I'm thinking of making some of these but have the lenses sticking out a little further to get the 60 degree viewing angle needed to comply with ADR's. The only thing I'm not sure of is the size of the indicators, does anyone know if there is a minimum requirement as these look a little small.
I wouldn't run LED's though as you cant tell if they have blown as they dont affect the speed of the flasher.
Cheers
