2007 CC - How to add turn signals

[ghc]

I am a proud new owner of a 2007 Club Car Precedent. In order to use the cart on the course that I belong to it has to be street legal. The cart already has headlights, taillights and a horn (horn button mounted on steering column). I need to add turn signals and brake lights. I am not sure what parts I need to buy. I don't know if the current setup is a factory set up or after market. How can I tell in order that I acquire the correct parts? I believe the local cart shop wants about $400 to do the job. I am hoping that I can do modifications myself.
