Well, I finally got around to installing my HID setup after getting SOOO sick of the WAY to dim low-beams. Overall, it was an easy install-after I figured out placement. INCREDIBLE results with 6000K. Honestly, the lights look IDENTICAL to those of our Infinity G-35x. (which uses the same system as Audi, Nissan cars, Lexus, BMW, etc) Very crisp white, with a nice blue hue. The projector housings in the Viper are actually very good, and fit the HID bulbs perfectly. The housing also contain cut-offs, like HID projectors do, to avoid blinding. (though I dont know HOW you could ever blind someone with low beams in a stock Viper) Perhaps Dodge thought ahead on this issue, and they did intend to put HIDs in the projector housings later. Another curious feature of the projector housing is the fact that it has a removable rear plate, and it looks to have under it a D2S socket...? Almost like it was an HID setup ADAPTED to Halogen. I may look into this later.

Other than that, I did a little research on this subject too. It seems in the HID aftermarket, there are two types of systems out there. those that you plug the factory wiring harness right into the ballast, and those that you plug a whole new wiring harness in with a Relay, ground, positive, etc. From what people SAY, by plugging the ballast right into the factory harness, some cars will melt wiring.

Well, the Viper isnt one of them.

(not that I am surprised... some companies drum the fact that you NEED all that extra wiring to keep the load down......then in the next sentance say how much lower of a draw HIDs put on the system)

After looking at how these aftermarket systems are constructed, and then comparing it to the Viper's system, they are pretty much identical in construction. So, I did a test. I made my system as simple as possible, keeping the wiring down to a minimum. Factory plug connects directly to the Ballast, ballast connects to the bulb, done. finished. Stock 10A per side fuses left alone in the fuse box.

The Test:

After leaving the Viper in the garage for 5 hours straight, with the lights on and a battery tender to keep from killing the battery, I measured the temperature of all the wiring, fuses, etc and compared it to that of wiring around it, NOT involved in the HID system. The Bulbs were located OUTSIDE the headlight assembly, as not to heat up the suroundings.

The Results:

-The HID wiring compared to the surrounding wiring was only 2.5 degree F above the surrounding wiring.

-The stock 10A fuses were only 6 degrees F above the surrounding non-used fuses.

The control:

I pluged a stock halogen bulb into one side, and repeated the test

The results:

-The Wiring connected to the Halogen bulb was TEN degrees warmer than that of the surrounding wiring.

-The stock 10A fuses were THIRTY degrees warmer than that of the surrounding unused fuses


Conclusion: the stock wiring system in the Viper is very good. Independantly fused, relay controlled, with adequate gauge of wire used. It is more than sufficent to sustain powering of HID systems by itself, without any additional harnesses. The factory Halogen 55W bulbs are a larger load than the HID system.

Side Notes:

-Tests done with HELLA 35W Internal Ignitor Ballasts, the industry standard.

-Polarity of harness MUST be switched on the bulb connector before plug and
play.

-One thing you have to watch out for is not turning on your HID's while your battery voltage is under 10V. When the ignitor activates to start the arc, there is a bigger current draw- at low voltages, this is exaggerated. LOL, at $4 a pop in fuses every time you do this, you will soon learn not to do it! One other thing I suspect is that the same MAY occur during engine cranking if your battery is weak. (This is the reason factory HIDs are shut off by the body computer during cranking, and when the battery starts to go dead) Halogens dont have this problem because they just "dim out"... HID's cant. The arc ceases. When the arc shuts off, the ballast will try to ignite it again and again- pop goes the fuse(s).

-The arc is VERY similar to Arc Welding, is JUST as bright, and the same color. It was blinding my camera as you can see below. (it is VERY cool to look at a bulb with a welding helmet on, you can see the arc, and its differnt color temp layers)

Re: Quick write up on HID installation, and impressions....

Good info. I took the extra safe route and used new wiring harness/relays AS SUGGESTED by the vendor. It may take another 15-30min to do this and certainly beats chances of burning up factory wiring harness.

Re: Quick write up on HID installation, and impressions....

Update: I actually got to start my car today (YAY!!!!) come to find out, Starting the car when the battery is decent WILL NOT cause any problems with fuses blowing, as I speculated above. Only time I can get it to blow a fuse is when the battery is almost dead, and you try to ignite the lamps. If the lights are on while battery is dying, they simply shut off and dont restart, no fuses blown. (ie, all interior lights dimming, and radio no longer works)

As Suggested= I can charge you more if I sell you this too.

I think I did a pretty thorough job of proving that it isnt neccisary in our case. At the least, that gives you the option at some point to rid yourself of some messy wiring, etc.

However, your ballasts may not be as efficienct or use external ignitors, in which case would draw more current...that may be the reason in your case. I only tested Hella ballasts.

Where was the 12V power source that you tapped into for the new wiring harness? Or did you run a direct line to the battery? Just curious since I just got a 4100K Philips kit. I'm going to install it this weekend.

Re: Quick write up on HID installation, and impressions....

I work at Sylvania and the sales guys are telling me in 3 years all cars will have these.

Dan-How much did you kit cost?

Re: Quick write up on HID installation, and impressions....

DansAuto- A little over 400.

And as far as what your buddy says...after my experience with them, we can only HOPE!

Also, by chance would it be possible for me to get a set of D2S bulbs from you, so I can do a little experimentation?

Re: Quick write up on HID installation, and impressions....

hey, I'd much pay $20 more for the wiring harness than burning up factory harness. I have yet to experience any fuse blowing and my install is just as clean as your. I would highly encourage everyone to do some research before you start sticking in HID lights to factory harness. I believe CATZ hid kits was designed for direct plug in...w/o need for additional relays.

Re: Quick write up on HID installation, and impressions....

See my message above:

"I think I did a pretty thorough job of proving that it isnt neccisary in our case."

I am not arguing with you man, you can do whatever you would like with your car. I am just sharing findings from this test. The harness, IN THE CASE OF HELLA, is NOT needed.

Yes, I blew a fuse. so what? I know exactly WHY it happened, that makes all the difference. Besides that, I am still using factory Fuses- they will blow long before harness damage occurs...thats the point of them. I cannot get it to repeat in any way, now that my battery is charged. When I said my battery was dead, IT WAS DEAD...as in radio wasnt even working. If you tried the same thing with your system, it doesnt matter what gauge wire you use or where it it connected- if you had a fuse equivalent to the same amperage, it would have happened to you just the same.

Re: Quick write up on HID installation, and impressions....

dude, "I am not arguing with you" either... I just want people to make educated decisions about HID. You blew a fuse - so what??!@! are you kidding me? Properly designed setup doesn't blow fuses... sorry I am not the one selling $hit. You are. You basically lost all respect from me with your earlier post about HID system. Do you want me to dig it up??? I didn't think so. Meanwhile chew on this...

Dan:

Nice info, maybe the following can add a little insight. Hid ballasts have a high inrush characteristic that is unrelated to load current. For approximately .010 sec (when energized) they will pull currents that are 5-10 times the load current.

I do a lot of circuit sizing and in general I will use a fuse that is 2-3 times the load current on hid ballasts. A fuse has a curve called a time current curve (TCC), this is typically used to size inrush type loads. Although the inrush could be 500%, the time is so short the integrated rms value is far lower, still typically greater than 200%.

Another problem is cycle fatigue in the fuse element. When you approach 60-70% of the fuse melting curve you get metal fatigue or crystallization of the element. This increases the fuse resistance and the cycle becomes self propagating till the fuse opens. Therefore, the fuse may provide dozens or hundreds of starts, but, at some point the element dies from metal fatigue.

One more insight into fuses and circuit breakers, they are very poor overload devices and are very inaccurate when they see currents in the 100-200% range. In general no manufacturer can guarantee that a fuse or breaker will open at 125% of its rating. The smaller fuses found in cars are somewhat quicker.

If I were sizing a typical non-inductive circuit I would size the fuse at 150-200% of the load current. A reactive circuit like a the HID lamp/ballast, a minimum of 2-3 times the load current. The accurate way to size the fuse is to put a scope on the ballast circuit take a snapshot of the inrush curve, calculate the rms current and draw the inrush point on the tcc. How about this, put a list together of all the fuses in the Viper and I will make up a kit for about 10-20% of the retail cost.

Be careful when using an infrared thermometer. I have an accurate infrared and a high end digital set of thermocouples. I measure conductor/terminal heat rise in my business. There is a big difference in accuracy between the two thermometer types when measuring small surface areas. The infrared units measure the average temperature of beam area. The laser pointer on the units are not beam diameter. Beam diameter gets large fast. However, in your case definitive measurements aren't that important. The relative differences are just as good. All in all, your observations were very intersting, enough for me to consider the install myself.
