AMUNIESUN 4x6 Inch DOT Halo LED Headlights 4 PCS — H4651/H4652 Compatible, DRL & Amber Signal

How bright and long-lasting are these AMUNIESUN halo headlights?

These LEDs run a cool white output in the 5000K–6000K range for clear, daylight-style illumination that improves visibility compared with halogen bulbs. The units use quality heat-sinking and an aluminum shell to manage thermal load, helping rated lifespans reach up to 50,000 hours under normal use.

• Color temperature: 5000K–6000K for crisp white light
• Rated lifespan up to 50,000 hours
• Durable aluminum heatsink for thermal stability
• IP67 waterproof rating for wet-weather reliability

Will these fit my vehicle and how easy is installation?

These are 4x6 inch rectangular headlights compatible with housings that accept H4651, H4652, H4656, H4666 and H6545 styles. They use an H4 plug by default and include H4-to-3-pin adapters so you can adapt older or manufacturer-specific sockets without cutting wires.

• Direct replacement for 4x6 inch housings
• Includes H4 to 3-pin adapters for broader compatibility
• Plug-and-play installation; remove old unit, insert new headlight
• Confirm your light opening measures 4x6 inches before purchasing

What lighting functions do these headlights provide?

Each AMUNIESUN unit integrates four lighting modes: high beam, low beam, white daytime running light (DRL) halo and an amber turn signal. That consolidated design replaces multiple bulbs with a single sealed assembly, simplifying upgrades and improving the visual presence of your vehicle.

• High beam and low beam from a single sealed housing
• White halo DRL for daytime visibility and style
• Amber integrated turn signal for clear signaling
• DOT approval for legal road use where required

How rugged are these headlights in real-world conditions?

The polycarbonate lens and IP67 waterproof rating keep moisture and debris out, while the aluminum shell resists corrosion and dissipates heat. They are designed for heavy-duty use on commercial trucks and road-going classic cars, retaining performance in rain, snow and dusty environments.

• PC lens resists impact and UV haze
• IP67 prevents water ingress during heavy rain or splashes
• Aluminum housing and heatsink for long-term durability
• Built for trucks, vans, and classic automobiles used outdoors

These AMUNIESUN 4x6 halo headlights suit owners of trucks, semis, vans and classic cars that accept H4651/H4652/H4656/H4666/H6545-style 4x6 housings and who want a safer, modern LED setup without complex wiring. They are ideal for fleet operators, restoration enthusiasts and anyone seeking a long-lasting, weatherproof headlight upgrade with integrated DRL and turn-signal functions. If you need plug-and-play replacement performance combined with DOT compliance and heavy-duty construction, this 4-pack covers four positions for a complete vehicle refresh.
