Well, lets go see what Miniatronics has available:
3 mm .118" that's a wee bit under 1/8 inch.
5 mm .197" that's a wee bit over 3/16 inch.
That 5 mm one is going to be similar in size to the Athearn bulb that you are
replacing, however, depending on what you do, and how you do it, the correct
is going to be determined by your personal preference. Both will work equally
In something like an F unit, I would probably favor the 5 mm one.
In a Geep, I would probably opt for the 3 mm size.
If you've never done anything like this before, don't be shy and undecided. Go
and take the plunge. Once you do it the first time you will see how easy it is.
can get LEDs cheaper than Miniatronics sells them, but the advantage of buying
Miniatronics LEDs is that all the guesswork has been removed from the process.
know what the LED will look like, and you know that the resistor is the correct
value. So, unless electronics and mathematics is your hobby, Miniatronics is
thanks again Froggy :)
I hooked up an old athearn GP 35 tonight with a MRC decoder and it
I dont like the Brightness of the Athearn head light so i'll be looking
for the led's to install tomorrow.
I'm running the new Prodigy advance and it seems pretty simple compared
to the upper end DCC systems.
it was simple to program the 4 digit address (locomotive number).
Thanks again :)
Rather than bothering with a LED, why not just put a resistor in series with
the light bulb? Decreasing the brightness of the bulb will lead to a much
longer life for the bulb in addition to gettign that proper yellow glow of a
