Product Description The DEUS-0251E is a premium OE-spec 3-pin socket designed to house the standard H4 (PX43T) halogen bulb.Manufactured by Swiss Auto, it is engineered to solve the common problem of “flickering” headlights and terminal melting in legacy Royal Enfield models. The holder features high-conductivity brass terminals that ensure a stable flow of current, reducing the electrical resistance that often causes heat buildup. The outer casing is made from a high-temperature resistant polymer (or ceramic-infused plastic) that maintains its structural integrity even during long night rides. It comes with pre-crimped, automotive-grade copper wiring and a protective rubber boot to prevent moisture and dust from entering the headlight casquette. Key Features: 3-Pin H4 Compatibility: Specifically designed for H4 Halogen bulbs (High Beam, Low Beam, and Ground). Heat-Resistant Construction: Built to withstand the intense thermal output of 55/60W bulbs without warping or melting. Corrosion-Resistant Terminals: Features brass/copper alloy contacts that prevent oxidation, a common cause of dim headlights. Plug-and-Play Integration: Matches the factory wiring colors of the Bullet Standard and Electra for easy installation. Moisture Protection: Includes a secure back-shell design that keeps the electrical pins dry and free from road grime.
