Right hand front parker/DRL LED light flashes once and then turns off after car has been locked for a while when you go to unlock vehicle. Left hand light comes on and stays on.

They are for unlock illumination around vehicle at night

Checking of vehicle confirmed LED flashed once if vehicle had been locked for a period of time.

If vehicle was locked and left for a short period of time the LED would flash once the DRL would come on and stay on. If vehicle locked then unlocked straight away the LED would come on and stay on. Checking of rear of vehicle found that right hand tail light would do the same as the front.
