For all of you that own a Bally Star Trek here is a great and simple mod that makes a big difference to the backglass artwork. Have you noticed that the blue planet on the right side of the backglass is not illuminated? It is a very predominant artwork feature that simply gets lost. I always wondered why there wasn't a bulb put in that location but when I saw the original backglass artwork there was no planet there. Guess when they changed to the movie version backglass with the extra planet and Klingon cruisers they never changed the position of the illumination bulbs to highlight the new added graphic features. I figured that a blue bulb in there would really make that planet pop!
So for this easy mod I measured the location and simply drilled a 1/2 inch hole through the plywood panel that holds the bulbs. I then added another socket and installed a Cointaker blue 170 LED. Now that wonderful planet really pops out!!
For the rest of the backglass I have Cointaker 170 warm whites in all of the sockets except for 3 cool whites behind the Enterprise and 10 warm white frosted from pinballbulbs.com behind the "Star Trek" up on top. The Cointakers where not bright enough to make "Star Trek" stand out. Also blue 170's in hi score and ball in play, reds in tilt and match, oranges in game over, and a slow color changer behind the "energy ball".
Below are before and after pics in darkness and then in daylight room lighting.
Hope you all like it! Thanks!
