    Idea! MagicShine MJ-818 Tail Light - Custom Threaded Rack Mount

    I recently bought a MagicShine MJ-818 for a commuter bike I'm building for my wife. I didn't like the rubber band mount and wanted a more solid way to mount it to the back of a Topeak Explorer rear rack so I did a little customizing. I'm adding these pictures and details here to help out anyone in the same situation.

    First you have to use a phillips screw driver to remove the concave rubber band mount from the back of the light. Next you have to take some scissors or side-cutters and trim the back of the rubber grommet to be able to push it into the light and keep out some water. For a little extra assurance I added some silicone around the cable and grommet to further waterproof it.

    Next you need to make a trip to the hardware store and grab these items:
    M4 x 25mm hex head bolt
    2 M4 Fender Washers
    2 M4 Lock-washers
    2 M4 Nuts

    I put the hex head bolt through the existing hole in the back of the rear rack and tightened up the first nut. Then I used some loc-tite and threaded the MJ-818 onto the bolt. I then tightened up the second nut and lock washer against the light once I had it oriented the way I wanted.

    Overall the project seems like a success. It feels really solid and looks nice.

    Oops. I forgot to attach pics

    Here are the pics. I have recently added one of the Y-adapters and zip tied an extension cable most of the way up toward the front of the top tube. It lets me run a front and rear Magicshine from the single battery.
