What is the RV's Interior Lighting System

The RV's interior lighting system is often designed to be energy-efficient, utilizing LED bulbs and fixtures to minimize power consumption while providing adequate illumination for comfortable living conditions. The RV's lighting system is powered by a 12V DC or 120V AC electrical system, which consists of the following key components:

Power system

  • 12V DC system: The heart of the 12V DC system is the deep-cycle lead-acid batteries, typically two to four batteries wired in parallel. These batteries store electrical power to run the RV interior lights and other DC appliances when not connected to shore power or a generator.
  • 120V AC system: The 120V AC system in an RV functions similarly to the electrical system in a house. It typically involves a power cord that connects the RV to an external power source, such as shore power or a generator. Once connected, the power is distributed through a breaker panel inside the RV. 120V AC appliances, such as air conditioners and microwaves, can be directly connected to shore power or a generator through the breaker panel (If available). However, 12V DC lights inside the RV require the RV's power converter to transform the 120V AC power into 12V DC power before they can illuminate.

Generally speaking, it is more common for RVers to use 12V DC lighting systems inside their RVs because it is safer and reduces the risk of power short circuits and lightning strikes.


This device converts 120V AC power from shore power or a generator into 12V DC power to charge the batteries and power the DC circuits. It also acts as a battery charger when plugged into AC power.


These protect the lighting circuits from electrical overloads by disconnecting power if too much current flows through them.


The wiring connects the batteries, converter, and lighting fixtures/appliances into circuits. Proper wire sizing is important to handle the current loads.

Lighting Fixtures

These include interior lights (ceiling, reading, etc.), exterior lights (porch, awning, etc.), and other 12V DC light sources. LED lights are becoming increasingly common for their energy efficiency.


  • When connected to shore power or a generator, the converter/charger charges the batteries and powers the 12V DC circuits directly.
  • When dry camping without AC power, the batteries supply 12V DC power to run the lights and appliances until depleted.
  • Lighting circuits have individual fuses/breakers to prevent overloads from too many lights being on.
  • Dimming of lights occurs as the battery charge level drops, indicating a need to recharge the batteries.

Many RVs utilize a combination of both systems for their interior lighting. Understanding this will be instrumental when choosing the right type of RV interior light for each area.
