I recently bought a LED replacement for the #93 taillight my 30 year-old bedside Tensor lamp uses. I like it. I have not found a good source for #93's in years and have been paying way too much at auto parts stores..
The added fun part is I have a fan; and the LED strobes such that the fan almost freezes. Obviously the fan is not a synchronous motor and has slip, so it seems to drift. But it still is an interesting side effect.
