Cant say for sure, but I imagine it would be a tiny soldered in LED or similar rather than a bulb? Only way to find out it start taking it apart.

That is definately an LED. They last a lifetime literally, unless a reverse voltage has been applied to them.

Generally they need a resistor in the negative lead to reduce the current, however they can be used without a resistor if the voltage is no more than three(3) volts.
By any chance did you insert the battery the wrong way round?

You can get replacements from Maplins quite cheaply, they come in different diameters, 3/5/8 mm for example.

The negative lead is usually the shortest lead.

to the above point, most leds have a flat side, this is also a i sign of the negative

The scope cam in a trade so i i'm guessing the LED blew before it got to me. Will try a replacement thanks
