Reddit mentions of Tusk Hydraulic Brake Switch Nissin Brakes

I did this to my 2001 E last year. I used this kit: https://www.amazon.com/gp/product/B00RNI4QIE/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 It was easy wires to the battery and wires to the head light everything else is plug and play. The DRZ already has a high low beam bulb you just have to play with the three wires coming out of the headlight assembly until you figure which is high, low and ground. Other than that, it is tucking wires along the existing harness until you get to the rear. Remove the stock LED taillight and drill some holes to hold on the new light and blinkers. Disclaimer: you will drill holes in the tail fender and probably you headlight housing. I would also buy an additional tusk brake switch: https://www.amazon.com/gp/product/B0039ZTQEO/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 to replace the bolt on your front brake lever. This will light up your brake light whether you use the front or back brake. Also this kit requires that you turn it on/off manually (easy switch on the handle bars), but you could wire it in to the ignition I just never did. Bottom line is that it is very easy. took me about 3 beers, that's one evening in normal time.
