I don't know any of those lights.
In case you don't know already: There are no DRL, low beam and high beam connection on the front light.
They are all switched on an off via CAN-BUS. https://en.wikipedia.org/wiki/CAN_bus
That is not easy so be prepared for a challenge.
Something to consider is that in India the 125 isn’t fitted with the LED headlight whereas it is in other countries. It might be that they also run a different harness or it might be that there is provision for a normal headlight.
What’s wrong with the standard DRL on the Duke 390?
Are they not fitted in all markets? To be honest though, l would like the option to run with the headlight on all the time, rather than it only coming on when it goes dark.
Yes, I'm looking to add 2 additional front-facing DRL lights.
I was told by Twisted Throttle (online store) that the following would work:
DENALI DRL Daytime Running Lights With Universal Offset Mounting Kit | Amber Or White
DENALI DRL Wiring Harness With 3 Position Switch
DENALI 2.0 DataDim Dual Intensity Controller
"That wiring harness will allow you to install the DRLs on your bike, and control them with the switch. The DataDim Controller is also required if you would like to control the brightness at all."
I might try it.
While I can not speak to adding any lighting I can say that if you go into the menu on the Duke and turn DRL "off" it will put your full headlight on 24/7. The naming is kinda backwards from our thought process but DRL "on" is less light then DRL "off"
