Although not strictly daytime running lights as they are on permanently day and night, since that's how the sidelights from which they take their feed are factory wired on the 3.7 Roadster, you might consider
this switchback LED conversion. The bulbs fit in twin contact (stop/tail) holders fitted in front indicator position. All required loom wiring is already there close by. A worthwhile sop to white van mans inherent blindness to any vehicle smaller than his.
Before alarm bells sound I would like to point out that my car has sailed through three MOT's since conversion. This picture taken at dusk exaggerates the white light brightness but note the indicators are brighter.
