Ive just bright white cointakers in the buildings, when you hear a bullet sound they go off, on top of the wharehouse ive used coloured leds and it looks awesome.......because the buildings always flash it can be over powering but adds a good effect.

I cut all the windows in my buildings out...... They were just round holes
Now they are square, I used a black permanent market around the edges of the windows to blend into the trimmed area. Then I added thin blue tinted plastic sheet between the inside of the buildings and the bulb......
I think it looks good, and it beats round drilled holes for windows

Post some pics, be intrested to see the look of it, nice thinking to give it that cop kind of feel

Here are some pics.
I used a knife to cut out the windows.
Then I just taped the plastic film on the inside.

looks good dont think the picture does it justice tho, have you just got a high bright led behind it.

checked my warehouse building and already has holes in it so I'm going to try different colours and see how it goes......thanks for the idea

hey you should post these pics on the Dirty Harry club on Pinside for other owners to try

I used a exacto knife----the blade is almost like a scalpel......surprisingly, I used no band-aids?
And used a black "Sharpy" permanent marker to blend in the window edges.
I just have the standard 906 bulb behind the film.
I think I layered the blue sheet/film to tone down the light.
I also cut cardboard out to fit under the buildings to stop white light from shooting out the bottom.
You cant see the cardboard... it fits inside the bottom.

more crazy stuff i did.......
-I added a laser pointer (red) to the gun, then tied it into the trigger with another switch inside the pistol shooter. When you pull the trigger just a little, the laser lights up and you pull all the way to fire the ball. Kinda like the laser pointer mod on STTNG.
-I added a mirror to the entire backboard. You can now see the hidden lanes in the mirror.
-I scanned the target decals and made new ones, then made extras and stuck them behind the backglass on the light board. The decals are placed directly behind the bullet holes in the backglass
You have to look directly through the hole to see it. This gives some depth to the backglass... you could put any sticker back there. Very simple.
-I also have some authentic "POLICE LINE DO NOT CROSS" tape I have been thinking of adding to the inside edges..... to many projects.

I havebpinball life led for the back flashers, they have 9 mini globes in them, pretty bright when flashing
