Richard, thanks for the impressive pics. How do you wire the day drive light? Does it get power via the first stage of the switch, so that it is controlled by the side light? Because then the rear lights are also on during the day? Or is it an extra wire that is switched on via the ignition?
See answer above Heinz.
To add though the current Roadster has front and rear sidelights permanently on with ignition feed, so wiring up as suggested gives automatic daytime lights. There is no further side/position light mode with these particular headlamps and no dedicated feed for such in tbe Morgan loom anyway. Switching the sidelights on with light switch does nothing other than dimming panel lights when driving.
