IR headlight only has two wire inside instead of 3?? sealed bulb blew and is cracking
Hi I have this IR light that I am trying to install. I opened the lamp up and followed the back of the plug (which has only two wires even though bulb has three prongs). The plug has both wires noted as "ground" and "drive". The two wires from the plug go right into the rear housing rubber connections. I made my connection and the lamp got warm then cold. I opened it up and tried the light again but nothing. The sealed beam was not clear anymore and a crack began to form on the face. The crack has gone around to the back of the bulb too now.
Doing some research shows the plug is mislabeling the ground as the left prong when it should be the middle one? When I tried to power the bulb using the middle as ground and one of the side prongs as + it didnt work on one and on the other it lit up for maybe 5 seconds and then stopped. At the same time I saw smoke making its way through the crack.
This leads me to believe either the bulb is wrong or the plug is wrong. Inside the housing the mounting stud has a rubber isolator. According to my search the stud should have been ground. But I also dont know if the plug is wired correctly or did I mess up in understanding how it needs to be wired? Can someone let me know how the plug is supposed to be wired? (is ground the middle or the side one?)
I am using this on a HMMWV in place of the blackout hood light, so it has only two connections one was a ground stud which I clipped to work with the IR housing plugs. All my other blackouts work fine. And when I test a 24v bulb using the IR housings 3 prong plug, it lights up fine.
Oh and headlight NSN is 6220-00-984-5180
