Chelhead 4-Gang RGB Switch Panel (12V/24V) with Relay Control Box for Camper, Car, ATV & Marine Use

If you’re adding extra LED lights, horns or other accessories, the usual wiring “tangle” can get old fast. This Chelhead 4-gang RGB switch panel is designed to give you a tidy control set-up, with RGB backlighting and multiple lighting control modes built around a 12V/24V system. On paper, it’s the kind of upgrade that makes a vehicle look more intentional, while also giving you practical switch behaviour.

That said, it’s not a plug-and-play gadget for every scenario. You’ll want to be confident about 12–24V electrics and simple relay wiring, because the value here is in the control box and how you integrate it, not in guided complexity.

The essentials

This is a 4-gang RGB toggle/momentary switch panel using silicone buttons for easier operation. It includes an on/off button, brightness controls and RGB colour controls, plus a control box that uses a built-in solid-state relay system. The panel is meant for vehicles and similar environments, with an IP65 waterproof label approach for the switch area.

The RGB backlight is presented as adjustable—covering multiple lighting control modes and brightness selection—so you can match the mood of your vehicle interior or dashboard lighting, rather than being stuck with a single glow.

What you’ll notice day to day

The switch behaviour is where this model tries to feel more “functional” than decorative.

It includes four lighting control modes described as: - Red-TOGGLE (always on) - Blue-MOMENTARY (press and hold) - Purple-FLASH (like a turning signal) - Green-strobe (like a warning light)

In real-world terms, that kind of mapping can be handy when you want different accessories to behave differently (for example, a strobe-style function for visibility or a momentary action for something you only need briefly). One small caution: because these modes are described in terms of the lighting/backlight behaviour, you’ll still need to confirm that the connected accessories you plan to run respond exactly as you expect through the relay control system.

Key specifications that matter for buying

It’s designed for DC 12–24V setups, with a stated max current of 60A. Power ratings are also provided depending on system voltage (720W at 12V, 1440W at 24V). Operating temperature is listed as -40℃ to +85℃.

It also uses a control box design with a one-sided outlet layout, intended to connect the positive and negative poles of the device. The control box includes a power source switch, and it can be powered by ACC or Battery.

If you’re thinking about fitting it on a camper, RV, truck, UTV or marine application, those details are the sort you should sanity-check against your existing wiring and accessory load.

Where it shines

This switch panel sits in the “modding” category: it’s built for people adding electrical accessories rather than those just replacing a broken dashboard switch.

Where it’s likely to make sense: - You want four separate switch “gangs” in one panel - You care about RGB backlighting, brightness and selectable modes - You’d rather centralise control with a relay-based control box than scatter switches - You’re working with a vehicle or boat-style environment where decent weather resistance matters

It also includes mounting brackets and a wiring harness, plus a circuit breaker and basic fitting items in the box. For many DIY installers, that lowers the risk of missing small parts mid-job.

What to watch before you buy

This is the part that can decide whether it’s a good purchase or a headache.

First, the stated electrical limits (max current and max power by 12V/24V) mean you should compare them to what you intend to run. If your accessories approach the higher end of the ratings, you’ll want to plan the installation carefully.

Second, while the control box is described as having relay-based control and ACC/Battery powering, the input about “compatible with” lists vehicle types rather than specific wiring standards. So, it may not suit every installation style without adjustments.

Finally, the product description mentions IP65 waterproof self-adhesive labels, but it doesn’t spell out how the whole unit itself is rated for submersion. If your use involves frequent splashes or heavy water exposure, it’s worth considering your exact mounting location and sealing approach.

The essentials for installation readiness

Before ordering, it’s sensible to check a few practical points: - Your vehicle’s power system is DC 12–24V - Your accessories’ current draw and power fit within the listed limits - You’re happy wiring via the provided harness and circuit breaker - Your mounting position allows for the intended relay control box placement

Worth noting: the package includes 140 DIY stickers, zip ties, a screwdriver and installation screws, which suggests a do-it-yourself installation rather than a highly bespoke fit for one vehicle model.

In the box (so you know what you’re getting)

The package is listed as including: 1 x switch control box, 1 x 4-gang switch panel, mounting brackets, 1 x wiring harness, 1 x circuit breaker, 1 x 140pcs DIY stickers, 10 x zip ties, 1 x instruction, 1 x screwdriver and installation screws.

If you expected a much more “blanket-ready” kit with vehicle-specific connectors, you may be slightly disappointed, but for general DIY wiring, it’s still a fairly complete starting set.

Mini FAQ

Is this suitable for both 12V and 24V vehicles?

Yes, the working voltage is stated as DC 12–24V, with different max power figures depending on whether you run at 12V or 24V.

What do the different RGB modes actually do?

The description lists Red-TOGGLE (always on), Blue-MOMENTARY (press and hold), Purple-FLASH (turn-signal-like) and Green-strobe (warning-light-like). It’s mainly presented as control modes for the panel’s behaviour.

Does it come with a control box and relay system?

Yes. The kit includes a control box and describes a built-in solid-state relay system, plus a power source switch (ACC or Battery).

Is it waterproof?

It references IP65 waterproof self-adhesive labels, but it doesn’t claim a full product IP rating for every mounting situation—so where you mount it matters.

When it makes sense?

It’s a solid pick if you’re building a vehicle or marine accessory set-up on a DC 12–24V system and you want four dedicated switch controls with RGB backlighting, brightness selection and multiple control modes, while keeping wiring more centralised thanks to the relay control box.

It might not be a great match if you need a totally drop-in replacement without wiring effort, or if your accessory load is close to the max current/power limits and you’re not comfortable planning around those figures.

It suits DIY installers who like having control over how the lights behave (toggle, momentary, flash and strobe-style modes). If you prefer simplest possible switching with minimal configuration, you may find it more involved than you want.
