With all of that in mind, was contacted by a company called Co-light to do a review of their Rob 2 Pro driving lights. These are a dual beam light with a single on and off switch (no high/low beam) which is exactly what I was looking for.

The Rob 2 Pro retails for $97.00 and is currently on sale for $78. The kit comes with 2 Rob 2 Pro lights and some simple mounting hardware.

Wiring Harness

The wiring harness can be purchased for an additional $21.99. At the time of this writing, the only wiring harnesses available from Co-light are three wire in nature and the Rob 2 Pro lights are two wire. I am told that a two wire harness is in the works, but for now you will have to use the three wire, or create your own. In this blog, I will show you how to wire both the three wire harnesses to your lights as well as create your own custom version.

Assembling the Custom Mounts

I then used the Co-light bracket and drilled out the hole to accept the threaded RAM ball. 

The Co-light bracket is made with protrusions that would hold a nut in place. We need to fill the gap between the bracket and the top of the protrusions. To do that, I took a 10M washer and flattened it out with my grinder to fit the slot. I then painted them black. 

I then installed the modified washers, a thin copper washer and the fender nut to the threaded end of the RAM ball.

NOTE: The nut show here is larger. I replaced this with the jam nut indicated above.

Once I had the ball attached to the bracket, I then clamped the RAM ball to my crash guards and installed the extension arm. After repeating this on the other side, I was now  to mount the lights.

With the exception of the hot, ground and trigger wires, all other connections are made with easy, screw on connectors.

Wiring the Pig Tails to the Lights

The first thing you will need to do is to add the pigtails to the lights. As I mentioned above, the lights themselves have two wires and the harness has three wires. 

Which Wires to Use?

The first thing you will need to do is to add the pigtails to the lights. As I mentioned above, the lights themselves have two wires and the harness has three wires. 

The harness uses a red wire (hot low-beam), yellow wire (hot high-beam) and a black wire (ground). The Rob 2 Pro lights only have the red and black wires.
 

To use the harness you have two options.

1. Leave the yellow wire unconnected (as in the image above).
2. Wire the red and yellow wires together (what I suggest). 

Leaving the yellow wire unconnected will cause the switch to operate on every other click. Wiring the red and yellow wires together will allow the switch to work each time it is pressed, tuning the lights on and off. You can see how this works in the video accompanying this blog.

Connecting the Pigtails

Using the pigtails as an example, I connect the red hot wire from the light to the red and yellow wire of the harness. 

I suggest using a solder and seal connector to join the three wires.

 

How to Position the Wires for Heating

This is an example of how to join the three wires.

You will also have to join the black, ground wires, so you should strip the black casing off the harness to give yourself more room.

 

Joined Example

Here is an example of how three wires join in such a manner would look after heating.

Don't Forget the Shrink Tubing

To finish off the join, I always finish off with a length of shrink tubing. It just makes the install look more professional and gives an extra layer of water protection.

Make sure you slip the shrink tubing over the wires before connecting them. 

Test!

Before continuing, I suggest running a test to make sure your connections are good between the lights and the pigtails. You can do this by connecting each light (in turn) to the battery. 

Red Wire (Hot)

The red wire from the harness goes to the positive terminal of your battery.

NOTE: In this image I connected the blue wire to the positive terminal for testing.

DO NOT DO THIS! THE BLUE WIRE SHOULD GO TO A KEYED CIRCUIT.
 

Black Wire (Ground)

The black wire from the harness goes to the negative terminal of your batter.

Blue Wire (Trigger)

The blue wire is the trigger wire and must be attached to a “keyed” hot wire. A keyed wire is one that is live only when the bike is powered up.
 
Refer to your bikes wiring diagram to locate a good keyed trigger location.

In the past I have used the wire that powers the light over my license plate or a keyed accessory power port. You will need to find the location that works best for your motorcycle, but make sure the wire is only hot when the bike is powered up otherwise you will eventually run down your battery.

Posi-Tap

To attach the trigger wire, you can use a “Posi Tap” or some kind of “vampire clamp.” 

Why Use the PDM60?

The benefits of the PDM60 is that it isolates all of your accessories from the bikes main electrical system and eliminates the need for separate fuses and relays each time you add a new piece of equipment. 

Steps for Creating the Harness

Measure and Cut Wires

I measured and cut the wires for both sides. The length was slightly different due to routing. I made sure to leave plenty of extra (I will trim later).

Add Terminal Connecters

Female connector goes on the lights and the male on the wires leading to the battery.

Cover Wires with Shrink Tubing

Once I had the connecters in place and I had tested to make sure every thing worked, I determined where the two side would be joined together. I then covered both lines (red and black wires with shrink tubing up to the join location. You could use electrical tape for this step.

Join the Red Wires From Each Side Together

To the right is an example of how I made the join using the Solder and Seal connectors.

I also covered this join with shrink tubing.

Join the Black Wires From Each Side Together

I used the same process to join the black wires together and finished it off with shrink tubing.

The result of these two joins was a single red line and a single black line that would be tied into the PDM60.

Join the Red Wire to the PDM60

I then selected a circuit on the PDM60. I used an open 15 amp circuit which is more than enough. The lights draw about 3 amps each.

I then cut and joined the using a Solder and Seal connector and covered the join with shrink tubing.

Join the Black, Ground Wire to the Common Ground Terminal

The PDM60 uses a common grounding post attached to the battery's negative terminal. I added a terminal ring to the black wire and added it to the common ground.
