I think I read someone say a couple hours while taking their time.

Installation was fairly quick but while I was doing it I decided to change to white rubbers so my time would be high but I think I spent about 1hour total.

Thanks, I'm going to do the same thing while I'm at it, white rubbers.....

Yup...I usually change them to white within a week. Sounds like its easy Pinballer22 if you got it done that fast.

White for the Munchkinland pf? I think that works better. Purple is good for the castle, but Dorothy's house did need more neutral illumination.

BTW, install time was a little over an hour for me, taking my time. I took the left ramp off for the upper spots; easier to remove the spots from the top of the post though, and then install the post and replace the spots!

This mod definitely makes the game more playable. Until they add a software setting to dim the inserts more, you need this to see the playfield and ball near the flippers!

Great Kit! Really does the trick, took about 1hr.

Did anybody here swap out bulb colors on this kit? And if so, what combinations did you use and where? (Pictures would be great, too!)

mine arrives today, I'll take some before/after pics

Took me a little over two hours to install being extra cautious. Probably 45 minutes of that time was trying to decide whether to stick the back light strip to the wood or underside of plastic glass sleeve.(I chose Wood) I also removed left ramp and removed spotlights to tighten down post then re-attaching. Not enough clearance to spin the post down with spot lights on for upper left spotlight by spinner. If I had to install another kit it would take 30 mins tops. Since installing the kit I only play in the dark now. Game lighting looks so much better now. This kit is a must have.

Had a problem with the left door too. It gets bashed a lot and the door shaft is held to the motor by two allen wrench style screws. Mine vibrated loose to where the pole slid down ever so slightly(maybe 2 milimeters) where the flange on the post no longer could clear the locking mech when that coil lifts up and down. Had to pull the witch playfield and lift the door shaft up while re-tightening the screws. There isn't much clearance there. The flange could stand to be a bit smaller to allow for greater margin of error. Its all good though.

Since this thread is a little old, thought I would post the URL where to buy these:

Bump. Gosh, I hope I get a discount on a set.
LOL
I need to wait until after the holidays before I can order mine. Money is too tight right now, but man, does this machine need it!

I did buy a WOZ to day and the GI is one thing i'm worried about.

Can you show before and after on youtube? And why not add a installation manual on Youtube, i'm a bit worried buying this and not sure i will be able to install it...

Thanks!

Sorry but its very hard to photo LEDs in the dark and video recording is going to be even worse. There are before and after pictures and a very long and detailed pictured installation set at pinball bulbs web site. You might want to look at that material and see what you think.

There's no bigger idiot than me, and I was able to do it fine with their awesome instructions. And it looks great on the machine. Buy with confidence!
