I have two Haibikes, both 2017 models, a full nine 6.5 and a all mountain 5.0, both powered by yamaha. On the bottom of the switch panel near the left grip there is a port that appears to allow something to plug in.... Wondering what is supposed to plug into that port and if there is a way to plug in a very bright LED light so I can do some night rides. I currently have a few of these type of lights and nothing wrong with them other than I have to charge a separate battery and strap the battery to the bike somewhere. Plus those batteries don't seem to last as long as I would like. https://www.amazon.com/gp/product/B...beb-4819111bef9a&pf_rd_r=ANWETWM2ES2H5M35V6Z6
