They're only diodes when all said and done Rod😉

44yr in electronics & I learned something from this discussion today. Hav never used the diode test function of my multimeter on anything but 1n4148 signal diodes. Didn't know you cud find out so much abt an LED that way.

Longest wire out of bulb is positive and if you get wires wrong way round LED won't light, if its wrong voltage it will either light ok or light Dimly or just burn out quick👍👍

In lieu of heatshrink tubing you can use a brush-on insulating coating which is sold for automotive & marine use & often used to dip tool handles to insulate them. I get mine at PRINCESS AUTO. The lid includes a brush immersed in the stuff.
Don't apply a battery directly to the LED, it will destroy it. You need a current-limiting resistor, occasionally referred to as a ballast resistor, I wud suggest a minimum of 68 Ohms or 100 Ohms. That's for a quick test. For a permanent installation you will want to select the resistor value to give you the desired brightness.
Red LEDs require the least voltage, other colours require more, & a white LED needs a bit over 4V to "ignite".

Simy put, if both wires are same colour, if they don't work one direction, reverse your wires.
Some LEDs have one wire longer than the other.- longer lead is often the pos.
The wires can usually be stripped with a thumbnail or small blade.
I solder the leads, then cover with small heat shrink tubing.
