Yes please read on from post here. Note you need to ensure the switchback LED's have internal resistor to simulate similar current load of filament indicator bulbs. Ditto if changing rear indicator bulbs to LED, this to ensure flasher rate remains the same.

End result here. Note picture taken at dusk so brightness exaggerated by camera.

Note also I don't identify the white lights in indicator position as DRL's. They are simply extra sidelights and as a sop to white van man. They remain on day and night since that's the OE condition on 3.7 Roadsters, and appear not to upset oncoming drivers at night given the low mounting position. The car has passed several MOT's since fitting without any mention either.
