This step seems long but really you are only drilling holes in your handlebars and endcaps.



Removing Handlebars:

Take your handlebars off your bike by undoing the allen screw(s) holding them in place at the top of the fork. There are many possibly ways they could be attached so I'll let you figure that out. Next, remove your handlebar grips/tape and brakes. After you have the bar completely off and bare, remove the end caps by prying with a screw driver. Next, use a marker and plot where you want to make holes for the LEDs and buttons. I placed the buttons 4 inches on either side of the center of the handlebars and the LEDs in the end caps.



Drilling Endcaps:

Now you will need to find two drill bits. One that is the size of the LED "bulb" and another the size of the button part of your pushbutton. First take your end caps and use a clamp to hold them in place. Fix your LED drill bit into your drill and make a hole clean through the center. Test to see if your LED is able to protrude from the outside end so will be visible when mounted. If not widen the hole by wiggling the drill bit or trying a larger bit. Repeat for the other LED.



Drilling Handlebars:

I recommend putting the bars in a vice. On the spots you've marked on your handlebar, use a hammer to pound a nail to make a small mark that the drill bit can grab. Then fix your button drill bit and drill each of the holes. You will also need to make another hole on the back part of the handlebar for each hole you just drilled (so you will have a hole going completely through both sides of the bar). This allows you to push from the back of the button and stick something in to keep the button pressed up against the handlebar so it can be clicked without falling back into the bar. I recommend doing 4 holes in the same spot (2 holes going completely through both sides of the bar). This is because it is extremely difficult to twist a button so it can be pushed through the holes you have drilled.



Finishing Touches:

Use a metal file to smooth the holes drilled in your handlebars. If you have a de-burring tool or a small file, then use those to smooth the inside of the holes as well.
