HID lights "fix" the flicker/blink/dim problem for Honda Accord 4-cyl.?

I love our little '08 Honda Accord 4-cylinder, but we do have the pretty noticeable blink/dimming/flashing of the headlights when the AC is on. We just did a 12 HR trip to OK and back and could really see the flash on I-40 and I-72.

I've heard that switching over to HID lights for the low beams seems to be a work around for the blink/flash because the HID lights are wired directly into the 12 volt side of the electrical system and don't see the voltage drop when the AC kicks in. I just wanted to confirm with others that folks are not seeing the flash/dim/blink with the HID lights.

Thanks for any info.

I think it was discussed at great length that the battery would not fix the flicker issue in the 08 4-cyl since the problem is linked to a drop in voltage from the alternator from 14.4 to 12.2 or something similar. Others traced this issue to the ELD and existing circuitry not notifying the alternator that the AC compressor was about to kick on and the voltage dropping. Others pointed out that a larger battery would not help fix this problem, but only assure that a solid 12 V's were provided. I think since the battery is functioning around 12 Vs.

Previously I think some folks found that switching over to the HID lights was a work around, but I never heard back on any of their success/failure. I think folks stated that this worked because it was directly connected with the battery, i.e. an ~stable 12 V connection.

I was just trying to get some follow up info since I have some time to look into switching over to HIDs.

Thanks again

The answer is yes and no - I changed out to a much larger batt with 2,5 x the cranking amps of the toy batt Honda gives you and found the following. It did not cure the flickering when the AC went on for ECM reasons listed above.But it did reduce it to where I forget it does it. It did however completely eliminate the flicker that occurred when another accessory went on, like a window motor or the stereo. In addition, starts are quicker and the motor seems to idle stronger. Any batt with more than 700 CCA will do.

I'm in the same situation as AznX. My headlights don't dim, but my tail lights and interior lights do.

The interior illumination of the odometer has no effect on the headlights dimming. If you're referring to what I said about the interior lights dimming, it's the overhead map lights and dome light. My trunk light used to do it too, until I got cold cathodes in the trunk.

The dash lights dim very slightly, yes, but the overhead lights and trunk lights dim just as bad as the headlights and taillights.

Yeah...There have been some pretty extensive discussions on this topic and describing the characteristics and possible fixes/work arounds:

http://www.driveaccord.net/forums/sh...ighlight=Flash

http://www.driveaccord.net/forums/sh...ighlight=Flash

Hope these help provide you some additional info about the issue.

I looked into going the Lemon Law route, but you end up loosing a bunch of money on that route vs. just sticking in some HIDs (if that provide a good long term solution) Still doesn't address the tail lights or the interior map lights and trunk lights, but cie la vie.

I was really interested in folks who have installed HIDs and seeing if it really did make a difference long term.

Cheers

I installed HIDs with a relay and no longer have my headlights dim. I'm not sure if my map lights and dome light dim because I never use them.

Any digitally controlled highly efficient plug and play complaint HID system like our DIGITAL brand or even a moderately efficient ballast design system with a relay harness and decently efficient ballasts won't dim under fluctuations in the ELD system. Older flyback feedback ballast designs will pass some fluctuation on to the bulbs, but you will likely never see it, it is just causing unnecessary damage in the long run, no matter how it is wired.
