Not sure what the objection is to using DRL as position lights. On my Roadster they come on with ignition as did the puny original 5 watt tungsten ones. If your car doesn't have the daytime on option then it's just a matter of turning them on via sidelight switch if you want to be better seen, much as I did with my M3W day or night.
I suppose some countries authorities may object to not having dedicated lights for both position and DRL but as suggested only the one is provided ex factory on the Roadster.
I agree with you Peter, the new factory fit LED headlamps do look the business but what is their price?
Richard. I have a feeling that DRLs became obligatory on new cars from 2011. Morgan probably was allowed more time because most of the cars produced in 2011 were existing models, for example my 2012 Plus 4 does not have them. Probably as soon as they changed engines, Roadster and GDI Plus 4 etc they would have been obliged to fit them.
One thing I don't really understand is why DRLs are only used on the front. I would prefer to have the tail lights on all the time too. On the current Roadster ex factory,
all sidelights (and number plate illum) come on with ignition, probably a spill over from the Mustang ECU/BCU heritage since the latter powers these lamps. From a practical point of view the permanent sidelight on feature seems pointless unless DRL's are employed instead to provide increased visibility, since ex factory the puny 5 watt in-headlamp lights are hardly seen in daylight. As you suggest maybe the rear lights on as well is helpful though.
FWIW the full LED lamps I'm using now employ the six outer main beam LED's to provide a DRL option, but on very much reduced power (1 watt v 24 watts). Heinz, who also has them, and I concluded that the DRL's do not dim or extinguish when (dipped) headlamps are turned on, but given this minimal power and the fact they are marked with E
8 approval, I see no reason for this to be challenged.
