To test a light bulb with a voltmeter, set the voltmeter to measure AC voltage. Then, place the voltmeter probes on the metal contacts at the base of the light bulb. If the light bulb is working properly, the voltmeter should display a voltage reading. If there is no reading, the light bulb may be defective and needs to be replaced.
When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.
You can measure the voltage of a light bulb by using a multimeter set to the voltage setting. Simply touch the positive and negative probes of the multimeter to the base of the light bulb where it connects to the socket to measure the voltage across the bulb.
You can test if something is an insulator or conductor by connecting a circuit with a power source and a light bulb. If the material allows the light bulb to turn on, it is a conductor. If the light bulb does not turn on, it is an insulator.
A voltmeter connected across the broken (open) filament of a light bulb reads the full voltage of the power supply whether the bulb is in a series or parallel circuit. -- In a series circuit with other components in series with the bulb, this reading tells you that at least one of the components is open, possibly the filament. -- In a parallel circuit with other components in parallel with the bulb, or with the bulb connected directly to the power supply, this reading tells you nothing ... the voltmeter reads the full power supply voltage whether the bulb is open or good. The voltmeter isn't a very helpful measurement to identify an open filament. An ohmmeter, with the power to the circuit turned off, is much more helpful.
To test if a material is a conductor or insulator, you can set up a simple circuit with a battery, wires, and a light bulb. When the circuit is open (broken), no current flows and the light bulb does not light up, indicating an insulating material. When the circuit is closed (connected), current flows and the light bulb lights up, indicating a conducting material.

I have to suggest the light switch is bad. A simple voltmeter or test light may help you test voltages. I have to suggest the light switch is bad. A simple voltmeter or test light may help you test voltages.
Either touch the metal tab with a voltmeter/test light or take it out and look at it one at a time.Either touch the metal tab with a voltmeter/test light or take it out and look at it one at a time.
To test a light bulb, simply screw it into a working lamp or fixture and turn it on. If the light bulb illuminates, it is working properly. If it does not light up, try replacing it with a new bulb to confirm if the issue is with the bulb or the fixture.

the only way to test one is to put the bulb in the strobe housing and apply recommended power.
To install a light bulb into a light bulb receptacle, first make sure the power is turned off. Then, gently insert the base of the light bulb into the receptacle and twist it clockwise until it is securely in place. Finally, turn the power back on to test the light bulb.
A voltmeter
You could have a bad wire going to the socket. You can test the connection with a voltmeter. If you are unsure of where to connect the voltmeter try it on the good side first when someone is applying the brakes to see how to connect the meter. Then try the bad side and if you can't get a reading you have a wire or connection problem on the bad side. The taillight bulb has two filaments One is used for the normal tail light and the other filament is used when you step on the brake. When you step on the break both filaments are on at the same time to give the extra brightness. Take the bulb out and check the continuity of both filaments to make sure that they not burned out.
