Howdy folks. My detached garage is off limits for a few days while some vinyl plank flooring is being installed, so I'm unable to work in my train room for the duration. I decided to use the time to repaint an Atlas O Trainman (TMCC) that I obtained a couple of years ago on eBay. I'm not a fan of the demonstrator paint scheme, but got a very good deal on a virtually new locomotive. Soon it will have the ubiquitous grimy appearance of a Pennsy RS-11, as inspired by the work of Norm Charbonneau (if only I could achieve his weathering skills). 

While I'm at it, I'd like to replace the amber headlight bulbs with clear ones. Since the tech engineering of this locomotive is more than a decade old, I'm hoping there is an "easy" option for new bulbs. For example, each bulb has its own tiny circuit board (see attached pic). Are they integrated with the fwd/rev signal in some way, or with the option to turn the lights on/off? (I would think that those outputs would be on one of the primary circuit boards, but what do I know?)

Looking for recommendations from some of you who have gone down this path already. Thanks in advance!

The pennsy had about a dozen RSD7 and RSD15 locos.   I can't remember if exactly 6 apiece or not.   There maybe have been 7 and 6.    They are much much bigger than an Rs11 or RSD12.    They are longer and I think taller.     I can look up the numbers for you if you like.    If it were me, I would number and detail it for one of those rather than an RS11.   

If those lighs are the same as the Weaver RS11, they would be 3 MM leds.    Just repalce in kind.    The ones on  your loco may have resistors built-in or attached.    If they do,  you need to add a 1000 ohm resister to  your replacement.    If the ones in loco have the resistors separate on the board or wire, just replace the LED.   Remember LEDs are current specific.    You have to get the plus and minus side of the input correct to get it to  light.    So test before you solder to figure out which wire goes where.    And LED is a light emitting diode and works just like other diodes in only letting current flow one direction.
