Do Neon Signs Need A Transformer Or Can They Be Hardwired?

Neon signs need a transformer in order to step up the voltage from standard household levels to the higher voltage required to ionize the gas in the glass tubes. There are some signs that can be directly hardwired into a building’s electrical system, but this requires specialist wiring and expertise.

With hardwiring, you eliminate the need for a visible transformer. But it makes both the installation and maintenance more complex, so you will need to consult with a qualified electrician to determine whether it is feasible and safe.

Electrical codes and safety standards will play a big role in the decision.

Are Neon Signs Hardwired Or Do They Need A Plug?

Neon signs usually come with a plug, but they can actually be hardwired or equipped with a plug, and there are pros and cons to each.

Hardwiring:

  • Provides a cleaner look with no visible cords.
  • Requires professional installation and a dedicated electrical connection.

Plugs:

  • Offer easier installation and portability.
  • May be harder to achieve a neat, seamless installation.


Neon signs with plugs may be the better choice for temporary displays or situations where you need to move the sign frequently. But businesses with fixed signage often opt for hardwiring to create a permanent, streamlined appearance. Ultimately, the neon light wiring choice is down to you, depending on factors like aesthetics, convenience, and your intended use.
