Frequently Asked Questions
Q: What vehicles are compatible with this H4 ceramic headlight socket?
A: This H4 headlight bulb socket is designed to fit any vehicle that uses a standard H4 (also known as 9003) headlight bulb with a 3-pin/3-hole connector. This includes a wide range of cars, motorcycles, and trucks equipped with H4 halogen headlights. Always verify your vehicle's bulb base type before purchasing.
Q: How many sockets come in one order?
A: Each order includes 2 pieces of the H4 ceramic headlight bulb socket plug, so you can replace both headlight connectors at once or keep one as a spare.
Q: Why is ceramic used in this headlight socket?
A: Ceramic is an excellent heat-insulating material that can withstand the high temperatures generated by H4 headlight bulbs. Unlike plastic sockets, ceramic connectors are far less likely to melt, warp, or degrade over time, making them a more durable and reliable replacement option.
Q: Is this socket easy to install without a mechanic?
A: Yes. This is a direct plug-in replacement for a worn or damaged H4 socket. Simply disconnect the old socket from the wiring harness, transfer the wires to the new ceramic connector, and plug it into your H4 bulb. Basic automotive DIY knowledge is sufficient for installation.
