FBULWSEC 12V Toggle Dimmer Switch for RVs and Boats — Compact 60W 12V DC Panel-Mount

FBULWSEC 12V toggle dimmer is a compact, retro-styled switch that adjusts brightness for 12V dimmable LED, halogen and incandescent lighting in RVs, boats, trucks and other vehicles.

This low-voltage dimmer blends classic toggle styling with practical performance for mobile and small-space power systems. It accepts 12 volt DC input, supports typical dimmable lighting loads, and is sized to fit common cutouts in RV panels and dashboards. The housing is built from a durable plastic composite and mounts with hidden screws for a clean appearance. Whether you want softer cabin lighting for evening drives or to reduce battery drain on shore power, this switch offers a simple manual control solution.

How much load can this dimmer handle?

The switch is designed for small 12V circuits and supports up to 60 watts of incandescent, halogen or LED lighting at nominal 12V (about 4.2 amps). It also carries a higher surge capacity up to 10 amps for short periods, but continuous loads above the 60W guideline are not recommended.

• Normal continuous rating: dims up to 60W (≈4.2A) at 12V DC
• Maximum surge/peak rating: 10A (not for sustained use above 60W)
• Compatible with dimmable LED drivers, halogen and incandescent lamps
• Reduces heat and lowers standby power compared with non-dimmable load

What are the physical dimensions and cutout requirements?

The unit is compact and fits into tight panels commonly found in motorhome and marine interiors. It’s built to align with standard small switch openings so you can retrofit an existing location or plan a clean new installation.

• Overall size: 1-7/8" wide × 2-7/8" tall × 3/8" deep
• Minimum panel cutout: 1-1/2" tall × 1-1/8" wide
• Hidden screw mounting for a neat, finished look
• Rounded edges for safer handling and better fit against surfaces

Which vehicles and fixtures is it compatible with?

This toggle dimmer suits a wide range of 12V systems found in RVs, camper conversions, trucks, boats and specialty trailers. It is appropriate for lighting circuits and many auxiliary devices listed as dimmable or within the switch’s power limits.

• Typical applications: cabin lights, accent strips, dome lights, and reading lamps
• Also used for pumps, fans, vents and small accessories where dim control is acceptable
• Works with dimming-capable LED drivers and resistive halogen/incandescent loads
• Common in RVs, travel trailers, buses, horse trailers, haulers and marine vessels

How easy is installation and what materials are used?

Installation is straightforward for anyone comfortable with basic 12V wiring and panel cutting. The switch body is made from a durable plastic composite designed to resist wear while keeping weight low for vehicle use.

• Simple two- or three-wire hookup depending on wiring scheme
• Durable plastic composite housing with rounded edges for safety
• Hidden screws provide a tidy finished appearance after installation
