Wow... that was fast. I got a call Wednesday afternoon that all the parts had been anodized, and I was able to pick them up this morning. To say that these guys are good would be a major understatement. Great attention to detail. Beautiful finish quality with no bleeding anywhere and no damage to any of the parts AND all at a reasonable price. They even individually re-packed every piece in it's own bag exactly the way that I handed the bare parts to them on Tuesday. So thanks again to Pam and Ricki and crew at Advanced Technical Finishing (ATF) for such great service. If you ever need any parts plated, I highly recommend you give them a call!

Power wire entry O-ring bonded to housing. This is a VERY tricky technique. Can only clean the residual adhesive after it cures for 24 hours.

Went ahead and completed one taillight for a little 7.4V rundown testing... This one is coming your way Ed. The new light as show here, weighs in at exactly 100 grams.
Here's a few pics of the FIRST COMPLETED TAILLIGHT from build 3:

Step 6. is actually a lot more tedious that it sounds. The power wires have to be stripped AFTER the wire is inserted into the housing. Then, in order to prepare the wires for insertion into the power supply, they have to be carefully trimmed and tinned. Lastly, I add some high-temp heat shrink over the Red/Black insulation since it is not high temp and will melt during the soldering process. This pic shows the power wires but also shows the lid o-ring and internal jumper wire.

From Step 12.... the extender bars turned out beautiful. Nice and clean. Good lines all around. NICE job Robert. This is the KEY piece to making the lights work with the Cateye mounting system.
