Ceramic angled H4 bulb sockets / lamp holders by Amio, model 22976, ceramic connector sockets

Angled ceramic H4 bulb sockets by Amio model 22976 are ceramic connector sockets designed to accept H4 automotive bulbs. Constructed from high-temperature ceramic material, these angled lamp holders provide electrical insulation and heat resistance for headlight or auxiliary lighting installations. The angled shape facilitates compact mounting and correct lamp alignment in tight engine bay or assembly locations and is suitable for replacement or custom wiring where a durable H4 holder is required.

Advantages

The ceramic construction offers improved thermal stability compared with plastic holders, reducing risk of deformation and maintaining reliable contact under prolonged heat exposure. Angled form factor enables easier routing of wiring and better fitment in constrained spaces. The sockets are compatible with standard H4 bulb bases and provide secure mechanical retention and electrical connection for automotive lighting applications.

Suitable for

• Replacement of worn or damaged H4 lamp holders in cars and trucks
• Custom headlight or auxiliary lamp wiring and retrofits
• Applications requiring heat-resistant, insulated bulb connections
• Tight mounting locations where an angled socket improves fit

Key specifications

• Socket material: ceramic for high temperature resistance and electrical insulation
• Bulb type compatibility: H4 standard three-contact automotive bulbs
• Form factor: angled connector design for compact mounting
• Contact style: three-contact receptacle suitable for H4 base configuration
• Intended use: headlight and auxiliary lamp electrical connection

How to use

Turn off vehicle power before installation and allow cooled components to avoid burns. Remove the existing bulb holder or access the lamp housing, disconnect electrical feed wires, and remove the old socket if present. Connect vehicle wiring to the ceramic socket contacts following the H4 three-contact configuration, ensuring correct pin assignment for low beam, high beam and ground. Secure the socket within the lamp housing or mounting bracket using appropriate clips or fasteners; avoid over-tightening which may stress the ceramic. Insert an H4 bulb into the socket until it seats firmly and verify correct alignment and electrical function before reassembling the lamp housing.

Usage recommendations

Use the ceramic angled H4 sockets in systems where heat resistance and reliable insulation are important. Avoid striking or dropping the ceramic parts during handling; if wires require insulation, use heat-resistant insulation or appropriate crimp connectors rated for automotive temperatures. Verify proper electrical polarity and secure connections to prevent arcing and ensure long service life.
