3 Pieces LED Lighted Rocker Toggle Switch (Blue)
These 12V LED toggle switches offer SPST operation with a three-pin blade terminal configuration. Rated at 20A, the blue LED indicator lights when the switch is ON, improving visibility in dark environments often encountered in boats, RVs, or vehicles. The body is built to resist corrosion, and the package commonly suits marine and automotive dashboards or console panels where quick status checks matter.
Applications include auxiliary lighting, blower motors, or accessory circuits where a blue illumination helps denote a specific system. The 12V LED glow is designed to remain visible during nighttime operations, and the three-pin design simplifies wiring. An economical way to add illumination without sacrificing performance, these switches are ideal for multi-switch panels in trucks or boats.
Considerations include verifying the panel cutout and ensuring the device’s current rating aligns with load expectations. While 20A fits many accessories, higher-draw devices should use a higher-capacity switch consistent with electrical safety practices.
DaierTek Red 12V LED Lighted Toggle Switch
This red LED illuminated toggle switch from DaierTek is a 12V DC, 20A heavy-duty option with a three-pin SPST ON/OFF configuration.

Buying Guide: 12V Lighted Toggle Switches
- Current rating: Match the load to the switch rating (20A, 30A, etc.). Exceeding ratings can cause overheating and failure over time.
- LED color and visibility: Blue and red indicators are common; choose a color that provides clear status signals in your installation environment.
- Mounting size: Verify mounting hole diameter (commonly around 0.47–0.48 inches or 12 mm) and ensure your panel cutout accommodates the switch body.
- Construction and durability: Look for metal or reinforced shells and weatherproof seals for marine or off-road use. Bakelite or reinforced plastics offer different resistance profiles.
- Wiring configuration: Most options use SPST with three pins. Ensure wire gauge and terminal type (blade or fast-on) fit your harness.
- Environmental suitability: Waterproof or water-resistant designs are essential for boats, boats, and outdoor installations exposed to moisture.
- LED behavior: Some models illuminate only when ON; others light continuously. Consider whether you need ON-state indication or always-on visibility for safety checks.
- Color coding across a panel: If you’re wiring several switches, consistent LED colors help differentiate functions at a glance during night operations.
- Panel integration: Check for round vs. rectangular shells, mounting depth, and whether a protective cover is included to guard against dust and moisture.
In evaluating options, consider the intended environment (auto, marine, or off-road), desired LED color, and whether you need a pack of multiple switches for a single project. A higher-current model may cover more devices, but ensure the wiring and battery capacity support sustained use. Finally, verify compatibility with your existing control panels and harness adapters to streamline installation and reduce integration time.
