I have never seen it drawn like that but I'll throw out a guess that that oblique triangle on top is saying it's used for a turn indicator.. Only a guess.
I don't think that it is an LED, that looks like it would be something like a transistor, the triangle looks like the inversion indicator, and the arrow coming out would be a third pin.
Where is this image coming from?
Are there any connections?
An image of the actual LED would be good. I would not be assuming it is anything other than a regular (perhaps bright) LED since there's unlikely to be any weird devices on a motorbike.
The weirdest it could be is a side emitting surface mount LED.
A don't agree that it has 3 connections, but you could confirm this by looking at the board on which it is mounted.
i have seen something simliar but not that exact picture. the "N" with an arrow wasn't connected to the "O" of the diode though... in fact there was no "O" around it. this was in a kit for kids many years ago. and in that kit the symbol was a simple diode. hope that helps http://mypages.iit.edu/~smart/acadyear/circuits.htm just saw this in my travels, the second schematic shows the symbol I was talking about
