I found M6 MAGNUMLIGHT sold in local flee market a few days ago. The seller says they did only some check if it worked, and it has been kept almost unused. The condition is pretty well as long as I see the photo. The price is about USD 250 including original xenon bulbs. I wonder if I should buy it or bye it. I think it might be a good replacement parts for my M6 in case, but mine is M6 GUARDIAN. I'm not sure MAGNUMLIGHT and GUARDIAN are completely LEGO compatible. I could take the risk if it were USD 150...
