Headlight Question

Has anybody tried the H13 wiring upgrade kit? I wonder if it would cause the bulbs to burn out earlier? It does look interesting though.

It shouldn't cause the bulbs to burn out sooner since it will be feeding nearly 100% of the voltage coming from the alternator and batteries, rather than losing some power through the stock wiring and PCB leads.

AFAIK, the low-beams are the only ones not fed through relays. Ford in its infinite wisdom decided to use the SJB to feed power to the low-beams.
