I bought a Yana Shiki HID kits H4 with HI/LO for my 2005 Harley softail Deluxe. When I first installed the unit I noticed that the HI beam did not. Later I noticed that while having this unit on the bike. I noticed that it kept causing my right side lights front and rear to malfuction on my bike like the security would come on and off. It also caused the right rear tail light to come on and off when ever I turned on the ignition switch. I have spoken to several REP from Yana Shiki and they could not figure out what was wrong with the kit. So I took the unit off of my bike and return it back to Motosport. Now all of my lightings on my bike is back to normal again.
