On my 82, I added a relay and went with 80/100 watt E-code headlights -
both high & low beam off the headlight switch.  I then added a fog
light switch to run the inner lights separately.  Works well for me.
If you have any questions, there is a pretty good website which helped
me with problems on my Rabbit
