drl with high beam

I'm guessing to limit current.  It better be a big resistor.  That 1.2 ohm resistor will allow 6A per bulb - what is the watt rating on the lamps? 

A "better" way to do it would to pulse width modulate the high beams.  You won't have to worry about finding a >75w resistor to safely do it.  I'm guessing on the required watt rating, but I wouldn't be surprised if it was higher then 75w.

Oh, I just saw the 7.5A fuse - I don't think that will work.  The 1.2 ohm resistor will allow 12A to pass through it.  If you fuse the system at 7.5A either you will blow a fuse or your high beams won't pull 7.5A.  The resistor will reduce the amount of current your high beams consume, but it will NOT reduce the amount of current in the circuit - the resistor will dissipate that difference.  If you give me the watt rating of the high beam I could calculate it all out.

You should also put the fuse as close to the battery as possible, NOT coming out of the relay.
