Molex Bulb Sockets provide high-quality performance, robust designs and a wide selection for automotive applications.

S8 Wedge-Type
Molex's S8 wedge-style bulb socket is the first version in the market to feature a one-piece design, which simplifies assembly and reduces inventory and component costs.

The Molex S8 bulb socket also includes a patented individual wire seal design that provides easy attachment during the crimping process, along with superior sealing and usability.

Push-and-Turn (PT) Type
Molex's standard PT sockets are primarily used for rear-combination and turn-signal lamps. These proven sockets accept industry-standard bulbs in simple, lightweight designs.

Standard Wedge-Type
Molex's standard wedge-type bulb sockets with robust design are ideal for harsh environments such as door courtesy lamps, back-plate lamps, tail-signal lamps, and front-and-rear combination lamps. The wedge-style mating interface is user-friendly and offers space savings.
