Weaver Hiawatha Atlantic

[tbwilson4]

Any suggestions on repairing/replacing lamps in front marker lights on Weaver Hiawatha Atlantic?  Had a minor derailment, but instead of scrolling voltage down to rerail front trucks, voltage was instead pushed to 22 volts by some idiot engineer, just long enough for both front marker lights to go out for good. Does this engine require a specific bulb or LED? It looks as though the smoke assembly needs to be removed to gain access to the forward lamp area,and I didnt want to try this unless I had the correct replacement bulbs in hand. Was hoping to avoid sending unit back to Weaver-engine is just too fun to run! Tim Wilson
