An assembled wiring harness with relays is obtainable from Advanced Autowire 
(as of a year or so ago, it was $75 ppd), Moss (well over $100, then add s&h, 
and it is just parts so assembly is required), and Victoria British (believe 
already assembled for $25 plus s&h).  I have the Advanced Autowire version and 
am very happy with it.  Your headlamp switch(es) only activate the relays so 
there is a maximum of only 500 milliamps through the switch(es) instead of the 
full current drawn by the headlamps.  The wires to the headlamps on the AAW 
model are thicker than stock, further reducing the voltage drop (current x 
resistance) through them.  I assume Moss and VB also have heavier gauge wires 
from the relays to the heamlamp connectors.

If you want to stick with sealed beam incandescents, fine; but I would 
recommend halogens.  Moss sells Hella halogens (separate bulb), which I have 
and like.  If I was doing it over again, however, I probably would go with 
sealed beam halogens such as the Sylvania Silverstars.  They have a 7" round 
version (H6024 if memory serves).  I think one runs about $20 at Pep Boys.

Additionally, make sure your grounds are good, and clean or replace the 
headlamp switch(es).

     Well, my TR3 is now my daily driver. My cheap old headlamps put out a weak 
yellow-ish light. I was thinking that I should upgrade the headlamp lighting.
     What is the best headlamp upgrade where I don't have to make a new wiring 
harness?
     What wiring harness upgrades are already out there?
     What are other listers happy with?
     TIA,

     Bill in Tehachapi
