Headlight upgrades
So most of you are probably aware of the H4 headlight upgrade, along with the more important addition of relays to allow for increased power to the lights. I'm no electrician, so this was a first for me, but I do have some understanding of how electrical things are supposed to work. There seem to be a lot of products out there, including some "kits," which I had to weigh the +'s and -'s of. Probably the most popular kit can be found here: Daniel Stern Lighting kit
I chose to do a DIY kit, using parts I found on Amazon:
1. Inline fuse holder, 10awg
2. Bosch 5-pin relay
3. 5 pin relay socket
4. 10pc heat shrink tubing
Total cost, $20 and change after shipping. Next time, I'd try to find the 4-pin relays, but I think these will work for now.
Also got rid of the old enclosed bulb headlights, in favor of some affordable Autopal off of eBay from this seller: eBay autopals OK, I know they're not Cibies or Hellas or whatever. But they are cheap ($40 shipped) and easy to replace. I can't remember the last time I ever broke a headlamp, but let's just wait for the scientific results before we start criticizing...
Stock headlamps, no relays:
Autopal headlamps, 55/60W, no relays: (this photo used nearly the same settings, but with a slightly shorter exposure, so expect that the lights are a tad bit brighter than they appear relative to the last photo)
Autopal headlamps, 55/60W, with relays: (this photo was taken using the exact settings used for the stock set-up, no relays)
OK, so there are the objective results. Subjectively, I estimate 2-3X as much light is coming out of these, and it's a white light. It's incredibly better.
I also had to pick up about $10 in electrical gear from HD - including split loom tubing, about 20 feet of 12g stranded wire, some basic connectors, hardware to repair the headlamp bucket, etc.
I found a great spot to mount the relays, just inside of the fresh air intake, behind the D side headlamp, using the stock holes that the intake gasket mounts to:
Grounds are not dedicated and use the factory headlamp ground sites just under the fresh air intake. Other than the extra set of wires, you wouldn't even know they were in there:
You'll also notice the two-barrel horn set I picked up from the scrap yard, $15 from a 80's era F-150 I mentioned above. It does for the horn what these relays and headlamps did for the lighting situation.
Final cost, somewhere in the neighborhood of $100. It was a fun project, took a weekend or so in between running for parts, watching the Giants mess the bed on Sunday, and trouble shooting a broken headlamp bucket. I'd give this upgrade a
