Must look into this option. I have also been aware of the need to be seen, especially in a Morgan so I took the simple route some years ago and always run with my side lights on fitted with bright long life LED bulbs. On the general subject t of DRL's on cars I have always been amazed that regulations require front only. The number of times I have driven down the M1 in heavy rain and poor visibility to see cars with only their front DRL's on. Drivers obviously thinking 'oh I can be seen alright'. No lights showing at the rear of course!
