4x6 Inch LED Headlights – ADR Compliant Sealed-Beam Replacements
Our 4x6 inch LED Headlights are rectangular sealed-beam replacements for older vehicles originally fitted with halogen sealed beams. All models on this page are supplied as ADR compliant units with a symmetrical beam pattern.
Direct Replacement for 4x6" Sealed Beams
Many classic cars, trucks, 4x4s and motorcycles use a rectangular sealed-beam headlight. LED upgrades typically connect via a standard H4 high/low plug, with some models including additional wiring for DRL or indicator functions.
ADR Compliance Explained
In Australia, true ADR approved headlights require formal certification and asymmetrical right-hand-drive beam patterns. Due to the universal design of original rectangular sealed-beam headlights, which use a flat (symmetrical) beam pattern, our aftermarket 4x6 inch LED headlights are designed with the same symmetrical low beam to meet ADR requirements for sealed-beam headlamps.
H4 Polarity Converters for Earth-Switched Vehicles
Some older vehicles use an earth-switched headlight circuit, which can cause LED headlights to operate incorrectly. Our H4 polarity converter is a simple inline adapter that restores correct operation without modifying factory wiring.
