Technician A says test lights are great for quick tests on non-computerized circuits. Technician B says you can use a test light to check SRS circuits and computer circuits. Who is correct?

that technician A is right

Explanation:

The test lights are generally small bulbs that are turned on by the voltage and current flowing through the circuit in analog circuits, these two values are high and can light the bulb. In digital circuits the current is very small in the order of milliamps, so there is not enough power to turn on these lights.

From the above it is seen that technician A is right
