Interior Lighting

What types of RV interior lights does this collection include?

The Interior Lighting collection covers 12V LED dome lights, ceiling fixtures, reading lights, and replacement bulbs for camper and motorhome interiors. Most options run on standard RV 12-volt DC power, so they wire directly into existing circuits without an inverter. For broader 12V component needs, see our RV electronics collection.

Are LED interior lights more efficient than incandescent RV bulbs?

Yes. LED interior lights draw roughly 0.2 to 0.5 amps per fixture compared to 1.5 to 2 amps for equivalent incandescent bulbs, which matters when you are running off house batteries. They also produce less heat and typically last 25,000 to 50,000 hours, so they hold up well to vibration and frequent on-off cycling in an RV.

How do I know which RV dome light will fit my existing cutout?

Measure the existing fixture's mounting footprint and the ceiling cutout before ordering. Most RV dome lights use a standard rectangular or round mounting pattern, but lens dimensions vary by brand. Check the product specs for length, width, and depth, and confirm the voltage (12V DC) matches your system.

Can I install RV interior lights myself?

Most interior light replacements are a straightforward DIY job: disconnect 12V power at the battery or fuse, remove the existing fixture, transfer the positive and negative wires to the new unit, and mount. A multimeter helps confirm polarity before final connection. If you are also upgrading shore power connections, our RV plug adapters collection covers the exterior side.

Do these lights work with both shore power and battery?

Yes. RV interior lights run on the 12V DC house system, which is powered by your batteries when boondocking and by the converter when plugged into shore power. The fixtures themselves do not care which source is charging the batteries, so they operate the same way in both scenarios.

Does United RV Parts offer free shipping on interior lighting orders?
