Lighting in a Recreational Vehicle (RV) is crucial for both safety and creating a comfortable, home-like environment. Optimizing your RV's lighting system—from the energy source to the bulb type and placement—can drastically improve your travel experience and battery life.

I. Understanding RV Lighting Power

Most RV lighting operates on a 12-volt DC system, which is powered by your RV's house battery. Understanding this system is the first step toward efficiency.

A. Energy Conservation

When dry camping or boondocking, every watt counts. Switching to energy-efficient bulbs is the single most impactful upgrade for battery longevity.

• LED vs. Incandescent: LED bulbs consume up to 90% less power than traditional incandescent bulbs and last significantly longer. Incandescents draw a lot of current and generate excessive heat.
• Voltmeter Monitoring: Regularly monitor your battery's voltage to ensure it stays above a safe discharge level, typically 12.0 volts.

B. Types of RV Bulbs

Bulb Type	Energy Draw	Heat Output	Lifespan
LED	Very Low	Low	Long
Halogen	Moderate/High	High	Moderate
Fluorescent	Low	Moderate	Moderate

II. Optimizing Interior Lighting

Interior lighting should be functional, energy-efficient, and aesthetically pleasing. A well-lit RV makes a small space feel larger and more inviting.

A. Task Lighting

Focus on installing bright, targeted lighting in areas where detailed activities occur.

• Kitchen: Install under-cabinet strip lighting to illuminate countertops for cooking and food preparation.
• Bedside: Use directional reading lights with flexible necks for focused light that won't disturb a sleeping companion.
• Bathroom: Ensure vanity lighting provides clear, shadow-free illumination for grooming.

B. Ambient Lighting

This is the general lighting that fills the main living space and sets the mood.

• Dimmer Switches: Utilize dimmer switches on overhead ceiling lights to adjust brightness and conserve power when full illumination is not needed.
• Warm Color Temperature: Opt for LED bulbs with a "warm white" color temperature (around 2700K to 3000K) to create a cozy, relaxing atmosphere, as opposed to the harsh look of "cool white."

C. Decorative and Accent Lighting

Add soft accent lighting to enhance the RV's design.

• Puck Lights: Small, circular lights can be installed inside cabinets or above shelves to highlight decor.
• Rope Lighting: Flexible rope lighting can be tucked into ceiling coves or under slide-out fascias for a soft, indirect glow.

III. Exterior and Safety Lighting

Exterior lighting is essential for safety, security, and setting up camp after dark.

A. Utility and Security Lights

These lights are vital for tasks and deterring unwelcome visitors.

• Porch Light: Ensure your main entry door has a functioning, bright light. Consider a motion-sensor option for security.
• Storage Bay Lights: Install LEDs inside exterior storage bays to make accessing gear easy, especially after sunset.

B. Awning and Accent Lighting

Lighting under your awning creates a welcoming outdoor living space.

• LED Strip Lights: The most popular choice for awning lighting, these strips are durable and weather-resistant.
• Bug Lights: Use yellow-tinted bulbs in exterior fixtures to reduce the attraction of insects.
