The headlights were another popular upgrade that I had read about to both see and be seen more easily at night. I upgraded from Sylvania XV to Cibie E-code headlight housings with Philips CrystalVision Ultra xenon bulbs. Looking at the light output on the wall (below), they don’t seem much brighter, but on the road, the difference is night and day.
