Lucas replica turn signal with a 125mm long stem, approximately 10mm in diameter, and non-metric thread. This is as close as it gets to original equipment Lucas turn signals that would have been used on Ambassador or Eldorado back in the day. Note: These stems are longer than the originals. In order to better replicate the original appearance, the stem should be shortened so that it all but disappears when mounted on the motorcycle.
