What this is A 3CH remotecontrol switch panel for RC car and truck model lighting that includes a breathing flash function. Material: metal and plastic. Designed as a replacement part for RC rock crawlers and other scale models. Key benefits — why you need it Centralized control: one 3channel panel lets you switch and combine multiple light circuits from a single remote, simplifying wiring and installation. Works with common LEDs: supports up to 12 pieces of 5mm LED lights, so you can drive headlights, roof lights, and auxiliary lamps without adding extra controllers. Improved realism and visibility: the breathing flash function adds a smooth pulsing effect for realistic running lights or attention signals while improving nighttime visibility. Durable construction: metal and plastic components provide a balance of strength and lightweight installation for model use. Main functions and performance 3channel switching: independently control three lighting circuits for flexible configurations (e.g., headlights, tail lights, auxiliary lights). Breathing flash function: a soft pulsing light mode for one or more channels to simulate running lights or strobestyle effects. LED support: compatible with up to 12 × 5mm LEDs, allowing multiple lights per channel as required by your build. Compatibility and fit Intended for use with RC cars, trucks, and rock crawlers as a replacement or upgrade lighting switch panel. Uses standard 5mm LED sizes; confirm LED type and wiring of your model before installation to ensure compatibility. Metal and plastic construction suitable for scale model mounting; verify mounting space and connector compatibility in your vehicle. Typical use scenarios 1. Night trail runs: a damaged switch panel on an RC rock crawler to restore control of headlights and auxiliary pods while adding a breathing flash mode for visibility on dark trails. 2. Scale show builds: Centralize and control multiple 5mm LEDs for realistic headlight and roofbar effects during indoor or display events. 3. Field and upgrades: Swap in this 3CH panel to upgrade an older model's lighting system, consolidate wiring, or add pulsing/attention lights for safety and realism. Installation notes and recommendations Confirm wiring polarity and channel assignments before powering up. The panel is designed to work with 5mm LEDs; use appropriate resistors or LED driver arrangements as required by your LEDs. Check available mounting space and secure the metal/plastic panel to avoid vibrationrelated issues during offroad use. Test each channel and the breathing flash function on the bench before final installation. What you get A 3channel remote control switch panel with breathing flash capability, compatible with up to twelve 5mm LEDs, constructed from metal and plastic as a replacement part for RC rock crawlers and other RC car/truck models.
