Sorry if I sound a little stunned, but what's the Tell Tale lamp?
Glad to hear you have it sorted.
I imagine why folks aren't running LEDs more prominently is that they haven't been fully tested in a rally environment? That and products are only coming to market now. I just noticed that Trail Tech is now offering some aux LED lights when looking over their site today. Hopefully as they become more mainstream the prices will come down too.
A friend of mine picked up one of these
to use as a supplemental night trail light instead of going upgraded stator and lamp route. He's very happy with the performance of the light, it kicks out a lot of bright white light, and you can't beat the price.
