There is a lengthy thread on another forum about the headlight dimming issue. From what I've read, only the 08 4 cylinder Accord does it. Some say it is the ELD (Electric Load Detector), which is located in the under hood fuse box. The ELD would be my guess for the cause. The techs say that "all Accords do this, and it is normal", but there are many 08 (4cyl) Accord owners who disagree.

Very interesting! You are the first person, I think, to mention the ELD. Is it: a) not working; b) is working as designed; c) or the engine management system A/C idle-up can't respond quick enough when the compressor kicks on?
 
I had issues with my 84 Accord which was one of the first made in Ohio and was pre-fuel injection days. The idle speed when set at the 750 spec would drop down almost to the stall point. Honda's cure was to keep the A/C on so the A/C idle-up kicked in. I adjusted the idle speed to 1000 (ah the days of carburetors).

I just searched the Honda forums and found a reference back in 2006.
 
The ELD, first implemented in the middle 90's, cuts the output of the alternator under low load to increase gas mileage. That might explain why the lights dim sometimes when the A/C kicks on.
 
Too many doodads all in the name of gas mileage.

Back when I had my 92 Accord I was under the impression that the ELD would increase the idle speed when an Electric Load was Detected, but now techs say it increases the output of the alternator. Either way, some owners have had success changing the ELD. On some Accords the ELD is part of the fuse box, so those are not cheap to replace ($250-300). Some are separate parts.

That post mentioned something about a service bulletin explaining the ELD. They didn't reference the bulletin number, date, just that it was mentioned in a previous post. The post mentioned something about the ELD being made by DELCO.
 
I found this doing a Google search for ELD + ELD:

There was a TSB for the ELD issue, but it was on previous generation Accords. Sounds like it could be a lot of things including the ELD or the alternator.

Headlights Dim with A/C Compressor ON by katanapilot

My '08 Accord 4 cylinder has the same issue. Taken it to three dealers and they cannot fix the problem. Honda is reportedly working on a fix, but the fix is expensive and invasive. The ELD system is partially to blame, but there is more to it than that. The dimming issue would not be unusual if it occurred at idle (low alternator output) but it occurs also at highway speeds. The ELD signals the engine computer when to place the alternator in high output mode. The alternator is in low most of the time primarily for fuel savings - less load on the engine.
 
I have sent Honda the "Final Opportunity to Repair" notice as directed by the Georgia Warranty Rights Act (Lemon Law). They will have 15 days to fix the problem and then they will either have to replace the vehicle or give me my money back. Since there is no fix available, Honda will be in a bit of a dilemma if I ask for a replacement vehicle. It sounds like all of the I4 Accords have the problem. I'm guessing it doesn't bother everyone, but I have been "flashed" by oncoming cars and more recently cars behind me that think I am repeatedly stepping on the brakes and releasing them.
 
If you have this vehicle, I would suggest you take it to your dealer and start documenting the issue. File a report with the NHTSA website, call Consumer Reports, the Institute for Highway Safety and anyone else who will listen. Honda will fix this but only when it gets painful enough or the word gets out to prospective buyers. Good luck to you all.

After reading posts regarding this issue, I decided to duplicate the problem. In order to do so, I had to put the car in park, put the ac to max a/c with radio on and turn up the a/c. Sure enough, a flicker every 30 seconds. However while night driving I have not experienced this phenomenon. The car is so perfect in every other regard, ( 2008 ex 4 cyl at ) I've decided to ignore it. What are you going to do katanapilot if they replace your vehicle and it duplicates? File Lemon law again?

None of my 3 Toyota's have had the 'heat soak problem'. My 99 Accord does have the headlights dim slightly when the A/C kicks on but it has always been that way for my Honda and probably some other vehicles I've owned too. While this may be aggravating to some, it isn't a problem for me or the car.
