Nilight – 90001B LED Light Bar Rocker Switch
Features: Easy to install and use: 5 pin on-off rocker switch with SPST design (single pole single Throw), simple installation, freely turn on or off the light. Cool illuminated light: built-in two premium LEDs Emits soft light to illuminate the patterns, easy for you to find the switch in the dark. Sturdy and durable: made of high-quality plastic and well-conductive pins; laser-etched pattern, not easy to fade away.
Best for: Off‑road enthusiasts and vehicle owners who need a compact, clearly lit switch for dark cabins or cargo areas. It’s a solid, easy install for Jeeps, boats, and trucks.
Limitations: Primarily a standard SPST design; check wiring compatibility with your 12V or 24V system. Not a full harness; you’ll need jumper wires or a separate harness for complex setups.
Round Rocker Switch, 12V SPST 3 Pin
Features: Special design for 12V applications with SPST ON/OFF and 3 pins. Includes a waterproof cover, making it suitable for marine, automotive, RV, and boat use. The blue LED indicator lights when ON for easy visibility in low light. Made with durable plastic and brass terminals; waterproof and dustproof.
Best for: Users who need a rugged, marine‑grade switch with visible status in dim environments. The waterproof cover adds reliability in wet conditions.
Limitations: 3‑pin design means terminals differ from 2‑pin models; ensure you match wiring to the correct terminals in your harness.
LED Light Bar Switch ON/OFF 5 Pin Laser Marine Rocker
Features: Function: 5 pin rocker switch SPST with jumper wires. Rating: 20A 12V DC; 10A 24V DC. Dual LED: blue LEDs illuminate both the word and pattern parts when ON, aiding visibility and status indication.
Best for: Applications where a large, clearly illuminated switch is desired and jumper wiring is included for easier installation on cars, boats, ATVs, or UTVs.
Limitations: May require a compatible mounting space and compatible 12V/24V wiring harness. Ensure jumper wires are properly insulated to avoid shorts.

Buying Guide
What should I consider when choosing a toggle switch for a light bar?
Voltage and current ratings should match your light bar’s requirements. Look for SPST or SPDT configurations based on how you want to wire the circuit. Waterproof or dustproof ratings are important for outdoor or marine use. Illumination helps in low‑light environments and improves status visibility.
Do I need a wiring harness with the switch?
A harness with a relay and fuse provides overcurrent protection and easier wiring, especially for high‑current light bars. For simple, low‑power setups, a bare switch with jumper wires may suffice.
Is illumination a must for all switches?
Illuminated switches improve visibility in dark cabins or dashboards but add a small power draw. If energy efficiency is critical, choose a switch with a minimal LED setup or none at all.
Which materials matter most for longevity?
Durable plastics, brass terminals, and fully sealed housings offer longer life in harsh conditions. Marine and off‑road environments reward switches rated for waterproof and dustproof operation.
How should I compare options?
Compare by voltage/current rating, mounting hole size, illumination type, and whether a harness or jumper wires are included. Consider how the switch will be integrated with your existing dashboard or control system.
FAQ
What is SPST in a toggle switch?
Single Pole Single Throw. It controls one circuit with two terminals: on and off.
Do all light bar switches need a jumper wire?
No, but some models include jumper wires for easier installation; others require a direct harness connection.
Are illuminated switches better for dark environments?
Yes, illuminated switches help locate the control in low light and indicate when the circuit is active.
Is a wiring harness necessary for marine use?
Not always, but a harness with a relay and fuse increases safety and reliability in saltwater or wet conditions.
What mounting hole size should I measure?
Most 12V rocker switches use around 20mm or 37mm x 21mm; verify your dash cutout before purchasing.
