Do you have to use a relay with LED light bar?
A relay is an electrical switch that lets a low current circuit control a high current circuit such as a large LED light bar. If you are using a light pod that does not have a very large amp draw, you may not need a relay switch, but if you are using a larger LED light bar, they are a must have.
What size relay do I need for LED light bar?
MICTUNING 12V 40A relay is a great replacement for light bar and suitable for most LED light bar wiring harness kit.
How do you hook up two lights to one switch?
You can do this light switch wiring in one of two ways. The most common is to daisy-chain the light fixtures by connecting them to each other and hooking the first one up to the switch. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a “home run” configuration.
How do you connect a light relay to a battery?
Then run a heavy gauge wire from the battery to the relay placing a 30 Amp fuse in line very close to the battery. Do not connect the power to the battery until all wiring is done. Then I run a single heavy gauge wire out to the lights or other accessory.
Can you run multiple off road lights off the same relay?
You need 2 seperate power wires. Otherwise your wires will melt and ground out and fry your battery and lights, or just catch on fire. No, you can’t run the new lights off the same relay.
Can you run two relays at the same time?
You can use the switch as the trigger power for 2 relays. The load to the lights shouldn’t be running through the switch, it should be fused power from the battery to the relay, then to the lights. . You can use the switch as the trigger power for 2 relays.
What kind of wire do you need for a relay?
In this case, you need to wire the dash switch in between the trigger current, i.e. the line you spliced off your high beam wire or your backup light wire. With our wiring harness, all you need to do is cut the wire coming from the switch to the 30 prong on the relay, and wire it to your high beam lead or your backup light wire.
