How can neon lights designed for lower voltages be used in higher voltages?

Neon lights designed for lower voltages can be effectively utilized in higher voltage applications through the use of resistors built into the socket. This approach regulates the voltage that reaches the neon bulb, ensuring that it operates within its designed voltage range despite being connected to a higher voltage source. The resistor acts as a form of voltage divider, dissipating excess voltage as heat. This not only protects the neon light from potential damage due to over-voltage conditions but also allows it to function safely and efficiently.

It's important to note that while other methods can influence how neon lights operate, they do not directly address the need to adapt low-voltage bulbs to higher-voltage systems in the same effective manner as using resistors. For example, increasing wire size might improve current carrying capacity but does not modify the voltage delivered to the neon light. Using a transformer could also be a solution, but it generally serves the opposite purpose by stepping voltage down rather than adapting a low-voltage light to higher voltages. Shielding with insulation does not impact the voltage levels but rather focuses on safety and preventing electrical contact. Thus, integrating resistors in the socket remains the most direct and practical method for this specific scenario.
