I notice at night when I turn on my high beam there is a sort of dark spot created in my visual area. The high beam works well, but leaves a large dark area where the low beam would shine if it were on.
I found a lot of posts and a lot of mixed information so I thought I would clarify it the best I could.
I did mine exactly like this and it works great. The high beam only comes on when I turn it on and when it does come on the low beam stays on with it. When I turn off the high beam it goes off and the low beam stays on.
$15 and some change including tax for the parts needed. All the parts I got at Radio Shack off the shelf (no special ordering needed).
Time:
About an hour or less
Here is how to do it:
The diagram is attached. It is in PDF format.
Parts list:
Relay: Radio Shack part # 275-001 (this is the smallest one they had, measures 1”x 1” x 1”, it is rated at 40A which is way more protection than you need) Quantity: 1
Diode: Radio Shack part # 276-1661 (is about the size of your pinky fingernail) Quantity: 1 pack (comes in pack of 4, you will only need 2)
Inline Fuse Holder for 1 ¼ x ¼” Fuses: Radio shack part #270-1281 Quantity: 1
1 ¼ x ¼” 10A fuse: Radio shack part # 270-1072 Quantity: 1
Tools:
Wire cutter
Needle nose pliers
Electrical Tape and/or heat shrink tubing
Solder gun and solder
Notes about the diodes: The diodes have a gray band on them. The gray band on both of the diodes used should be wired so they lead towards your low beam. On my diagram you will see a straight line at the end of the diode arrow, that straight line represents the gray band on the diode
Notes about the relay: It is a four pin relay. Each pin is labeled on the bottom of the relay. The labels are: 30, 86, 86, 87. The wiring diagram shows which one goes where.
