LED 1 x 5mm red stackable for bargraph with long (normal length) leads. Unique design allowing for custom made bargraph displays, typical use in mixing desks VU meters /. graphic display models. These LEDs interlock along the long axis making a seamless infinite length display possible. Or can be stacked normally. (please see example) each face 5 x 1mm nom. (4.9 x 0.96 actual) stepped at 3.6mm down from top face to 3.5mm x 5.4mm interlocking profile ( please see drawing) (all dimensions approximated) but would suggest that a milled slot in a front panel of 1mm will allow for a neat fit. If the panel was 3.5 mm thick itself then these would fit flush due to the step. This step also allows for easy palcement and fixing ( silicon glue /glue gun). lead length: to 24 / 25mm mm on 2.5mm pitch
