This could be a better, cheaper alternative to the HIDextra....warranty seems better...I'm still waiting to find the time to swap out ballast to troubleshoot my low output issue on one bulb.

Second Update: Received two (2) new replacement 8000K bulbs (with harness) from HIDextra in the mail today....so it looks like HIDextra stands behind their product. :yes:
