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).

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

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
