2016 mustang drl boards from diode dynamics ????

Lets make this short and easy . There are 3 drl boards per headlight . They worked fine for a week and now 1 of the 3 lights dont turn on in the morning but at night it works sometimes all of a sudden. Why could this be . But the sequencer function works everytime . Thats why im so confused

At night the dimmed parking light mode is on, so it is a different wiring and mode than the DRL function.

Do you have a EU or US Mustang? Did you bought the right board version for it?

How did you wire the boards?

I wired it the way i was instructed to by the company . And i bought the right lights (u.s). And all the lights are wired the same so why 1 out of 6 dont work i have no clue . But sometimes all of them work. All the wires are hooked up to 1 plug and that plug clips into a driver and then just hooked up to a constant power and accessory and is controlled by bluetooth
