I tried to post a couple times and I think I was trying too many MB's at a time so I will post a bunch to show what I want. In the mid 70's I rode my 750 K2 a lot at night. I wanted more tail light. I added a 1157 bulb in the housing. On the stop light part of the new bulb I installed a flasher. It all fit in the tail light housing. The video's are poor quality and do not really show how dramatic this is. Thanks, Dan
