How can you tell if a light is a 6 or 12 volt light. these are the lights in question. I put the one in the chrome housing the other is in a factory ford housing but not sure of details of it. Posted from the TJJ App for iPhone & iPad
Take the bulb out and see if it says in the back or if it has a part number you can search. Or hook it up to 12v and see if it blows, that's how I usually check
Hook it to 12V. If it burns out, it was 6V If it's a sealed beam, it might say so on the back or there may be a number that you can reference. Edit...looks like ev88f and I are brothers from a different mother
