I am trying to install a battery Voltage Warning LED in the dash of my boat. The LED that came with the kit is a 5mm led and the plastic mount for it is far to short to install without glueing in an over 1/2" thick fiberglass dashboard. I am looking for something longer that I can use to mount the LED with an attaching nut from behind. I have attached two pictures, one show black plastic led mounting that is to short for the dash and the other showing the type (except longer threaded portion) that I am looking for. So far I have found nothing. Any ideas?
