Baja designs LP6 wiring

[Mason09]

Hey y’all, I just got 3 LP6 pro driving/combo lights that I’m going to mount on my front bumper. I didn’t realize these have a high/low beam before buying them so I figured the wiring was going to be identical to my LP4s. I have aux 1 available which I’ll wire the high beams as I’m assuming they draw the 6.5amps each per BajaDesigns.com. However, I’m interested in wiring the low beams as well to use for foggy days. Can I wire the low beams to one of the 10am switches?
BD also states if you run power to high and low at the same time, it will kill the circuit boards on the lights which also makes me nervous to have them wired separately in the off chance I accidentally hit the lows while highs are on or vice versa.
Any help/clarification is greatly appreciated!

I’m sure that someone will chime in with a harness that you can buy…

but you can easily create your own wiring harness using two five pole relays!

Say Aux 1, Low beams. Aux 2 is High beams. The switch amperage is irrelevant now that we relay.

Hook up Aux 1 to Relay 1, as you normally would. Hook up Aux 2 to Relay 2, as you would.

On Relay 1, Take the relayed output (87) of and plumb it into the battery input (30) of Relay 2.

Now on Relay 2, you use hook the Normally Closed (87a) circuit to the Low Beam and the Normally Open/Relayed/Switched Circuit (87) to the High Beam.

When you trigger the the Aux 1, Low beams come on. When you trigger Aux 2, low beams immediately disconnect and high beams come on. The best part of this is that you can leave Aux 2 energized and nothing will happen till Aux 1 is switched - acting like a main circuit breaker and it retains the last known lighting level.

I would advise to place the relays in a dry area of the engine bay, coat them in dielectric/electrical silicone sealant to avoid corrosion or freeze up

Very helpful! Now my question is whether a 10am aux switch can handle the low beam draw as my LP4s are already drawing power from aux 2.
Or does adding the relays create a safety net that allows heavier power draw to the lower amp aux switches?
Sorry, I’m a rookie when it comes to electrical work

You hook the relays up to the battery, which it pulls power from. This line, which you will have an inline fuse on (the max the relays can handle, 40A?) carries the actual load/current. The Aux Switch will only see about .2A draw to trigger the relay.

The relays come in different amperage ratings too, for my dual LP9s I ran with a pair of 30/40 relays. 30A on the NC/87a circuit, 40A on the NO/87 circuit. Another common relay is the 20/30 - but like a fuse, you need to figure out the total load and base the system around max draw

The wiring diagram in the previous post shows you how to hook up a single relay. My meth rod for the High/Low beam is almost the same thing twice

Furthermore Edit:

LP6Pros pull 7.5A each. Lots of headway on a 20/30A relay! With some rough math for a triple LO6 Pro Setup, the low beams should pull about 7.5A, high beams will pull 22.5A

Ok thanks! I read on BD.com that each LP6 pulls 6.5amps so couldn’t I merge the wires from each light (total of 19.5 amp) to one relay that is connected to the second relay to separate the high and low?
Also, thank you so much for the details!

Yes, you can daisy chain everything together. Just be sure spec the wire gauge for the length of run vs the max current it will see. When you are wiring in a relay, you are wiring in two circuits, the switch line and the high energy line. We are now wiring in a third circuit and doubly relaying the system - it’s a little complex and easy to “get your wires crossed”. If any of these terms are new to you, either get familiar with them or consider and off the shelf harness - so that you don’t fry the new lights

Crap, yeah 7.5amps! Sorry.
And yes, I’m running 12guage wiring per the wiring instructions with the lights. And I’ll run 14 gauge for the backlights since they hardly draw anything.

your original diagram and instructions seem somewhat easy once I daisy chain the high beams together to run to 87 and then do the same with low beams but plumbed into 87a. Then have the relays connected to each other with relay 1 directly attached to the battery. Obvious each relay connected to the designated aux switch.

Another question, does there need to be a fuse attached to the positive wire going into the first relay? Or does the relay handle that?

And would these relays be overkill?

You could always use one relay and wire it like this:

If wired up like this, Aux 1 is basically your main power. Flip Aux 1 and your Highs come on. If you want low beam, flip your other Aux Switch. Leave other aux switch flipped on, shut off Aux 1 and lights off. Flip Aux 1 back on, low beam on until other Aux is switched back off now back to high beam.

Aux 1 is power to lights
Other Aux switches between high and low.

Hopefully that all makes sense.

That does make sense. And I could swap low and high beam so that the lows come on with power and highs are the option, correct? I think I’d prefer the lows be the starting point so I could leave them on when needed and then bump power to the high beams.

Yep, definitely. And that's what I would do too!

You'll want to use the lock out harness:

https://www.4x4truckleds.com/baja-designs-lp6-lp9-series-upfitter-lock-out-wiring-harness/

And since you have 3 lights you'll need a splitter as well: https://www.4x4truckleds.com/baja-designs-lp4-lp9-sport-splitter-harness-universal/

The lock out harness pulls power direct from the battery and gives you 2 leads. One for high beam (all lights) and one for low (bottom series). It ensures you don't power both circuits at once as well if both switches are on.

Keep in mind LP6 are NOT street legal and you WILL blind people on the road if you run them

You can message @Baja Designs on the forums and they're super good to work with as well.

No shade on 4x4led whatever but I like dealing directly with the company, especially when problem solving. I hope that wasn't taken wrong.

SERIOUSLY. They're crazy bright. Great call-out. Too many people running light bars at dusk/night blinding everyone on the highway.

Very aware they’re not street legal. I have LP4s on my a pillars and they turn night into day. LP6s are going to be even more intense so obviously not going to run them on the road. I’m probably going to run my own wiring. I appreciate the links
