I was sick of almost being hit by cars when trying to make simple turns around my neighborhood so I began to look for a solution, after a little bit of searching I found a good Instructable by adambowker98 but I saw it was a little older. 2012 to be exact and after looking it over I thought it could use some improvements so I decided that I was going to make my bike lights better. so that's exactly what I did.

Step 1: Drilling the Holes

First step one we're going to start with Taking apart the box and drilling the holes, what you first have to do is unscrew all four screws on the box. Then you have to lift the top of the box up and get your drill bit listed in the Parts section. Once you do that, you're going to find a hard surface. Anne. Something you can drill through. Then you're going to place the top of the box on the Surface and begin drilling. You're gonna wanna drill 10 equal holes in a triangle formation on each side. I used a stencil to help me which you can use. By tracing around The box. Then I measured about 1 to 1.5 centimeters in between each hole. Then you're going to take the drill bit and. Put it on a drill in. Make sure you drill directly down in, not on an angle Then you will have your perfect holes.

Step 2: Putting in the Leds

So then next what you're going to do is we're going to take 20LED holders and make sure they all fit in the holes perfectly, make sure it's a nice snug fit but not too tight or else you won't actually be able to get the leads in. Then what you're going to do is you're going to take an L Ed and find the positive side of each one, which is normally the longer side of the wire. Then I went that at a 90 degree angle, just a signified myself later that I knew that was going to be the positive wire. It helps later when your wiring. Next, after that, you're gonna put all of the leads and push firmly into the lead holder so that you can see the little nub of the actually poking out, and then you're going to put it into the hole with whatever formation you like. Then your box should look Like it works, but it doesn't yet 'cause we haven't done the wiring.

Step 3: Wiring

Now that you're going to do is we're going to take all the leds and the top of the box and you're going to flip it over. Then what you're going to do is you're going to begin by cutting 10 10-centimeter pieces of wire. Then you're going to strip about two centimeters on each side, which should leave you with a total of 6 centimeters covered in 4 centimeters uncovered. Then what you're going to do is you're going to Twist the frayed wires so that they become straight. After that, you can either solder them together or just twist them together. Then you're going to repeat this for both the positive and the negative side. So in total you should have 20 pieces of wire. I use different colours. I used green for positive and yellow for negative. Then what you're going to do is you're going to take another end of. Each of the 10-centimeter pieces of wire And hook them up to the positive side of the LD or the negative side, depending on which colour of wire you're using. Then your basic wiring should be done. Just kidding. You must do it another time for the other ten LEDs on the other side.

Step 4: Switch Wiring

Now for the actual switch wiring. The switch wiring is actually quite a bit less difficult, So what I ended up doing is I took black and red wires, red equaling positive and black equaling negative, and you're just going to hook those up by unscrewing the switch and coiling up in stripping part of the wire. And screwing it back in so that the Screw is holding the wire. You put the red on the middle and the black onto the side, so it creates A continuous current or loop. Then just for some extra style points I coiled up. The two wires together and wrapped them nicely just so it looked a little more aesthetic. Then what you're going to do is we're going to take all of that wiring that we've done before in the previous step an you're going to hook the positive. Green up to the positive, red and you're going to hook up the negative to the negative. Then all of your wiring should be completed.

Step 5: Putting Everthing Together.

Now for a last step, you just have to put everything together and mount it to your bike. I would suggest just using a normal bike light mount. You can also just drill some screws into the back of the box and route the wires out through another hole in the back of the box. That's what I did but. Then you can also use zip ties to secure the wires to the bikes actual frame. Be careful though, because once you use zip ties, you can't really take them off unless you use scissors, so your bike will be Essentially useless in the rain. You could also opt for some clips To hold the wiring in place, Then what you can do is you can either tape or use some other mounting, I just chose to put them on an secure them by hot glue. And that seemed to work out pretty good. Then for final little bit, you're just going to make sure that the turn signals work in all of your LEDs aren't burnt out. Another thing you could do Is secure leds if you have problems With them sliding out Or not staying firm. For this I would recommend super glue, but then once you've done all that and all your wiring is hooked up, you should have some working bike turn signals. Or if you don't want to do all that work, you can go on Amazon and get a very stylish set for $20.99.
