I've seen some pictures of our trucks with the yellow headlights installed. I'm guessing that they were used while in europe. I just think they look cool and want to find a set, but can't. I saw one set for sale on ebay about a month ago, but somebody snagged them from under me. that's the only set for sale I've ever seen. I'm sure they were used on m151's, m35's, etc in europe or whatever, but you never see them. If anyone knows where or why they were used, or knows where to find a set I'd appreciate any info. Thanks
