Summarize:

Look to drill somewhere on the back of the bottle near the bottom. Consider applying a piece of masking tape to the spot you plan to drill. The tape will help keep the drill from slipping and help to prevent the glass bottle from splintering near the drill site. Roll a piece of clay into a rope approximately 4 inches long and about inch in width. Then connect the ends of the clay to form a circle. This circle will serve as a little water reservoir to lubricate the drilling hole and glass as you drill. Surround the area you decided to drill with the clay, and press it into the bottle to seal the reservoir. You might also consider making a pocket (a thick pancake shape) of plumber's clay, and drilling through the clay you drill. If you decide to drill this way, you must slowly pour water onto the bottle as you drill your hole so the drill doesn't over heat the bottle and cause it to splinter and crack. Before you start drilling, put on your protective gloves and glasses. It's also advisable to wear long sleeve shirts when drilling glass. Use a hand drill with a inch diamond bit, or glass and tile bit, to drill your hole. Place the bottle onto the jig so it stays put while you drill the hole. Hold the drill vertically straight, and start the drill. Lower the drill until it just barely comes in contact with the surface of the bottle. As you start cutting the glass, glass dust will dust up the water reservoir, making it cloudy. Continue drilling, pushing down ever so slight onto the drill. Eventually (after about 20 or 30 seconds), the water in the reservoir will start to leak and drip into the inside of the bottle. This means that you are almost completely broken through the glass. Once you have drilled through the bottle, pull the drill out from the hole and turn off the drill.. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/a\/a8\/Make-Wine-Bottle-Accent-Lights-Step-10-Version-3.jpg\/v4-459px-Make-Wine-Bottle-Accent-Lights-Step-10-Version-3.jpg","bigUrl":"\/images\/thumb\/a\/a8\/Make-Wine-Bottle-Accent-Lights-Step-10-Version-3.jpg\/aid3659957-v4-728px-Make-Wine-Bottle-Accent-Lights-Step-10-Version-3.jpg","smallWidth":460,"smallHeight":306,"bigWidth":"728","bigHeight":"485","licensing":"<div class="mw-parser-output"><p>License: <a rel="nofollow" class="external text" href="https:\/\/en.wikipedia.org\/wiki\/Fair_use">Fair Use<\/a> (screenshot)<br>
<\/p><\/div>"} It is very important that you don't force the drill through the glass. Too much downward pressure could make the bottle to crack. Look around the drill site for fractures in the bottle. If you see any cracks, you might want to discard the bottle, as it will be very fragile and potentially dangerous. Remove the clay lubricant reservoir and empty the contents of the bottle into the garbage. If the drilled out glass disc isn't in the bottle, it's probably stuck in the drill bit. If that's the case, try to pry it out with a paperclip edge. Use sandpaper to file down the sharp edges created by drilling the hole into the bottle. Then rinse the bottle with water to wash out any glass bits, and allow the bottle to dry again. 150 grit paper will sufficiently smooth out the rough edges of the hole. Remove the decoration lights from the box, and pull the lights taut so they can lay straight. Check to make sure the string of lights work by plugging them into an outlet. If the lights light up and are working correctly, insert the first bulb on the string in through the hole that you drilled out. Continue inserting the lights one by one, being sure to keep the outlet plug remaining outside the bottle. To help fit the light bulbs through the hole more easily, push the light against the cord, and push both through at the same time. Be careful not to cut the lights cord on the edges of the hole. You might have to turn the bottle upside down in order to move the lights inside the bottom "up" to make room for the rest of the lights entering through the base of the bottle. Once you've finished feeding the lights into the bottle, wrap the stopper around the remaining strand hanging from the outside of the bottle, and insert the stopper into the hole. The stopper will protect the cord from being cut by the raw glass edges of the hole and keep the lights inside the bottle.
Mark your drilling spot on the bottle. Make a lubricating water reservoir. Drill the hole in the bottle. Check your drilling work. Sand the drilled hole. Insert the lights into the bottle. Secure the lights with a stopper. Finished!
