Putco's Silver-Lux Pro LED headlight bulbs are custom designed with aluminum towers and built with high-power Cree XHP70 LEDs with 6000 Lumens of light output per kit. Shining 6000K white, these upgrades feature a clockable collar, allowing you to adjust the light beam as necessary for your vehicle. Like the Putco Nite-Lux kits, these also feature Putco's exclusive patented 100 percent copper weave cloth heat-sinks. The driver assembly is now smaller and fully enclosed. Silver-Lux Pro kits are designed specifically for use with projector lenses.
