* Parking Lights: These are usually activated by a knob or switch that's often located on the steering column, near the turn signal stalk. It will have a symbol that looks like a small headlight. Turning this on illuminates only the front and rear parking lights.
* Headlights: These are generally controlled by a switch, again often on the steering column near the turn signal stalk. It might have a symbol of a larger headlight. Turning this on illuminates both the headlights and the tail lights. On some models, there may be multiple headlight settings (low beam, high beam).
If you're looking for *additional* driving lights (like aftermarket fog lights or auxiliary lights), those would require a separate switch and wiring installation, as they weren't standard equipment. Check your owner's manual for more specific information related to your truck's lighting system.
