Drl Light Not Working T120

Was asked by a chap I rode with the other day. Said you have no daylight head light on.
He's right, no light.
Is it a change of bulbs or fuse, anyone had this issue?

 

Thanks, I'll check the wiring at the headstock as I have been moving some about for the new handlebars.

 

Good news is that the connector had come out, bad news is that the retaining clip is broken off.
I've heat shrunk some heat shrink onto it so it has something to grip.

 

Thanks for the recall notice. I had this done just before triumph sent out the letters.
