I'm adding an extra pair of LED spot lights mounted to my engine guard on my Limited. I want to tap into the high beam power to the headlight to trigger a relay for these extra lights. Does anyone know if this will cause a problem with the CANBUS?

I tried to wire in a relay for low beam, and a relay for high beam on my CANBUS 2012 dyna, but it didn't work. When switched to high beam, it work only flash high beam for a moment, then revert back to low beam.

Hoping I don't have the same issues on the Limited.

 

If you use Led spotlights that do not exceed 10 watts (less than 1 amp drive current) each and your high beam is also Led you don't need a relay: you can tap directly into the high beam wire and power your spotlights.
I have done it on my 2014 CVO limited and it works very well

 

They are each 70w (7x10w). That's why I need to trigger a relay.

 

Well now I know the answer.

The lights shown above are mounted using Harley highway peg clamps mounted to the front crash bar. Since each light draws 70w, I wired in a relay which is triggered by the high beam with an inline switch so I can still use hi beam without the LED spots.

The next 3 photos are all with the factory side lights turned off:

1. Low beam only




2. High beam together. Not much different except fot the bright spot in the middle.



3. Low, High, and both LED spots.



I just returned from a 5 state round Australia ride. These lights made riding at night enjoyable, but still very risky.

 

Is that a Ridgid brand LED?

 

Your low beams stay on with your high beams? I need my SGS to do that!

Also, you cannot show cool lights like that without posting a link!

Please share.

 

Nah. Low beam does not stay on. Take a closer look at the first 2 pics. It's a day maker led headlight with 4 LEDs. The2 side LEDs stay on with either high or low beam. I'm planing to run low beam from a switched accessory wire, and then it will stay on when high beam is selected.
