Obeaming 12V PWM Light Dimmer Switch for RVs & Boats — Black 7/8" Mount, 6A, Blue Backlight

Obeaming's 12V high-side PWM dimmer is a recessed push-button switch that provides smooth, flicker-free dimming for LED, halogen and incandescent DC 12V lighting with a 7/8" mounting hole and 6A rating. This compact black-alloy dimmer combines a tactile push button with stepless pulse-width modulation control so you can switch lights on/off with a quick press and finely adjust brightness by holding the button. It includes a blue backlight for low-light visibility, a memory function to restore the last brightness and a recessed housing for a neat panel finish—designed for RVs, boats, trucks, cabinets and other 12V systems.

How does the dimmer deliver smooth, flicker-free light?

The switch uses high-side PWM (pulse-width modulation) to vary duty cycle without altering voltage, producing linear dimming from about 3% up to 100% brightness. PWM avoids audible hum and visible flicker common with simpler dimming methods, making it stable across different lamp types.

• 3%–100% stepless dimming for fine control
• High-side design compatible with many 12V loads
• Flicker-free output, no hum or buzz

What controls and conveniences does the switch provide?

Operation is straightforward: a short press toggles power on or off, while holding the button ramps brightness up or down. The unit remembers the last on/off state and brightness level, so lights return to the same setting after power cycles.

• Short press = on/off; press-and-hold = smooth brightness adjustment
• Built-in brightness memory restores previous setting on next use
• Blue backlight helps locate the control in darkness

Which lights and systems is this dimmer suitable for?

The dimmer supports a range of DC12V loads including non-regulated LEDs, halogen and incandescent fixtures, plus LED strip lights. Rated for a maximum continuous current of 6 amps, it's intended for small lighting circuits in mobile and fixed installations.

• Rated max 6A for single-circuit loads up to typical strip/light fixtures
• Compatible with LED strips, halogen, incandescent and similar 12V lights
• Not for high-voltage AC mains; intended for DC 12V applications only

How do I mount and fit the dimmer into my panel or vehicle?

The body is designed for recessed installation into a 7/8" (22 mm) hole, offering a clean, low-profile look ideal for control panels, under-cabinet installations and dash applications. The all-aluminum shell gives a durable finish that resists corrosion in mobile environments.

• Drill a 7/8" (22 mm) mounting hole for recessed installation
• All-aluminum shell in black provides durability and a neat aesthetic
• Compact footprint fits custom panels in RVs, boats, trucks and cabinets

Who is this for? This Obeaming dimmer is aimed at DIYers, marine and RV owners, vehicle customizers and anyone upgrading 12V lighting who wants precise, quiet dimming with a tidy recessed switch. It's a practical choice when you need a small, reliable control that remembers settings, is easy to operate in the dark, and fits into existing 22 mm switch panels or custom mounting points without adding bulk.
