To replace a strobe light bulb, first, ensure the power is turned off and the unit is unplugged to avoid electrical shock. Allow the bulb to cool if it has been in use.
Next, remove the cover or casing of the strobe light, which may require a screwdriver. Carefully unscrew or release the old bulb from its socket. Insert the new strobe bulb, ensuring it is securely in place. Reattach the cover or casing and plug the unit back in. Finally, test the strobe light to ensure the new bulb is functioning properly.
