This is the LONG pin option. Long pins are the standard choice unless you are installing in hilts with shallow emitters (i.e. thin neck models), where you would want a short pin version. If you are not already using a chassis with a dedicated recess, you will likely need a PCB holder AND a Lens Cover (to better support the pins.

Kit comes un-assembled. You need to solder your own pins into the PCB.
