If the question is, can I wire a switch to an existing light fixture (and I must assume that it's something like a pull-chain light fixture), the answer is yes.
If the question is, "how do I wire a switch to an existing light fixture that has no external switch", the answer is, "in series".
The attached web site gives simple instructions on how to wire a basic light switch to an existing light.

How do you add another porch light to an existing switch?
Piggyback off the box for the existing light. Run a wire from the existing junction box to a new junction box (which is placed wherever you want the new fixture). Then, in the existing box, connect the wire coming from the switch, the wire for the existing fixture, and the wire for the new fixture together using wire nuts. Wire up the new fixture, and presto, you have two fixtures on a switch where there was only one before.
How do you wire a 220 volts light?
The light is wired the same as any voltage fixture. Bring the source voltage to the fixture and connect it to the two fixture wires. If you want to control the off-on of the fixture take the source voltage to a switch first and then out of the switch to the light fixture.
How do you connect multiple lights to one switch starting at the light?
You put switch in series with the black supply wire and the black wire to the first light. Then connect black wire of first light to black wire of second light, black wire of second light to third light and so forth. Do the same with the white wires and ground wires.
How do you wire an additional light to another light with a switch?
In the wall switch box you should have a white and black pair from your source of power (120 volts). The other pair of black and white wires from the wall box should be going to the light fixture junction box. With the power off, connect the two white wires together with a wire nut. Connect the two bare copper ground wires together making sure that at least one of the ground wires goes under the green screw in the switch junction box. Turn the switch to the off position, no little indicator bump showing on the switch toggle lever. Now take the black incoming hot wire and put it under the top screw on the switch. Hot wires always go to the top of switches. Now put the black wire that is going to the light fixture under the bottom screw. Tighten both. Install the switch into the wall box with the switch handle in the down position. All switches when installed must be off in the down position. Install the switch plate cover.
Do you need a separate switch for a sensor light if I am connecting it from an existing light outside?
If you are taking the power from the existing light outside you have to be aware that when that outside light is switched off then the sensor light will not work. Your best choice should be power the sensor light from an un-switched source. This could be an existing receptacle outlet in a nearby location. Check your sensor configuration to see if the device has the function to be locked on and off by interrupting the voltage supply to it. If it does then a switch in its circuit is mandatory to make this function work. If this function is not included in the device then just connect it as the instructions explain and the fixture will come on when it senses movement and go off after a timed interval.

How can I wire a light switch to a light?
To wire a light switch to a light, you will need to connect the switch to the power source and the light fixture. Turn off the power, remove the cover plate, and disconnect the existing switch. Connect the wires from the switch to the corresponding wires in the wall and the light fixture. Secure the connections with wire nuts and screw the switch back into place. Turn the power back on and test the switch to ensure it is working properly.
How can I connect a wire switch to a light fixture?
To connect a wire switch to a light fixture, first turn off the power to the circuit. Then, connect the black wire from the switch to the black wire from the light fixture using a wire connector. Next, connect the white wires together and the ground wires together. Finally, secure all connections with electrical tape and mount the switch and light fixture as needed.
How do you connect an ON-OFF switch to control the light?
To control a light with a switch, the switch has to be connected in series with the light fixture.
How do you wire a switch to a light?
To wire a switch to a light, you connect the hot wire from the power source to one terminal on the switch, then connect another wire from the other terminal of the switch to the hot terminal on the light fixture. Finally, connect the neutral wires from the power source and the light fixture together.
How do you wire a switch to a light fixture?
To wire a switch to a light fixture, you will need to connect the hot wire from the power source to one terminal on the switch, then connect another wire from the other terminal on the switch to the hot terminal on the light fixture. Finally, connect the neutral wires from the power source and the light fixture together. Make sure to turn off the power before starting and follow all safety precautions.
How to wire a 3-way switch for controlling a light fixture?
To wire a 3-way switch for controlling a light fixture, you will need to connect the wires from the power source to the common terminal of the first switch. Then, connect the traveler wires between the two switches. Finally, connect the wire from the light fixture to the common terminal of the second switch. This setup allows you to control the light fixture from two different switches.
How can I add a light switch to an existing circuit?
To add a light switch to an existing circuit, you will need to first turn off the power to the circuit at the breaker box. Then, identify the hot wire in the circuit and connect it to one terminal of the switch. Connect the other terminal of the switch to the light fixture. Finally, connect the neutral wires together. Make sure to follow all safety precautions and consult a professional if needed.
How do you properly wire a switch to a light fixture?
To properly wire a switch to a light fixture, you need to connect the hot wire from the power source to one terminal on the switch, then connect another wire from the other terminal of the switch to the hot terminal on the light fixture. Finally, connect the neutral wires from the power source and the light fixture together. Make sure to turn off the power before starting and follow all safety precautions.

Finally, connect the neutral wires from the power source and the light fixture together. Make sure to follow all safety precautions and consult a professional if you are unsure.
How can I properly wire two switches to control a single light fixture?
To properly wire two switches to control a single light fixture, you will need to use a three-way switch setup. Connect the power source to the common terminal of the first switch, then connect the traveler wires to the corresponding terminals on both switches. Finally, connect the light fixture to the common terminal of the second switch. This setup allows either switch to control the light fixture independently.
