How to Wire an LED Light Bar Properly (Project Night Light Episode 3)

How to Install a Light bar. In this episode of Project Night Light, I show you how to wire an LED light bar properly using a relay. I go though every step so after watching this you will know how to wire any auxiliary light you want. At the end of the episode I show how insanely bright the light bar is!

    Lol you don't need 2 cables for 1 switch if you use relays. You can bridge positive between the switches. You just need 5 cables for 4 switches

    Since some people like to drive with light bars turned on while on the highway and back roads, the proper way to wire them is by running power from the high beam circuit in series with the switch powering the relay coil. This way the light bar can only be powered up when the high beams are on and will go off with the high beams. The switch still allows the light bar to be off when not being used in conjunction with the high beams. This is actually legally mandatory in some places.

  19. Santiago Dmngz

    Santiago DmngzUukausi sitten

    So it’s necessary yo have 2 fuses, the one from the switch (between the switch and the power for or) and the one between the relay and battery?

    For those who didn’t understood why there’s ground wire in the switch because there’s a bulb 💡 inside the switch it self . For the switch to lit 🔥 u need positive and negative. Switch it will work without ground as well ,but it won’t lit red at dark

    My ute is probably bigger than your ute (Plus it's also bigger than cars). Because how because I have a Mercede-Benz Sprinter Ute that has steel wheels. But now I brought a 48000 Runer Muster and it has 2 wheels at the back and my parents are gonna out a box at the back because they're gonna use it for the university. Where were gonna go to Universiting it's at Harvest Launceston. A Travel to Launceston can take long because I am so for away from Launceston. Our Sprinter Mercede Ute has no temp guage, But our Runner Muster has a temp and fuel guage. My runner muster has 40k Kilometres (I am not American so I don't say Miles). The Tachometer is kinda smaller than the Speedometre (I'm not american so I don't say Odometer and Speedometer, I also don't say gas because that's USA too). But the problem is I don't know what fuel it has. It doesn't have a thief alarm but when thiefs try to start it, the engine will just turn over, but it just wouldn't start, almost like a turned on kill switch like on your cars. My Sprinter ute uses diesel fuel so I bet runner muster uses diesel fuel. Where the runner muster is it's at Cairns, Queensland, Australia (Don't try to steal it)

    Great vid as always and love the whole channel! Just thought I'd mention something as I'm an electrician and the switch wiring made me go 'what?' for a sec. If the 12v feed from the fusebox was in the centre pin of a standard (no LED) switch, it would ground the battery in one of the two switch positions, blowing the fuse. In a bog standard toggle switch pins 1 and 2 are connected in one position, pins 2 and 3 are connected in the other. So if you used such a switch with the connections suggested here it would not work and would be very dodgy, especially if plugged in without a fuse. I did a quick google and see the correct pinout of the LED switches usually used in automotive is as in the video, the internal circuitry is wired for that connection scheme. But just in case someone thought that 'this is how all switches with 3 pins are wired' and tried to use another sort of switch I thought I'd point out that the standard config of a toggle switch would lead to blown fuses (hopefully at best). General rule, just double check the pinouts and make sure you know what goes where and don't connect the battery to ground ;) No fault with the vid, just thought I'd add in that extra info!

    I've always found it easier to use the oversized zip tie and just tape the wire to the end of it as you pull it through then no chance of poking a hole in your the rubber boots Bad place to mount the switches on count when in movement you could always accidentally bump it which shuts it either off or on and it also takes up so much door space and just looks ugly off of one side that is my personal opinion

    One thing that you forgot to address when using an "add a fuse" wire, if it's plugged into a slot with an existing fuse, the existing fuse must go on the inside, and the new fuse (of equal or lesser amps) must go on the outside.
