drill holes in the ditchlights and thru the pilot

 
 view from the underside with the holes

 
 make a "lens" on the "fibre optics" with a soldering iron
 IMPORTANT: dont touch the fibre optics with the iron
 go only as close as possible and you can see that the
 heat from the iron "forms" a lens...
 place the "stil warm" fibre optics right in place
 so the lens goes in to the ditch light hole

 
 view from a different spot

 
 bend the fibre optics with the heat from a soldering
 iron (again, dont touch the fibre optics with the iron
 go only as close as possible, if you touch the fibre
 it will loose the possibility to bring the light from
 the LED to the ditch light and you have to start again)

 
 bend the fibre optics as you can see on this picture
 and glue it in place with a two component glue

 
 here you can see the mechanical work on the drives.
 for headlights and pilot mounted ditchlights you have
 to made one recess, if you have noselights and pilot mounted
 ditchlights you have to made two recess

 
 drive is ready with one SMD bright white LED

 
 this is the result, looks prototypicaly...

 
 both drives are ready for the modificated shells
 and frames - why I use two LED's ? - with DCC you
 have the possibility to turn the LED's separate
 on, so you can drive with the head/nose light only
 or you can turn the ditchlights on too (nice
 feature...)

 
 inside of the nose with noselights

 
 this is the result, looks prototypicaly...
