For the guys having the new 765's in their hands, I'd WAIT a bit for the dust to settle before swapping out the MARS light on their Loco. In other words Do Not try to Remove the Pre-Installed LED Bulb from the Smoke-box that arrived in your Loco. It probably won't come out with out breaking. I recommend making up a new harness with connector and LED to put in the Mars light Smoke-box should you choose to install it on your 765.
I don't know. I thought you would know. Maybe Rich will let us know. But either way I like it better with just the single headlight.
To me the directions are not real clear on the swap. That's just me. The bulb might have been poorly attached. But for a few bucks I can get the new part and put it all back together as was and that will be the end of it.
White Mars half the time, they said...sort of...
