Denali S4 Lights on/off warning light

[Engineer]

I recently installed a pair of Denali S4 lights with a DataDim controller. Picked up the main beam trigger wire ok and used a relay to get a +12v signal. I used the supplied wiring harness and installed the on/off switch on the left side of the handlebars. The installation was all ok and everything works as intended.

Now having ridden the bike in daylight,  I find myself wondering whether the lights are on or off.

I would like to fit a small LED warning light to indicate when the lights are on. I have checked all the pins in the 6 way connector at the DataDim trying to find a wire that goes on and off with the switch. Completely baffled.

Anyone with electrical knowledge know how to solve this problem?

The data dim probably uses low voltage ( High or Low) circuits to switch on and off.

 

You said you used a 12v relay so just piggyback on the +12dc output connection with an LED rated for 12v.

 

Or wire it in parallel to the Denali Lights +12vdc input to the lights.  Whenever they are on, your LED would be on.
