This is a Unity 330 Series Post Spotlight with a Chrome Housing, p/n 330B.
The 330 series post-mount spotlights feature a 6" halogen lamp which utilizes an H3 bulb for availability and economy; it is rated at 245,000 candlepower, 12 volts, 100 watts and 100 hours lamp life. The lamp has a polycarbonate lens that is break resistant and contains an ultra-violet ray inhibitor to minimize clouding or yellowing. The beam pattern is sharper and therefore provides less glare. The new designer-styled 330 series feature a head assembly made of high impact ABS with heavy-duty chrome finish. They are designed to compliment both modern and classic vehicles, and provide long service life.
Note: Installation kits are sold separately. Please consult the Unity Application Guide below to find the correct installation kit for your vehicle.
The 330B Spotlight works with dozens of vehicles. You can find the right vehicle, model and year in this Unity pdf guide.
