for those who can see the details



Upside down head lights are not the do do here
the M6 stainless bolt fastens the bolt to the threaded stainless rack mount and a lock nut is on the back of all. So there is no way it can work loose and fall down. You can lock it up so you need a hammer, or you can adjust and lock the nut so one can still move the light by hand. I did tests to check the beam was not obscured by the wheel when designing the racks.
The light wires run inside the racks and also earthed (green wire) to the rack/brake boss and also earthed at the tail light to ensure there is never a bad earth and flicker.
The tail light wire runs inside the rack to the other side then to the frame entry point on the DT head lug. All is connected with spade connections with soldered wires then heat shrink, so all is demountable with ease. The feed wire passes into the fork via a reinforcement plate (those builders who do not do this on fork blades are heading for customer grief) into an annealed brass tube to the dropout.

I am bored with a straight tube, yeah, cheap and faster, but..................
Note the heat shrink covered light wire spade connection under the RH CS. A half cotton reel shaped stainless mount holds the connection





How many times do you see the routing and resultant loop doing an S bend, because they never gave it some thought
