That's the great part! Look closely at the other picture of the light & you can see the bracket which came on the light. There is a Phillips screw attaching it on each side which can be loosened enough to hold the light while still allowing you to adjustthe beam up & down. Like I said, the bracket is just attached to my bar with a couple of hose clamps: just happened to have stainless clamps in my tool box. This light setup works like a Soviet block weapon, crude but effective! The blue bottle was mentioned by somebody else on this forum, its a "dry" type lube that contains teflon, available from Lowe's at a very reasonable(cheap, cheap) price. I've been using it for chain lube & seems to work fine, comes out liquid then evaporates leaving a dry lube behind that doesn't seem to pickup dirt as quickly as other lubes I've tried & also doesn't wash off right away in the rain. Look for it by their tool section where they have a rack full of various lubricants & grease. Don
