Can I wire my LED light bar?
You’ll most likely be wiring your LED light bar relay’s power lead directly to the battery, but you won’t necessarily use the same battery’s negative terminal as your ground. You can ground your wiring to the vehicle’s chassis, as long as it offers a clean connection between your circuit and bare metal.
What size wire do I need for a LED light bar?
LED Lights are expensive and in all cases should be protected against early burnouts. OPT7 Wiring Harnesses achieve this by using silicon infused 14 American Wire Gauge (AWG) cables that better control against voltage spikes and heat.
Do I need a relay to wire a LED light bar?
So in short if you do not properly wire the light bar to a battery and use a correct amperage switch which will keep the light bar on it’s own independent circuit a relay is unnecessary. However if you tap into the high beams or another lower voltage switch then you will need a relay to avoid an electrical fire.
Can you wire 2 LED light bars together?
Can you hook 2 light bars to one switch or will it blow the fuse and relay ? You can hook as many light bars into one switch as you’d like because, if you’re wiring is done properly, the power for the accessory should NEVER go through the switch.
Why does my LED light bar have 3 wires?
LED Lights with 3 wires will be a multi-function light. They can (most times) be used in whatever configuration is right for your application. For example, running and brake, running and blinker or brake and blinker. These LED’s will usually have a black, red and white wire.
How do you hide LED light bar wires?
How to Hide Roof Rack Light Bar Wires on Windshield?
- Drill a hole in the roof and run it down the a-pillar (inside the vehicle)
- Run wires through your weather stripping and windshield (see that option here)
- Run wires down the front of your windshield in a bulky wiring loom (see that option here)
What is the yellow wire for on a LED light bar?
Figured it out, yellow wire is for amber. That is what i wanted it for and they are bright! I am not using the red wire but if you want to switch between white/amber it comes with a wiring harness that i did not use. There are no instructions for the harness and it is not using conventional red/black/white wiring.
What size fuse LED light bar?
A 10 amp fuse will protect the circuit. The 16 gauge wire will handle 10 amps in the length of wire that you will be using. The switch is rated for 20 amps. So, the 10 amp fuse will protect the circuit from overload.
Why do LED light bars have a relay?
Relays can be used to switch a low-current trigger to high current, switch a circuit on or off, reverse polarity, and much more. When adding LED lights, such as off-road light bars, driving/work lights, or other auxiliary lights to a vehicle, you must add a circuit to power the light adequately.
How many amps does a LED light bar use?
55W LED lights are usually in 4-5 amp range. You can also use a high current meter.
