Hi, everybody. Andy here with etrailer.com. Let's take a real quick look together at the Sylvania SilverStar Rectangular H4656ST Sealed Beam Halogen Headlight. Now, this is going to replace your standard equipment halogen headlight with the same grade and specifications. And as I mentioned, the bulb type is H4656, and the base is A-3. And the reflector shape is going to produce a broader beam at a greater distance with a defined edge and greater contrast.
This light features a 4,000-Kelvin color temperature, which is going to emit a sharper, balanced white color than the 3,200-Kelvin options. This light is rated for 100 hours. And your harness is going to plug into the back of this light. You're just going to line up the three blades there that you see. And just to give you the further confidence that this is going to work for you, let me set this back up again, I'm gonna retrieve my ruler here and give you some measurements.
So looking at the overall length, we're sitting right at 6-1/2 inches. The overall height, about 4 inches. And let me see if I can give you the depth as well. Just measuring from the face of the light to the end of the prongs there, I'm gonna say about 4-1/2 inches or so. So this light is going to be legal for on-road use.
It does meet the Department of Transportation regulations for performance and life. And as you know, when you're replacing your bulbs, it is recommended to replace them on both sides of your vehicle at the same time just to maintain that consistent light color and level. Well, that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy.
Thank you for joining me.
