Hi Guys
Has anyone cut off the LEDs from the control unit (of the Gretz heated pitot tube product) and mounted it remotely, and then mounted the LEDs on their own wires to the panel - if so: how did you get on, any problems ???
Regards

I’m confused on what you are attempting to accomplish.
The LEDs aren’t on the control unit, they are on a separate circuit board. This allows them to be remotely mounted. I would leave them on the board to add more strength to the mounting point for the LEDS. There is nothing magical about that circuit other than a resistor and LED. You should be able to reverse engineer the traces by looking at the board. Or you could just give Andrew at Angus Aviation a call. Just remember that he’s fourteen hours ahead of us.

Yes: I meant the separate circuit board: it does seem to be a lot of weight (relatively) to hang on the three LEDs

John,
I eliminated the Gretz LED's and mounting board altogether. Replaced them with 3 new LED's epoxied from the back of my panel, and wired without the mounting board. Works fine.

Just what I had in mind: but using some chrome bezels (which are available
for LEDs) for easy replacement of the LEDs if needed
