Title: HID Ballast Issue
Post by: ColoradoB5 on November 13, 2007, 09:43:51 PM
So I think my passenger ballast for my Phillips HID is going bad.  It comes on and runs fine until I drive over a bump and then I have to shut off the lights and turn them back on, which works...until I hit another bump.

Have any of you running an HID system had problems like this before.  I want to make sure I diagnose it correctly so I don't waste the little spare time, and more importantly, money, that I am going to expend to fix this issue.

I did a search on PassatWorld, which is where I got them and I also contact the guy that organized the group buy where I got them.

I definitely put more stock in advice I get here, so here I am.

TIA,
Dub

I am sure you are right that it is a ballast.  But if you want to try a different bulb, just to make sure that is not the case, I have a spare that you can use.  Let me know.

what about your connections? Seems strange for a ballast to go out when you hit a bump, then the system charges up again.  My guess would be connections or faulty bulb.  If you had a flickering or slow start up, or intermittent start up, I would think ballast.

I am going to switch the bulbs to see if that is it.  Based on the fact that the light goes out when I hit a good bump with my stiff suspension, I think it is the bulb too.

The guy I bought them from on PassatWorld (Fabio, aka 1.8Tabamura (I think)), says to get them here:

I was amazed at how much prices have come down.

$34 per bulb is not bad.

you can buy complete kits for less than $100 now.  Charles got a kit that I helped him install, same quality, if not better, than the kits I bought years ago for $350.

http://vvme.com/  that is the website he got them from, and to this date, he has not had one problem with them from what I know.  Other folks on Audiworld have gotten those kits as well.  I know 2 MINI owners that used them and they were good kits.

so, you can replace the entire thing for about the cost of 2 bulbs. ;)

Not to sidetrack, but you liked the quality of those VME kits? I was thinking about using them for the S. It's $56 right now for a single beam HID kit!

Also, dub, while looking at some HID issues for the VMW kit I noted this:

A poor ground will cause the HID light to flicker.

I know you don't have that kit, but I would bet that is the type of issue that could occur with any HID kit. Maybe when you hit a bump  it loses it's ground? If you haven't already, double check the ground wire to ensure it isn't corroded and is still making good contact.

yes, I do like the quality of the kit, really, the same or better than the other kits I bought for the Outback XT that ran me over $350.  I would not hesitate to buy one if I needed one, but all our cars have kits in them, well, except the Tacoma, Betsy does not want them...and she "warned" me to not put them in her car, haha.

Yep, the VVME kit is great. Mine are still going strong. I highly recommend the 4300s which put out nice bright white light.

Good call on the VVME.  I will check those out.  $100 can't be beat.  The H7 bulbs I have are $70 each from the hid-bulbs site I posted earlier.

Jay, I did check the grounds and tightened up the connector at the bulb.  That may have something to do with it too, but we'll see.

It that's it, I will be very happy, but I still kind of think it is the bulb.
