I bought these to replace a weak two pin reflector in my 4 inch halogen headlights. (12 volts). The halogen headlights got so hot that the reflective baffles discolored and cracked. They must also have the pin socket charred and will only work if held properly. I installed these DiCUNO Bi-Pin base replacements and installed LED lights instead. First, it's only about 5/8 inch in diameter. They hold the pins very firmly - you may have to wiggle them back and forth to fully seat them. Nice work! The hardest part of this job is stripping the wires from the old two-pronged wires, as they aren't strippable. From them you need to carefully remove the insulation. Once that's done you can use regular wire nuts as LEDs don't get hot like halogens. Thanks for a great product. These two pen holders are how all two pen holders should be made. Now if you just made a wire stripper for high temp insulated wire.
