Will transfer the How to soon, but i've put the picture up so you can see how to and might not need the description off the old forum.

How to:

When i first got my traintronics signal i was slightly disapointed by the light bleed, at the time I had to accept it.

But the other day I decided to have a fiddle (technical word) around with my signal, it turns out a simple 5 min job will fix the problem.

Firstly you have to prise gently the back pannel off the back of the signal, you will then be faced with the back of the circuit board which with some gentle pressure on the lights from the front will pop it out; now i will be honest i don't know how they work but i think they are very small led's. The problem is that it is all a molded plastic part that bleeds light.

So the solution is to simply paint the plastic that you don't need in ideally black as it will stop any light bleeding through, just leave the end 'bumps' clear to allow the light to escape. Put it back together and job done

I have only tested it once but the results are much better with no light bleed what so ever, so if you want a cheaper alternative to scratchbuiling but don't want the quality issues then it is a simple solution.

Hope this helps someone,

Thanks,

Joe
