I've added a luggage case to my Suzuki DL650. The case come with a built in added light kit. The case two wire system taps into the existing bikes brake light wires.I attach the wires as directed, and I've tried both options possible with the wires. The results remain the same. Light kit has power (lights up) But when the brake is applied the new light kit goes out instead of getting brighter.Again this result is the same regardless of which wire combo I use.Thanks for any help!
you should have three wires going to your orig brake light if not then it is using the subframe as a ground try grounding one of the case wires to the frame and put one of the wires to one of the light wires
make sure its grounded good those work on a grounded circuit if its not got good ground to it the light will go out when you hit the brake on it,good luck.
