Ok this is my first review but I will try to make sure I include everything that I can about this product.So First off I want to make sure that if you are interested in this product that you understand that it is not a replacement taillight for your bike in the plug and play sense but a upgraded replacement for your taillight LED module inside the taillight housing itself.You will need tools to complete the installation.You will need a flat tip screwdriverA dremel rotary tool with cutting wheelsome superglue or other adhesive (I used clear silicone: worked great)Wire cuttersWire Strippers ( Not needed unless your wires are thicker than anticipated) I 'll Get into this latera cross tip screwdriver (Phillips screwdriver)and a set of pliers (needle nose is what is recommended but regular work just fine.)Ok so now that we have gotten the tools out of the way I do want toad that even though this might sound like a bit more than you were hoping for the installation is pretty easy and can be done in about 30 min depending on the adhesive you use.The website from the company doesn't ever really explain that you will have to do any of this so When I bought it and was deliver I was a little hesitant about the installation ( I didn't want to mess anything up and be forced to buy a new taillight or be stuck not being able to ride until I got the light replaced.Bottom line is if you have these tools already and have used them in the past for something then you have the ability to do it!InstallationAll in all installation is pretty easy. The instructions that it comes with are very clear and easy to understand. I didn't have nay problem with trying to figure out what they were talking about at any time. The kit comes with wire splicing pieces for the taillight itself and wire spicing pieces to wire the turn signals into the taillight in addition to the existing ones or to replace the existing ones. I went with replace the original ones (it was half the reason that I bought the unit in the first place. But I can see the want of having the extra turn signals for added visibility to other vehicles on the road.The hardest part about the entire installation was trying to figure out if I had cut into the taillight piece far enough. The instructions tell you to cut down about half way then use the flat tip screwdriver in the groove that you cut to pry the two pieces apart using a twisting motion on the screwdriver. they do warn not to cut to far into it so that you still have a seem around the light housing to be able to attach it back on easily after your ready to. This can be tricky and I did end up chipping a couple of small pieces off of the edge of the clear part of the housing. So I cut in deeper and tried again. There is a bit of trial and error to it but nothing to hard. If you think that you have cut in far enough and you have only made 3-4 passes along the edge with the dremel then you might want to think about doing it another pass or two before you try to remove the two pieces.This was the hardest part of the whole thing and the most time consuming.WiringWiring is easy just follow the directions it walks you through step by step and tells you even how to use the three splicers that are included for the taillight. They do warn that on some models of bikes that the color combination on the bike itself might be different but mine wasn't and matched up perfectly.A note on the splicing. when you cut the wires where it tells you to you might want to make sure that the cut area is fairly crisp and try to squeeze back as round as possible. You might find that if you don't it could be a bit difficult to get the wire all the way in the splicer. Also the splicers have a little bit of glue inside them that is released once you squeeze the orange piece down this is to help ensure that the wires do not ease their way back out.Once you have gotten the wires attached to the taillight connecter and attached the new LED board to the grey piece of the housing you'll want to plug it into the bike to make sure that all the wiring for the taillight is done right. and that the wires are not rubbing or being pinched anywhere in the housing.After the light has been checked unplug it and follow the rest of the instructions for the turn signals.Again this is straight forward with witch wire is for left and for right and easy to understand.Reassembly of the taillight.Putting it all back to together is pretty easy. just put a bead of adhesive around the remaining edge of grey piece of the taillight and then put the clear piece back on minus the other clear piece that was removed in the instructions. ( The instructions tell you what pieces you can get rid of after you have removed them during that step. Pretty helpful to know that)I decided to use clear silicone since it was waterproof and it gave me a long enough setup time to make sure that it was in the correct position. Once I had the two pieces back together I put a clamp on to hold them together while the silicone set and put a thicker bead around the space that I had cut away. probably added about 30 min to the total time that it took to do the whole install with the set time of the silicone.Finished.That's it once the glue is set all you have to do is put it back on the bike and enjoy your new taillight. This thing is bright to you have over double the amount of LEDS in there than before and your turn signals are bigger and brighter now as well.I hope this was helpful and I hope this answers your questions about it.
