Car Strobe Lights

Hello, I am working on making strobe lights for my car. So far I have made the strobe lights, which are 12 volt led strips. I am wanting to use my Arduino Uno to make them flash. I have the board programed already, but I cannot figure out how to power my lights with the board. I can get the lights to illuminate if I power them through the Vin pin, but I cannot power them through the digital pins, because they don’t put out 12 volts. Can somebody help me figure out how to power my lights please? I want to keep it as simple as possible. Thank you very much in advance! I’m willing to give out any additional information needed.

Something like this: https://learn.adafruit.com/rgb-led-strips/usage. I looked for an equivalent tutorial on Sparkfun’s site, but didn’t see one.

That is perfect! Thank you so much!!
