Is there a way to tell if the Guide Lamp T3 High Beam I pulled out of my 70 98 is original? Do the codes on them mean something? Only the high beams were still T3s. I replaced all of them because it was like driving with flashlights at night and the deer are super-plentiful here in western Washington. I don't like HIDs or LEDs but I still wanted to upgrade to halogen at least.
