Review on SEALIGHT S6 9006/HB4 LED Bulbs, 18000 Lumens 600% Brightness 6500K Cool White, 9006 LED Bulbs With 60000 Hours Lifespan, Plug-And-Play Halogen Replacement Bulbs Kit With Cooling Fan, Pack Of 2 by William Fowler

This set of two 9004 LED headlights from Sealight arrived very well packaged and iyeact. According to the product page they are 18000 lumens and 6500K cool white bulbs, I have no way to verify the brightness. These were pretty easy to put in, my husband did have a little bit of problems with the retainer rings but he always does with the Dodge Ram. It took him about fifteen minutes to install one and ten minutes for the second one. These are a lot brighter than the halogen headlights that we had been using. They would probably be brighter if the headlight lenses were clear, but the truck is old and the lenses are yellowed. These have the heat sink built in, not sure of how long that they will last. I will update this review if they don't last very long. The difference in the brightness compared to the old halogen bulbs is so much it's unreal.
