FBULWSEC 12V RV LED Dimmer Switch Toggle - High-Side 60W Compact Panel Mount for RVs, Boats, Trucks

FBULWSEC 12 Volt RV LED Dimmer is a compact toggle-style high-side dimmer that controls up to 60W of LED, halogen, or incandescent lighting for vehicles and small DC systems.

This toggle dimmer switch is designed for tight quarters where reliable, adjustable 12V lighting control is needed—think RVs, boats, trucks, trailers and conversion projects. It pairs a retro, easy-to-operate toggle with modern dimming electronics so you can reduce brightness, battery load and heat without changing fixtures. The switch is made from a durable plastic composite and is sized to fit common panel cutouts, making it straightforward to mount and wire into existing DC lighting circuits.

How does this dimmer work with 12V LED, halogen, and incandescent lights?

The dimmer is a high-side DC control that varies supply to the lamp circuits, allowing smooth brightness adjustment across compatible bulbs. It supports a combined load up to 60 watts (about 4.2 amps) so it can handle several fixtures or a length of LED strip within that limit.

• Supports LED, halogen and incandescent loads up to 60W total.
• High-side switching suitable for most 12V vehicle lighting circuits.
• Toggle action provides tactile on/off and dimming control.
• Reduces heat and energy draw versus running lights at full power.

How simple is the installation and what dimensions matter?

Installation is intended to be straightforward for anyone familiar with basic 12V wiring and panel cutouts. The unit’s compact footprint and standard hole spacing let it mount cleanly in many RV and marine panels.

• Overall dimensions: 3" x 2-7/8" x 1-1/2" for panel depth planning.
• Recommended panel cutout: 2-1/4" x 1-3/4" x 3/4" to fit the faceplate and toggle.
• Mounting hole spacing: 1-1/4" horizontal by 1-7/8" vertical.
• Wiring: standard DC positive/negative terminals; follow vehicle wiring best practices.

Will this dimmer fit in tight spaces and various vehicles?

The compact design is purposely made for crowded control panels and small compartments. It’s commonly used in RVs, travel trailers, buses, boats, horse trailers and conversion vans where 12V power is standard.

• Low-profile body suits shallow panel depths and cramped mounting locations.
• Rounded edges and a readable toggle enhance the finished look in cabins and consoles.
• Works with a wide range of 12V systems—ideal for retrofit projects.
• Not intended for high-current loads beyond the specified 4.2A limit.

What materials and durability features should I expect?

The switch housing and toggle are molded from a robust plastic composite designed to resist impact and wear in mobile environments. The construction balances lightweight design with everyday durability for on-road and marine use.

• Durable plastic composite housing with rounded edges for comfort and appearance.
• Tactile toggle built for repeated operation in vehicle conditions.
• Electrical components sized for stable dimming under specified load.
• Customer support available for replacements or returns if the unit isn’t right.

Who this is for: Installers, DIY van-lifers, RV owners, boat and truck customizers, and anyone converting a vehicle to 12V lighting who needs a compact, easy-to-mount dimmer. Choose this FBULWSEC dimmer when you want a simple toggle control that reduces light output and battery drain without a complex retrofit. If your circuit requires more than 60W or advanced PWM compatibility with specific LED drivers, verify load and driver compatibility before purchase.
