Vehicles equipped with a separate 9005/HB3 high-beam and 9006/HB4 low-beam configuration deserve a headlight upgrade that handles both positions equally well. The SEALIGHT S7S 9005/HB3 + 9006/HB4 LED headlight bulbs deliver exactly that — one package, two pairs, complete front lighting performance from the brand's flagship wireless headlight series.

As the brightest 9005 and 9006 LED headlight bulb combo in SEALIGHT's lineup, the S7S series was engineered to push output, reliability, and ease of installation to their practical limits. Each bulb produces 16,500 lumens at a true 65W — a combination that floods the road ahead with crisp, cool-white light while maintaining electrical compatibility with your vehicle's OEM systems. This makes the S7S the ideal 9005/HB3 and 9006/HB4 halogen bulb replacement for drivers who refuse to compromise on visibility or reliability.

900% Brighter Output

With 66,000 lumens per set, these brightest LED headlight bulbs are designed to transform dark-road visibility. They are dramatically brighter than halogens, giving you a more confident view of lane edges, animals, signs, and changing road conditions.

The S7S beam pattern is optimized for maximum forward throw, extending usable illumination to approximately 1,500 feet ahead of the vehicle. At highway speeds, this additional reaction distance can be the difference between avoiding a road hazard and not seeing it until it's too late. The crisp 6500K white light also improves contrast against darker road surfaces and makes lane markings, road signs, and animals pop more clearly into view.

Built for Long-Term Durability

The IP68 waterproof rating ensures that weather is never a concern. Active thermal management prevents heat buildup from reducing brightness or shortening lifespan — the bulbs are engineered to maintain consistent output across extended driving sessions. With a rated lifespan exceeding 60,000 hours, these are the last headlight bulbs most drivers will ever need to buy for their current vehicle.

3-Minute Plug-and-Play Installation

The plug-and-play nature of the S7S design means that replacing your 9005 and 9006 halogens requires nothing more than twisting out the old bulb and twisting in the new one. No wiring knowledge, no special tools, no professional installation.

Ans: SEALIGHT S7S 9005 9006 LED bulbs fit a wide range of popular models that use 9005 and 9006 as the high beam and low beam headlight bulbs, including the 1999–2006 Chevrolet Silverado 1500, 2002–2004 Chevrolet Silverado 2500 HD, and the 2005 GMC Sierra 2500 HD.

Q: How can I check if they are compatible with my vehicle?

Ans: Please check your vehicle’s owner's manual or examine your original factory bulb to verify the correct 9005 or 9006 sizing before purchasing.

Q: Are SEALIGHT S7S 9005 9006 LED bulbs CANbus compatible?

Ans: Yes, the S7S series draws 65W per bulb, which matches the OEM-load of standard factory bulbs, making them CANbus ready for 99% of vehicles. For vehicles with particularly sensitive CAN-bus systems, SEALIGHT can provide an additional external decoder — contact support if needed.
