This Coast to Coast Interior Dome Light with on/off rocker switch slots straight into caravan and RV cabins that need simple 12V lighting you can flick at the fitting. The compact oval body sits neatly on a ceiling panel or cupboard side about 1.8–2.1 m off the floor, giving handy light for entrances, bunks or kitchen benches without hanging into head space. The silver finish looks at home next to standard RV fittings and trims.

The clear plastic dome lens spreads the lamp output over roughly 0.5–1.5 m, so one light covers a small area without wasting power from the main 12V system. The rocker switch is built into the housing, so there is no need for a separate wall switch or extra wiring run over more than 1–2 m. Straightforward surface mounting makes it a smart buy for tidy cabin lighting upgrades.

Q: Can this dome light be used as the main interior light in a small caravan?

Yes, it can act as a main light in a very small area. In a compact caravan or a single bunk space, one dome light can give enough cabin light for basic tasks. Larger vans usually run several similar fittings spaced along the ceiling. To brighten a full-size interior, plan multiple lights on the same 12V circuit.

Q: Does the on/off rocker switch mean I still need a separate wall switch?

No, the built-in rocker switch lets you control the light directly. Power runs from your 12V circuit into the fitting, and the switch breaks the circuit at the lamp. This helps when you want one area switched while others stay off. It also keeps wiring simpler in refits or small campers.

Q: Is this light suitable for mounting on either walls or ceilings inside an RV?

Yes, it suits both wall and ceiling mounting inside the cabin. The low-profile dome shape sits close to the surface so it will not stick far into walkways. Many people mount it above doors or along cupboard sides. Just make sure the backing panel is strong enough to hold the screws.

Q: Can I replace the existing lamp or light source in this fitting later on?

Yes, the clear dome lens is designed to be removed so you can access the lamp. This means you can change a worn bulb or swap to a compatible 12V option if needed. Always match the replacement to the original wattage and type. Using a correct lamp helps avoid overheating and extends the life of the fitting.

Suitable for use as an interior dome light in caravans and RVs where a 12V internal light is required and surface mounting is available. Install in a location with access to the vehicle’s 12V interior lighting circuit and adequate clearance behind the mounting surface for wiring. Use with compatible 12V light source and wiring sized to the existing circuit and switching load.
