As shown in the video, 7443 is dual filaments, 7440 is single filament. 7443 switchback LED turn signal bulbs work for 7440 turn signal lights? The OEM halogen bulb is 7440(single filament), which means it has one function, turn signal only. Also, the power cable just has two wires, the positive wire for turn signal light, the negative wire is the ground wire. About 7443 dual filament bulb, the power cable has 3 wires, two positive wire, one negative wire. One positive wire is for turn signal, another positive wire is for daytime running light or parking light. So, if you try to use 7443 switchback LED bulbs to replace the OEM halogen bulb 7440, the turn signal light(yellow light) will work well, but the white light does not work. Because the OEM power cable just has two wires.
