The bulbs shipped by Walthers in the DC locomotive become far to hot running with DCC! The roof of one engine is damaged after 30 minutes switching. The head light was not dimmed. I dimmed the head light on another engine down to 150 out of 255 and the roof became still very hot. I assume they are specified for 12V only and that might be already critical.
I will rework the engines to LED. A good opportunity to add the rear light too.
