But LED isn't a word, it's an abbreviation for Light Emitting Diode. It should really have three full-stops, one after each letter.That's basically right but as ever in English, there are exceptions. A good one is the word LED (as in light bulbs).
Using the above rule, you'd say "a LED" but that doesn't sound right. "An LED" is much better.
So it seems to depend on the shape you're making with your mouth/tongue with the word after the "a" or "an", which is strange because you then have to pre-empt the word.
If you were to pronounce LED as the word "led" it would have an "a" before it, as in "a lead weight". As an abbreviation, it is pronounced "el ee dee", and so needs an "an" before the "el" in the same way as before elephant.
