Yeah, I should probably be using a heat sink but so far so good. With the extra resister in there the temp of the LM is down to 60ish deg C.

On a side note, anybody know how I can wire up 3 watt luxeons? I want to make some LED turn signals that only need 1 LED for each side and I think the 3 watt ones will do.

If you have to ask about a SAS, you're not ready for it.
