SEALIGHT H11/H9/H8 and 9005/HB3 Light Bulbs Combo, 9005 H11 Fog Bulbs with Cool White, Plug and Play, Pack of 4

Great led lights. Bright and a white light no yucky yellow. Lol 😆 would definitely recommend. We have changed all of our vehicles over to these LED.

Came very fast, easy to install and very bright!

I waited 3 months before writing this. I wanted to make sure that the lights would last at least that long.I had been wanting to upgrade my old-school filament headlights to LED for a long time. In the past, there didn't seem to be a good selection of properly spec'd LED lamps for the vehicle. I had tried to use some LEDs for the marker lights, but they didn't last long.Sealight has changed my mind about LED lighting for this truck. The 4-in-one kit with the two low beams and two high beams is perfect - I can replace all the headlights at the same time.The way the individual lights are designed are the way I'd do it if I were the designer: use no fans, and separate the power supply (which generates some waste heat) from the lamp unit itself. It's as hard as heck to dissipate heat from the LED unit, there's little airflow around there, so all the heat sink needs to be used for that. By having the power supply physically separated, the LED unit's heat sink doesn't need to manage that heat. There's a permanently attached pigtail between the LED unit and the power supply unit. This is good design as the physical bulk of the headlight unit is reduced, which is kind of important in the Tahoe, since there's nearly no room behind the headlight unit. Here in south-central Arizona, the under-the-hood temps can easily be 90 C (200 F) or more during the day. Heat is the number one killer of electronics.6000 K is the right color temperature for headlights. The other ones out there at 6500 K are too blue, and the bluer light reflects off fog and dust in the air more, so the glare is that much worse. I had been running xenon bulbs before, and those are positively yellow when compared to these, prolly 3500 K.The pattern thrown is excellent. All four beams are spot on, and I have not had to adjust anything to aim them. The pattern is also wider than the original lamps, which means the road shoulders are more visible now.I have done a fair amount of off-road driving since installing these, in pretty unforgiving environments. My long-range distance has doubled at least, maybe more. And it's daylight white.Connectors are plug-and-play on the Tahoe. No magic required.I'd like for these to hold up at least a year. For me, that's 16 k miles or so, and given my off-road exploring and the abuse the headlights get from that, a year is a good beginning goal.5 stars.Update December 2022.Still love these headlights, both low and high beam. So brilliantly white, with no funky bluish tint.However, for the past 5 months the right low beam has been intermittent. Sometimes it does not light, other times it works fine. And I mean for hundreds of miles, both on and off road. Often, a quick slap on the headlight assembly will get it running again. Sometimes, just turning the headlights off and then on again fixes the issue. When it works, it’s at full brightness. If I remove the headlight assembly, and wiggle the various parts, the only wiggling that seems to make a difference is removing and reseating the lamp itself into the headlight assembly. I see no worn wiring, I was thinking it might be the in-line power converter, but rapping that or wiggling the connector doesn’t make the headlamp work or not.Sealight - can I get just the one low beam headlamp assembly?

I upgraded to these from the Sealight S2S LEDs for my Mustang projector headlights, and love them!A big improvement over the stock housing and H13 halogens.I drive in pretty dark areas and decent lit areas in Massachusetts, and they illuminate the road perfectly. They also illuminate more of the sides of the road as well, so they pair well with my halogen fog lights to catch that and road signs.You should make sure to aim your headlights correctly to get the best distance.I do worry a bit about overheating since they're covered by the rubber dust boot, so I'll see how they handle longer term. I didn't like the S2Ss during rain and snow at night, so I'll see if these are any better when the weather changes

Wonderful light, be prepared for the cooling fans to run a couple of minutes after you turn off the car.

Exactly the quality of bulbs I have been wanting to get. All the brightness one needs and more, all for a very fair price.

I have had these a while still haven't put them on my truck yet.

Great field of view and upgrade for lights on my Focus ST.
