The Morimoto XB 2.0 HID Ballasts are just as good looking on the outside as they are well-engineered on the inside. They are available in both 35w and 50w versions.
At the heart of the XB H11 bulbs is their perfectly aligned 100% Philips Quartz glass that houses a capsule from APL-USA.
The special Silverado Spec HD Relay Harness features an all-new completely sealed double 40A Relays, 14 gauge stranded copper wire wrapped in durable black tech-flex mesh that looks like a factory harness once installed. No cutting or splicing here: there are only five connections and they're all plug-n-play. Most importantly, the harness includes the proper capacitor to absorb and smooth out the pulsed signal from the factory fog light circuit that plagues these trucks.
