H4 Headlight upgrade ..., stupid question ... Options

[SirAndy]

so, the H4 Headlight Upgrade Kit on pelican recommends a high-power relay for the 100 watt bulbs.

now the stupid question:

do i just need one or do i need one for each headlight?

I had some extra time today so I wanted to tackle this problem. Here's what I did:

Since my low beams are 55W I decided to stay with stock wiring and not touch a thing. I'll run only additional relays and wiring for the 100W high beams. I bought and attached an aftermarket CB Panel in the engine compartment. You see three wires. All 12ga. Left to right is High Beam (HB) left, HB right, and a spare. Should I need to run something from the battery in the future it's nice to have a spare feed already hooked up. The wires go through the bulkhead and under the passenger seat. The third wire is capped off under the seat.

I then ran the wires up the tunnel with the main harness, over the top of the main CB panel and up out to the front trunk. At this point I changed the color of the HB right wire to white.

I made a small aluminum bracket to hold the relay to the headlight motor cover. I pulled 56a from the headlight bracket, fed it back through the opening to the bucket, and attached it to terminal 86. The original power wire (56a) that would turn on the highbeams now powers the relay. The power feed from the battery went to terminal 30. I made a wire to run from terminal 87 to go to the headlamp. And another, the green one, to go to ground from terminal 85.

I showed only the left side but the right is set up exactly the same.

I like using the stock wiring in this way. As mentioned previously in this thread it alleviates a lot of extra wiring and work. Also I have two CB's prior to the headlight. A good safety margin. I haven't tried it out yet since I need the battery to remain out of the car for another repair.

Thanks for the help all! (IMG:style_emoticons/default/beer3.gif)
