Can't see much on the parts diagram but just a thought if you have a Lokprogrammer check to see if the headlight box "On" is ticked in forward direction. Failing that if the light was working before the conversion I can only mention to recheck your wiring carefully. The low-mounted headlight on the front pilot is LED powered and authentically fades in/out by pressing F0. Below the headlight is a stand-up UP shield with 4014 on it. https://static.maerklin....7d247dff5d1434541915.pdf[/url]

Chances are, you have a broken wire because I never saw a faulty LED of this generation. The lower illumination is made by a lower PCB number 67 on the exploded view referenced 216931 Cheers Jeab
