Well, it has a heatsink on its base. Or is that just its base?

And I hooked it up to switch on with the key.

When properly installed, I think I'll also add an additional switch, so I can optionally leave it off during day use (if I'm going to solar support/recharge the 12v, for example).

Anyway, it didn't get smoking hot, just warm. Mind you, it's 4C / 39F ambient here at the moment. And it was a short trip (as are all ForkenSwift trips) - around 5 km per leg.

It only "supports" the 12v battery when the headlights are on - doesn't keep the charge up. Headlights on, the voltage seemed to sit stable around 11.5v. (That's from a starting point of about 12.45v - a bit low.) Lights off, it will charge, however.

We have a second module I could add. 200w should be ample.

Pretty civilized to have night time driving as an option though, where I'm not wondering if I'm going to make it home before the lights go out!
