work. Payed 20 for them, dont want it to be a complete waste

thanks

LEDs are polar. if they don't light up in one position, chances are you only need to turn the bulb around in the socket.

Nvm, figured out that he didnt actually give me a 12V.. more like 24V, tard
