What is the difference between H4 vs H11? I ordered H11 bulb for my Prius 3 but they sent me H4. The fitment fit but it isn't tight into the socket. I am more worried water get in. Thinking of sending them back
H4 is typically a dual filament bulb if I remember correctly; the base is a similar size to H11 though. I would ask them to swap with an H11 bulb though if its loose in the socket.
H4 is for the Gen2 non-HID Prius. The halogen version is a dual filament bulb. The base is different from a H11 bulb. Exchange it for the correct bulb iPhone ?
