Auxbeam 4 Gang Slim RGB Switch Panel AS-R40 - Auto-Dimming 3 Modes

In this review the Auxbeam 4 Gang Slim RGB Switch Panel AS-R40 stands out as a practical, well-built control solution for 12-24V vehicles that need compact, configurable switching. The single biggest reason to consider it is its combination of flexible RGB backlight customization with three distinct lighting modes and a memory function, which together make it useful for drivers who want both convenience and visual clarity on dash-mounted controls. Installation is straightforward and the unit feels robust for daily use.

Key Features

• Auto-dimming backlight: The panel automatically brightens or dims to match ambient lighting, reducing eye strain while driving day or night.
• Three lighting modes: TOGGLE, MOMENTARY and PULSED modes let the same panel operate steady accessories, act as a press-and-hold control, or create a strobe output for auxiliary lights.
• Backlight off option: A MODE button lets users quickly deactivate the backlight when a dark cabin is preferred or to avoid distraction.
• Memory function: The ON/OFF button restores prior light settings after power cycles for consistent behavior without repeated setup.
• Safety features: The included control box has solid-state relays and a resettable circuit breaker to protect against reverse polarity, overcurrent and overheating.
• Flexible mounting: Two mounting brackets and double-sided tape are included so the slim panel can be dashboard- or console-mounted where it fits best.

Who It's For

This switch panel is aimed at owners of trucks, off-road vehicles, boats and other 12-24V platforms who need a compact, multi-circuit control center with visual feedback and configurable behavior. It is particularly useful for people installing auxiliary lighting, horns, or accessories who want toggle, momentary and pulsed options in one device.

Those who need wireless app control or integrated Bluetooth features should look elsewhere, since the AS-R40 does not support app control. Also, users who require dozens of dedicated switches or OEM-specific integration may prefer a larger, vehicle-specific solution.

Pros & Cons

Pros

• Versatile lighting modes provide real utility for different accessories and emergency uses.
