SCA Shift Driving lights as work/reverse lights.
Along with the PRS and CB aerials they make my truck pretty inconspicuous!!

I would have more lights but the alternator doesn't want me to!
But the best mod I made was a relay harness. It is identical in layout to
this one. Now it cost me either $40 or $140 from Auto Electric City in Blenhiem and is worth every cent. So much brighter. A good rule of thumb I heard was 10% of voltage drop equals 30% light output lost. I think I had 10v-11v at the lights before fitting the relay kit. And +50% bulbs helped. (+90% next time I think) I have made the modification shown in that site to have the dip beams stay on when the high beams are on and love it. There is no changeover delay, the highs just come on and drop off. Gives a better spread of light as well.
The Eclipses give me pretty much 180 deg illumination. Doesn't feel quiet so claustrophobic. Here is a
