I'm looking for a guide that will show how to find and replace all the General Illumination lamps with LEDs on Twilight Zone.

It would also be nice with color suggestions för G.I. LEDs.

Sorry, I was not clear enough. I have already changed all the inserts LEDs (from underneath). I have also changed the flashers and the backbox lamps.

The big problem for me is the General Illumination lamps. There is no guide in the manual for them and it is not possible to test them one by one. Some of the are easy to spot (e.g. by the outlanes) but some are hidden in the upper playfield.

It would be a big help for me if someone could provide:
a) a guide showing where all of them are located
b) instructions how to reach some of the difficult ones
c) color advice (I generally prefer active color choices instead of "just" white)

Thanks!

Well, I did order Cointakers LED Kit (Super Upgrade) but no GI's were included. However, the instructions for the kit says that Playfield GI consists of 34 Cool Frosted 44s and 2 Warm Flex 555s (Street light). But there is no location guide for the GI's. It is also odd that the official manual doesn't have such a location guide.

I plan to use colored LEDs instead of the white ones. I have seen good looking color choices, like purple in the low playfield, red around the gumball machine and blue in the upper right part of the playfield.

If anybody has a location guide to share, please send me a PM.

If anybody has color advice (other than white), please post them here.

Thanks!

I have looked really close under the playfield and could only find 28 GI-positions.

I have not been able to find the GI in the Gumball Stack yet (mentioned by Coyote above).

Also I'm having trouble finding a way to replace the bulbs under the mini playfield (not GI's).

And how do you get to the bulbs in the "Start" and "Extra Ball"buttons?
