One of the features of my Milan GT that I really liked was the LED lights in the mirror covers. These acted individually as turn indicators and together as emergency flashers. I’ve been meaning to get around to adding LEDs to my Snoek-inspired mirror covers. There were a couple of small electrical issues to overcome but I think I’ve got them figured out.
Without going into a lot of detail, I came up with these 12V LEDs from Amazon that worked out well. I had to add a little structure to the interior of the cover to mount them. I 3D printed these covers using clear PETG, then painted the blue on all but the point. I also had to deal with the fact that the DF electrical system is based on a 7V battery. These LEDs require 12V. So I had to do some funny business to bring in 12V for these LEDs and the ones in the hood side markers.
I used hollow Sturmey Archer brake cable adjusting screws to mount the mirrors. This allowed me to pass the wiring to the LEDs through the screw without having to drill any more holes in the body.
Here are some photos of a mirror cover
I use the same LEDs in the hood side markers.
