Will the stock wiring harness support the additional amperage draw of the HID?

the HID draws on an average 3.2-3.4 amps and 35 watts
OEM bulb about 4.6 amps and 55 watts (low beam).
on initial startup though, I've read that there could be a draw of up to 10 amps for the igniter to fire. this takes place within 3-5 seconds.
our wiring should be able to handle those short loads.
In any case the fuses should/would protect our wiring.

this is some of what was discussed in our motorcycle forum when these kits started coming out. YMMV -Harry

i was doing a litt elooking on ebay and found a lot of the kits you were talking about.... im curious though what hte difference is between teh kits that are $75 bucks shipped and the ones that cost 300 or more. they have HID conversions for the H4 bulb that go for outrageous prices. i wonder if the cheaper units may not last as long. i wouldnt know what brands are reputable or not

if the HIDs burn at a lower temp than high wattage halogen bulbs then i dont see why you couldnt put an HID kit for a 896 bulb in the fog light space. it would only run on 35w. the only thing i dont know is where you would mount the ballast. Harryscarlot had a pretty slick looking setup hiding the ballasts in the headlamp housing but im not sure where there would be room to do this for the fog lights. although i would love if someone could prove me wrong on that one

The instructions that came with mine said something like that and added that a higher amp fuse maybe required. I have been using them everyday since I got them. No blown fuses or fires yet

I'm thinking that, during my summer leave block, I'm going to get an H4 set as well as an 800-series set of the slim-ballast HIDs off eBay. This will be around the beginning of May, so if no one else has done it by then, I'll let you guys know!

I didn't know until recent posts have popped up, but Impala Balko wrote up a thread on HID lighting too a few weeks before I started mine. I didn't know at the time he started a thread on his install. I hope he doesn't think I stepped on his thread, so give props to him too As for hiding them in the headlamp housings, that is the only place to put the ballasts since we have the roll-over headlamps. So, I didn't invent that spot. just the only logical place.
I think there is plenty of space in the inside corner of your bumper cover when you open the hood. There is plenty of wire to mount the ballast away from the lamp. If I wanted to spend more money, I would get another kit for the fog lamps. Anybody want to buy me a set to try out?

I wouldn't install a higher amp fuse than the factory put in. The wiring is on rated to handle the amperage that the factory fuse rating designed it for. If you start blowing fuses, there is another harness you can buy that you wire directly the positive wire to the battery. it comes with relays and fuses. this harness lets the igniter get it's higher amperage draw for starting from the battery through the new harness bypassing your factory wiring. I've not had to go this route as of yet.

what's this 800 series??
And lastly, I was made aware (by corvette90) that your foglamps will not come on after you install the HIDs. I'm still working on this. The low beam filament was giving a ground to the fog lamp circuit. It now acts like I have high beams on the whole time, not letting the fogs come on. I have been waiting for the snow to go away before I pull the Vette out to solve this puzzle. If someone has fixed this issue, please chime in. DO NOT ground the high beam (green wire) even though it will let the fogs come on. As soon as you switch to high beams, you will blow a fuse or worse. -Harry

The 800 series is just the type of bulb in the foglights (stock bulbs are something like 880, the 50w version is 889, or something like that). I read about the foglight disabling troubles; I guess I'll just have to figure something out. However, I'm not getting a bi-xenon kit, so I won't have high-beams at all. With that being said, I might just try to ground the high beam wire, since I'll never switch to high beams. I guess we'll see.

As for the price, I figure I would have bought a $280 headlight HID kit had I not read this thread, and how the kit is $75...so even buying one for the fog-lights as well puts me at $150, much less than I planned on spending in the first place (and was willing to spend...)

I was worried about that too. I'm using the stock fuses so I know it can handle it.

I think I will try the HID in the fog lights. My fog lights do work but seeing blue HIDs and yellow fog lights just don't look right. I saw a kit on ebay for $49 that I may get but his description of the lighting maybe incorrect.

yeah, i can imagine seeing those crystal white HIDs with the crappy stock dim fog lights underneath would be frusterating. please let us know if you do! we want plenty of pics of the install. if you get everything working on yours, i will probably be doing some light shopping on ebay very shortly thereafter!

Just got the correct Digital Slim Ballasts in the mail today. WOW
these things are small!. I plugged them in and they fire up and don't have any sound coming from them (the old ballasts emitted a high pitched tone). They also seem to charge the bulb faster. I'll let you know how well they work as time goes by. These are the ticket for those places you don't have much room like the bumper area where the fog lamp ballasts would go .

There are all kinds of different style HID lights. The difference in cost is based on the style of bulb. The $75 bulbs only have the low beam, no high. The ones around $100 have an HID low beam and a filament high beam. The ones costing $130 plus have an HID low beam and a solenoid that toggles the bulb into the high beam position.

The type with the HID low beam and the high beam filament may be the solution to the fog light problem.

nope, just the low beams, you'll see that you won't need high beams after you have HID.

My sister has the low beams on her civic, they are ok, I would have to say when she had the high beams on her gsx it was better.

I was browsing the forum all day (like I normally do) and ran across this thread:

Check out post #6. Might solve the fog-light problem. Apparently you can just ground the fog-light itself by cutting the wire that goes to the headlight, and simply grounding it to the frame.

just read that same post myself. just gotta check that out too.
I also took a look where you would put the ballasts for the fog lamps and there is plenty of room.. Both sides have the same amount of space available. just gotta break down and buy a set . You could either buy a set of the slims, or you can still fit the regular size ballasts in the area pictured. C'mon, someone try this. I'm buying my wife an BMW X5 Monday and running a little short on pocket change...



the slims just might fit in that hole where the wires run through the reinforcement.
