Set the details for your vehicle and they point to all the choices for your applications.
EDIT: My truck came with LED parking lights and turn signals front and rear, from the factory. Even interior lighting is LED.

I'm still on the fence about changing from halogen to LED headlamps as it is illegal and I have to get inspected annually.
