ONLINE LED STORE 4x6 LED Headlights H4 2A1 Sealed Beam 4pc — 6000K, IP67 Weatherproof

True Mods 4x6 H4 2A1 sealed-beam LED headlights replace standard 4"x6" halogens to deliver brighter, whiter illumination and durable, weatherproof performance for trucks and trucks-based vehicles.

These TRUE MODS 4-by-6 LED sealed-beam units from ONLINE LED STORE are designed as direct-fit upgrades for a wide range of vehicles that use the H4/2A1-style connector. Built with a black housing and a focused optical lens, the lamps provide a 6,000K white output and IP67 protection, making them suitable for highway driving, heavy-duty truck use, and daily street duty. The plug-and-play H4 base simplifies installation while the sealed-beam form factor preserves original mounting and aiming geometry.

How do these headlights improve visibility on the road?

The LEDs produce a crisp 6,000K white light that increases contrast and road clarity compared with many older halogen sealed beams. You get a stronger, more focused beam pattern for both high and low settings, which helps highlight lane markings, signs, and obstacles sooner.

• 45W total output with distinct high/low beam performance
• 6,000K color temperature for clearer night-time perception
• Engineered optical lens for improved beam cutoff and spread

Will these fit my truck or classic vehicle without wiring changes?

Yes — each lamp includes a pre-attached 5-inch H4 (2A1/1A1) connector intended to swap into existing H4651/H4652/H4656/H4666/H6545 style sockets. That means no cutting, splicing, or relay installations for many common fits; just unplug the old sealed beam and install the new TRUE MODS unit.

• Pre-wired H4 connector for plug-and-play replacement
• Direct replacement for standard 4" x 6" sealed beam housings
• Compatible with many light sockets used on trucks, SUVs, and classic vehicles

Are these headlights durable enough for commercial truck use?

They are built with an impact-resistant polycarbonate lens and an IP67 enclosure to resist dust and temporary immersion, so they withstand highway debris, rain, and road grime common in commercial settings. The sealed-beam construction prevents moisture ingress and keeps the optics consistent over time.

• IP67-rated housing for water and dust protection
• Rugged polycarbonate lens resists chips and cracks
• Sealed-beam design reduces internal corrosion and fogging

Which makes and models are these most commonly used on?

These 4x6 rectangular LEDs are frequently chosen for heavy-duty trucks and many older passenger trucks or SUVs that came with 4-by-6 sealed beams. The product listing calls out compatibility with a broad list of Peterbilt and Kenworth models, plus many Chevy, Dodge, GMC, Nissan, Jeep, Toyota, and Freightliner vehicles that use H4-style sealed beams.

• Common semi-truck fits: Peterbilt 379/378/385/377 series and Kenworth W900/T800 families
• Also compatible with many Chevy, Dodge, GMC, Nissan and Jeep models using 4x6 bulbs
• Direct replacement for H4651/H4652/H4656/H4666/H6545 style sealed beams

Who is this for? These TRUE MODS 4x6 LED sealed-beam headlights target drivers who need a straightforward, reliable lighting upgrade without modifying existing headlight mounts or wiring. They’re ideal for owner-operators and fleet mechanics seeking improved illumination and weather resistance on semi-trucks and heavy pickups, as well as restorers or owners of classic vehicles that retain the 4" x 6" sealed beam format. If you want a plug-and-play LED conversion with a sleek black housing and rugged IP67 protection, these units are a practical option.
