Keystone 5.9mm Diameter LED Holder for use with 3 mm (T-1) LED

The "snap-in" LED holders, from Keystone, are designed to be used with 3mm (T-1) or 5mm (T-1 3/4) through hole LEDs. The holders can be easily placed into the front panel with the LED snapping into the back of the holder. The holder then keeps the LED securely in place.
The 8309 and 8310 LED bezels are ideal for general purpose indicator applications. Their black face improves the appearance of the LED and offers a high contrast with the LED light.
