On the left is my V11 Lemans headlight with inexpensive H4 LED underneath it. On the right is a 7" round sealed LED lamp assembly.
I attempted to replace the original equipment H4 headlight bulb with an LED H4, the inexpensive LED H4 lasted 2-3 months. My 2nd attempt to move to an LED involved buying a 7" round "Jeep" style LED headlight assembly. Unfortunately I now discovered that the 7" Jeep thing will not install. Apparently, the OEM headlight/reflector assembly have the tabs molded into it that allows the assembly to be secured into the HDL bucket, a tab on top that fits into HDL bucket & a tab on the bottom that contains a speed nut for a securement screw, in other words the OEM assembly is NOT secured into the bucket by the headlight bezel/trim ring. The trim ring "snaps" onto the headlight/reflector assembly. So, I have no easy way to install the Jeep thing unless I can somehow find a trim ring that will fit onto the Jeep HDL, has a tab that fits the HDL bucket on top and a tab on the bottom to allow a screw securement. Oh well, live and learn. At this point I'm inclined to try another budget H4 LED, I've become very good at fairing r & r. Plus, I installed an LED pilot bulb so I'm not completely dark in front and it is brighter than I thought it would be. FWIW, I don't ride at night but would like to be more conspicuous during daytime riding.
