Hi, I haven't been very active on this forum, mainly because I haven't really had any issues with the Fit. Currently, my wife has taken over our 08 MR Honda Fit Sport. We've had HID's on it for 2+ years and just recently, 1 went out. After I replaced the HID bulb, I realized the problem was beyond then bulb and realized that the ballast was bad so I didn't want to wait another few days to receive a new ballast and ended up replacing both of my headlight bulbs with some leftover PIAA H4 bulbs I had from a old Civic.

1 month later, the driver's side goes out and I figure I might as well put back my HIDs so I ordered a new kit with an extra ballast just in case. I just tried installing the new HID kit and when I turn on the headlights, the driver's side will turn on, then flicker and slowly turn off. I had 5 different ballasts and 5 different bulbs (I purchased several to avoid future waits if anything ever goes out) and I experienced the same problems with each set. I went on the forum and searched around for similar problems and after doing so, I decided to check the fuses and low and behold, one of the 20A fuses (#12 or #13) was blown so I replaced that. I go through the same HID kits again and I get the same problem - turns on, flickers, then slowly turns off. I got really fed up and just put the OEM bulbs back in and there's no problems there.

Let me add that I do have HID's in the foglights but I doubt that's problem. I honestly love the HID's because they help me see so clearly and in our GDs, i've honestly haven't had any issues from other drivers passing me by and I don't think they're very hard on the eyes. I wish I can once again have HIDs in my car. I was wondering if anyone has had any similar issues and if so, what's the solution?

Thanks in advance and I gladly appreciate any help or input.

 

I'm definitely no pro with electrical stuff, but if it keeps on doing that (Flicker - then shut off) and fuse blows then maybe it's way beyond the kit/bulb.

Do the regular oem bulbs work just fine?

 

I had this issue on a previous car.
Wire the loom up outside the car to test.

If you hear clicking from the ballast during HID flickering then the ballast is bad. Don't think that just cause you have 5 new ones that they can't all be faulty - these are made in the far east from cheap components.

Easy test. One side is working. First swap ballasts. Does the fault move too? If so, then ballast is your issue, otherwise a bulb could be out.

Final test (but this one damages bulbs) if you flick the high beam on for a split second with headlights off you will charge the ballast for the bulb. After maybe 10 flicks of the beam, there will be enough juice in the ballast for the lamp to remain lit when you switch on lights. It will damage the bulbs but does prove faulty ballast.

 

Worthwhile adding if your kit has 2 earth connections (1 for each light) then check these are good. Check them both as the loom may not be 'conventionally' wired...

 

Find a kit that comes with a relay harness to connect directly to the battery and only uses the stock headlight plug for "signal"

 

Just my 2-cents on HIDs: I drive cars with and without HIDs. I have yet to notice whether the color spectrum of a halogen bulb vs an arc gap created by an HID bub really helps with visibility. There are many factors in visibility during night driving including the lens design, the light distribution pattern, the light power output (lumens),and the color spectrum (related to color temperature). It's almost impossible to do a side-by-side comparison because the lens design of a tungsten filament bulb and an arc are going to different, producing different scatter results. Also, the HIDs produce way more lumens than what's allowed by halogen. That's probably the biggest factor and why people like em. What I've noticed, personally, is that the lens design and scatter pattern of light is what makes the biggest difference in visibility. The color spectrum of light is actually better when it stays toward the red, rather than the violet. Hence, halogen is better than HID for color. Too much blue produces glare because blue light focuses in front of the retina, making it appear blurry. Ever see a blue sign at night and find it looks blurry? It's also why yellow lights were preferred by the French, why fog lights are yellow, and why the military uses red lighting for night illumination. Yet another factor is cutoff. A sharp light cutoff causes the same affect as when you enter a movie theater during daylight. Your eyes need time to adjust. A sharp cutoff between bright and dark during night driving doesn't allow you to see much beyond what's lit up.
