Randpow 12V Fuse Block for Motorcycle & Car — 4-Circuit 20A Relay Protected with LED Indicators

Compact 12V fuse block that centralizes up to four accessory circuits with 20A total output, relay protection on the ACC line, and LED status indicators for quick diagnostics. This Randpow 12V Fuse Block is a tidy, splash-resistant power distribution solution for motorcycles, cars, boats, ATVs and other 12V systems. It replaces messy wire taps with a single battery-fed terminal that supports up to four fused circuits, adds a relay-controlled ACC line to cut standby power, and shows fuse health with colored LEDs. The result is simpler installs, clearer troubleshooting, and improved long-term reliability for auxiliary lights, horns, chargers and similar accessories.

How does this unit simplify wiring on my bike or car?

The fuse block gathers multiple accessory circuits into one compact assembly that connects directly to the battery rather than tapping many factory wires. That reduces clutter, lowers heat and voltage drop on original harnesses, and makes future changes or additions straightforward.

• Single positive terminal for battery feed streamlines main power connection.
• Four organized fuse positions eliminate scattered inline fuses.
• Mountable housing keeps wiring neat and more serviceable.

What protection features are built into the kit?

Protection is provided by blade fuses for overloads plus an ACC relay that removes power from accessories when the relay is off—reducing parasitic drain. The enclosure is flame-retardant and splash-resistant to protect connections from moisture and vibration.

• 20A total output with individual fuses to isolate faults quickly.
• Relay on ACC line cuts standby current to prevent battery drain.
• Heat-resistant PC shell and push-latch cover guard against dust and splashes.

How can I tell when a fuse blows or needs replacing?

Each circuit has an LED status—steady blue indicates normal operation while red signals a blown fuse. That makes fault-finding fast without removing the cover or using tools; swap the affected blade fuse and you’re back in service.

• Blue LED = circuit OK, visible through cover area.
• Red LED = blown fuse; immediate visual direction to the failed position.
• Tool-free fuse swaps: quick maintenance roadside or in the garage.

How easy is installation and what devices can I run from it?

Installation is straightforward: mount the unit with tape or zip-ties, hook the solid red to positive, black to negative, and the thin red to ACC. It supports many 12V accessories used on motorcycles, off-road vehicles and small boats for simple expansion of electrical systems.

• Includes mount-friendly housing for double-side tape or cable ties.
• Compatible accessories: LED bars, fog lights, horns, USB chargers, and more.
• Wiring labels and color-coded LEDs make setup intuitive for DIYers and pros.

Who is this for This Randpow fuse relay block is for riders and drivers who want a cleaner, safer way to add accessories without overloading factory wiring—DIY mechanics, aftermarket installers, and anyone fitting extra lights, chargers or horns to a 12V platform. It’s especially useful when you need simple diagnostics, relay-controlled ACC power, and a compact, weather-resistant enclosure for exposed or vibration-prone installations.

FAQ

Q: Can I use this fuse block for LED light bars?

A: Yes. It supports 12V LED bars and accessories, but ensure combined draw stays within the 20A total output and individual fuse ratings.

Q: Does the relay prevent battery drain when vehicle is off?

A: Yes. The relay on the ACC line cuts standby power, reducing parasitic drain from connected accessories.
