Thank you for your reply Jonathan about the Spectrum K4 Pacific. I don't think that you are familiar with that particular locomotive.The headlight is not mounted on the middle of the boiler front. It is mounted at the very top of the boiler and sits on a bracket. From the diagram that came with the loco the bracket pulls out of the boiler. I have tried pulling on the bracket but it doesn't budge and I am afraid of pulling too hard and causing breakage. Hopefully someone will come to my rescue. Thank you, Bob

I have a Spectrum HO Scale Pennsy K4 Pacific  cab # 54754 that dates back to the 90's  It runs perfectly but needs a new headlight.  I believe that a special bulb was used.   The stock no. was 6081 and it was a 1.5v bulb. From the diagram that came with the loco, it looks like the light housing just sticks jnto the front of the boiler. I have tried pulling it straight out but to no avail. I'm afraid to pull too hard for fear of causing breakage. Can anyone please help me? Also can another type of bulb be used in the light housing? The original burns out very easily if the voltage is turned up. Thank you for any help that can be given to me. My e-mail address is:   bobv.2@verizon.net
