I just reduced the 60 mA of my GPS-18 to 40 mA
by clipping out the LED in the cigarette lighter plug.

Thats a power saving of 33% and is significant
in our ocean going APRS buoy we will be deploying
soon.  I was amazed. (now I hope that the LED
is not somehow otherwise involved in the circuit.
We'll see.
