Hello all,
I started to go to Honda-Tech.com to make a thread there. But, honestly, trust the opinions here more, even though that's a Honda-specific forum.

Problem: I just installed some LED H4 headlight bulbs. I run them alongside my OEM fog lights. All was well when I first installed them. However, on my first trip to work, I noticed a buzzing noise coming from behind the steering wheel area. So, I turned off the headlights, noise went away. Waited a few minutes, turned them back on. Was good for another 15 minutes, than the buzz came back on. Sounds like a buzzing alarm, like on a dryer when it completes its drying cycle of your clothes. A bit more faint, but that's the tone.

So, I got home and installed 20A fuses, rather than the (factory-spec) 10A. That seemed to solve the issue. They now drive about twice as long, before I get my first buzzing incident (about 25-30 minutes). Then, I have to either turn the headlights off, OR turn off my fogs. In fact, I can sit there and push the fog light switch on and off and here the buzzing go on and off. When the fogs are turned on, the buzzing noise happens AND the headlights bulbs turn off.

Today, I tried running 30A fuses. Same thing happened. This is getting ridiculous.

So, my questions at this point:

1. Am I doing the right thing by continually raising the fuse ratings? I'm not going above 30, as that just seems ridiculous...

2. Could I melt anything/wiring running on 20 or 25 amp fuses in slots designated by factory to be 10 amps?

3. Where is the buzzing coming from? It sounds like it's (literally) right behind the fog light button/switch on the dash. Is there a fuse back there in the OEM wiring or is the buzzing possibly coming form the switch itself? Anyone know?

This has been an issue of late, as I have to turn off the headlights on longer trips or (as I discovered today), or run the headlights without the fog lights on.

Currently, I think my solution here is:

-Return bulbs (I hope not, as I like them so far, aside from this issue)

or

-Locate a fuse in the fog light harness that needs to be upped a bit in amperage as well.

What are your thoughts? All in all, I want a safe car, and I certainly don't want these lights to cost me fuel. I got them (partially) to decrease amperage/load on the engine and perhaps even gain a few sips of fuel each tank.

Also, I have contacted the Ebay Seller. We'll see what he says as well.

Thanks for any counsel you can give.
