Is it ok to put LEDS in sys 1 gottlieb game  1...playfield ?
                                                               2....backglass ?
I put some in a EM Abracadabra playfield and they flicker?plulse or something..but can put up with it!
Mainly need to know I won't damage any thing in the sys 1 ?
cheers

I put them in mine, no probs.
I used the cointaker ones and they don't flicker at all, I have never used the RTBB ones but I am sure they would be just as good.
Like Nino says, don't use the cheap Chinese or ebay ones they are complete rubbish.
