Best Spdt Lighting Relays in 2026

Never go beyond its capabilities. Try to stay 10 to 15% below what the rate is for

12-volt 5-prong relay. Excellent water-repellent and dustproof ability, but not using it in water

Be careful when inserting the relay into the socket. If you force it, you will bend the female connectors

The 12v relay harness base contains 3*12 AWG and 2*16 AWG cables, length: 5.5 in, which have higher load-bearing capacity and more stable performance.

Function: 12VDC (14V Max) 5 Pin SPDT (Single Pole Double Throw) Relay with 40A/30A High Switching Capability.

Wire Specifications: White - Ground (85), Blue - VDC (30), Black - Trigger (86), Red - Output N/C (87a), and Yellow - Output N/O (87).

Never go beyond its capabilities. Try to stay 10 to 15% below what the rate is for

Please make sure you made tight connections (especially on the load wires)

12-volt 5-prong relay. Excellent water-repellent and dustproof ability, but not using it in water

12 V DC automotive waterproof relays (max 14 V). Note: 12 V and 14 V are coil voltages, they are not the voltage that triggers the switch

Premium quality: durable relay and harness socket with 5 wires; made from high-grade materials to ensure superior quality and long lifespan

Pre-wired Harness: Heavy duty 12/16 AWG wiring harness. Black - 16AWG Pin85, White - 16AWG Pin86, Red - 12AWG Pin30 Yellow - 12AWG Pin87a, and Blue - 12AWG Pin87

SPDT Relay - Single Pole Double Throw, you can use them to open or close a circuit -- or go from bright to dim on your headlights

30/40A Relay – It is rated to handle 40 amps of load at 12V DC in the Normally Open position (PIN 87), and 30 amps of load at 12V DC in the Normally Closed position (PIN 87a). You can use it in any circuit less than 30A

With the Wire Harness - Makes relay installation a breeze. If one goes bad, just unplug it from the socket and plug in a new one

1 piece 5-Pin 12V 30A SPDT cube-style Relay (size: 1.65" x 1.25" x 1.25", the time delay relay box is taller than regular relay box, please see picture-7 to confirm the size before buying)

Allow approx 10 seconds delay to turn on the light

Good for most car/motorcycle retrofit lights that do not have switch or want to delay the turn-on time to protect the battery or circuit/fuse, perfect for high power lighting applications such as LED light bar, LED work lights, HID system, etc
