Bought HID's...big issues??

So basically i bought a set of RTX hi/low HID kit. And i plugged it in and the bulb comes on flickers a couple times but comes on, but as soon as you fire up the truck it goes out. The hi beam works fine either way jsut the low beam is being dumb. So we tried a relay inline with the system and it jsut pulsated the HID. This is the biggest puzzle to us as to how it works when the truck is off but when on the ballast woulnt turn on??


So basically wondering if anyone has any answers to all this madness....tomorrow we are going to try and put a capacitor inline with the stock low beam wire as i have seen on other sites people doing...

Its jsut ahrd cause you read so much crap and then noone ever shows what they did or gives a wiring diagrahm for anything, jsut like to argue their point...like they say use resistors not capacitors, or use capacitors they are fine, or i isntall many of these ktis and use resistors on all them but they never give sizes of the resistors or where they go inline with? So i found a site of a guy with a charger not same car but tis a chrysler and same bulb and he used a capacitor inline for his car and gave the size and all so thats why i am trying this guys method until soemone else can tell me different???


So wondering if anyone else had or has these issues with there HID's??

And what the solution is to it down to details, because i had one kit before it was a single bulb kit and just had a ballast no little box inline with the bulbs after the ballast, and it was direct solder power into 12 volt and neg to negative on harness and this kit woulnt work near the same.

So any help is very appreciated!!!

thanks,
Jordan

your truck has a computer which controls your low beam, the HID ballast doesn't have enough resistance and the truck thinks the bulb is burnd out. the flickering is caused by computer sending a voltage to check the system.
only low beam circut is set up like that, that's y hi beam works fine.
heres how to fix it. measure the resistance of the original halogen bulb, measure resistance of the ballast, the difrence between the two has to be compensated by a resistor in line with the ballast. so if your bulb is 30ohm and ballast is 10ohm you will need to instal a 20ohm resistor on your power wire to the ballast.
hope that solves your problem. thats what I had to do with mine. Good luck

IF you have to much resitance is it a big deal because i thought you typed 200 ohm resistor so i got a 330 ohm resistor from work today thinking a little more would be good and no i see you typed 20 ohm resistor :S so hopefully it woulnt be a problem?

A resistor higher than needed wouldn't be a problem since it will act more like a no-resistor at all, i.e. flickering will stay. Problem is to put a lower resistor, which could represent a higher load to the circuit (i.e. higher current).
A thing to consider is the wattage of that resistor. I've read elsewhere it should be a 25 - 30 W. If you install a small power one, it will surely burn off.

Be careful measuring the resistance of the bulb since they vary a lot with temperature. I mean you can measure 8 ohm or less with a meter that injects only a mere milliamps in it... and that ohm value has nothing to do with that at 1000 F operating temperature when the circuit boosts 4 or 5 amps through it.

Guys stepping into this conversation I may well be in over my head as I'm far from an electronics genius.. But I believe that the resistor your persuing is a 25W 24 ohm power resistor..A metal cased finned to cool type that can be safely mounted/screwed to another metal surface to help cool / disapate heat off the resistor itself. ... This type resistor may be very hard to locate.. If you have trouble locating one PM me and maybe I can steer you to a source ..Just my $0.02 worth

So I had a resistor and it didnt work soooo.... i tricked the module another way, the only thing is when i click my high beams both the low and high are on but no biggy woulnt use my highs that much anyways if ever.....

SO anyways, the system needs to basically see power at the low beam end of the harness so i plugged the HID harness into my stock one, then i spliced a wire from the acc power on my side marker harness to the power wire for the HIDs....

this being it sends a 12 volt signal to the HID ballast to turn it on when i turn the lights on, and then the truck reads a voltage thinking there is a bulb..... lights work fine, and work of the same bulb that comes on when they do sooo done and done!

Now if a ballast ever burnt out it just wouldnt tell me inside the cab but i am sure if you turned them on you would know if a light was out considering how bright they are!

SO anyways to wrap it all up thats how i did mine and everything works besides like i said you click for highs and the HID low beam doesnt go out it stays on with the little high beam light making it super bright almost a benefit if you really need high light haha!

Now i jsut got to adjust my driver side light to point down more with the other one also helping form going into cars haha

Thanks for all the help guys!
