Well,

I completed the alien scan mod by equipping the containment tube with the color changing LED per several requests from Pinsiders .Link to video of it in action posted below.

I also added another alien to the playfeild near the upkick return from the alien head lock hole, as seen in the 2 photos with red flasher on in the background, and another shot of it with the (blue) lit up ship bearing down on it from behind.
Last an ID4 alien topper perched on the top.

Very nice, my containment tube is ordered []
That was just what i was looking for to complete the machine.

JoachimR,

FYI:
1.I had to cut the tube down about 1/2" to clear glass.
2.Heated a pan and melted the base of the tube to the appropriate angle for it to sit level on the playfield plastic.
3.I used this lamp socket in the containment tube.(remove shade)

4. I filed the original hole in the base (where push button was) large enough to insert the lamp socket (hot glued in place)
5. Made the hole in the center of the base larger for more bulb light to exit.
6. Made a reflective (bottom)cover for the base (below the bulb) with alum.foil onto duct tape to reflect all of the light upwards in to the tube. (hot glued to base bottom)
6.Used the lamps existing mounting bracket (with hole in it) to secure the entire thing to the playfield plastic with existing screw.
7. Wired it in with the existing alien head spot light.

Here is a link to a video of the mod in action:

Thanks!
I hope to post videos of all of my machines in action on Youtube. I know I searched there a lot while I was Pin shopping, and there just isn't enough videos of different machines in action.

Chris Bucci's are the best.
