Requesting help in wiring new LED Aux lights

Hey guys,

I bought new LED aux lights and I am just kind of lost when it comes to properly wiring them.

So far, I will be installing the following things.

ABS- shut off switch

Headlight relays with one headlight cut off switch.


My question is, which route do I take to wire in my Aux lights?

I would love to have full control over them. So that means that I would just be able to turn them on and off on command.

From what I gather, I would need to use a relay and a switch to get them wired in like that.

I would like to wire in them also to a switched power source. Where could I tap into one?

Both light combined would be drawing about 45watts.

What kind of a relay would I need?

Appreciate your help.

I built my own harness and wired them directly to the battery through a trail tech push button switch fused at 5 amp. Mine are 12w each in old trail tech MR16 housings. I wanted them on while the bike was off to light campsites at night while setting up. LED's dont have to go through a relay unless you want them activated by switched power. They dont pull enough amps to matter. It makes for a clean trouble free install

That's another consideration I was having. It would be very useful to have it set up like that.

I am worried however of for example parking a bike somewhere public without a cover and some curious passerby turning them on for sh!t and giggles. Then I am stranded with a flat battery.

If you wire direct make sure you install a LED indicator light for when they are on. I am about to do it this weekend, dont ask.

Otherwise advanced auto sells the relay and pre wired relay plug. Pretty much plug and play. Thats how I hooked up my digital voltmeter.

Howdy, what I did was run a 10 guage wire from the battery to the front of the cowl, one red one black. There is a fuse on the red at the battery for 30Amps.
That wire at the front then got connected to relays, one for lights (switchable), one for a horn, will eventually do one for headlights (hi and low) once I get some LED light H4 inserts.
So for me, it is a wire from the battery and a switch to turn the relay on and off at the front.

Wait so, with that setup(direct to battery+relay) can you still turn on the aux lights when the bike is off?

What kind of relay did you use?

For what it's worth , I jumped off my E/B headlight harness on the low beam side (Yellow=low , Black=ground) and now have awesome lighting that really is noticeable during the day and provides a boost at night. Not tied into high beams , just low.

Lord , if I have to look like a Power Ranger , can it at least be Amy Jo Johnson?

You probably could, but I used a switched (by key) power source for the toggle that turns on the LEDs, so if the bike isn't turned on, the relay is open.
30 amp four pin relay.

Stuck :( Can't get the relay/switch to work

Okay so I am stuck with my wiring.

Here's what I have done so far.


I have a SPDT 5 pin relay.

30 ----> Positive battery terminal

87 -----> Positive from both LED lights

85 ------> black cable from a switch

86-------> positive cable from a switch



Black negative cable from LED lights is directly connected to the negative battery terminal.


What's the hell am I doing wrong?

If I connect the positive to the 87a terminal on the relay while the 30 terminal is powered by the positive form the battery the lights work. But the switch does not.

If somebody can help me out in all of this I would be deeply grateful.


I am using a 5 pin relay because that's the only one I have. I don't care about the 87a capability. I basically just want to use it as a basic 4 pin relay.
