xenon fog lights !!

no-way · 08-31-2007

hi today i installed a fog light xenon ( bosch hid )

but i have aproblem that its make flashing !!
and i tryed in defrent ways to make it alway's on but i failed

in the end i maked it olike this way :-

* on the (0) all lights off
* on auto the fog xenon and the hid lights are on
* on th seconde mode with out pulling the switch the fog is on and when u pull the buton its still on with out hid lights is on

* on the third way all lights are on
* on parking way when i turned the car off and make the left or right light on the fog still on together

and i have inside amalfunctions error for right and left fog !!
so what should i do

Sounds like you need resistors for the HID fog lamps.

yuppers, NR4l Has a whole write up about it, just search it.

thanx alot friend

I got a whole new write up regarding HID upgrades, parts and all. Also a small document regarding resistors and LEDS. Problem is they are converted to pdfs but are over the allowed limit for posting on the forum. So i am trying to work that issue out.

And admins advice is welcome... i have already compressed them as much as i could.

no regret Post it!!!! benfit the masses!

wish i could my friend. But this forum limits you at 512kb for pdf uploads.

I may just have to post it on the other forums and link it here...

no-way, how did you wire up the HID foglights?

I'm guessing that you connected them direct to the battery, and used a relay triggered by the original fog lights wire? Reason why I guess this is because looking at your ballast, its one of the high power ones(50w as opposed to 35w for standard HIDs), and if you connected the ballasts directly to the fog lights wire, you won't be getting the bulb out warning OR the flashing. This is because the stock halogen bulbs are drawing 55w, and if your HIDs are drawing 50w, that difference won't be enough to trigger the bulb out warnings/flashing. In fact, 35w is probably enough to not cause it, speaking from personal experience, when I swapped my halogen H7s from my low beams to HIDs, I connected it straight(NOT using relays) to the existing headlight wire, and it worked fine without needing any settings to be changed on the gateway/SDS/etc to tell it to expect less current, and I didn't get warnings/strobing

If you did use the relays(and direct connection to battery) to connect the fog lights, then this is what is happening:
1. When youn turn your fog lights on using the switch, the power is flowing from the SAM to the fog light wire
2. The power in the fog light wire triggers the relay, which then sends power from the battery direct to the HID fog light
3. Unfortunately, if all the fog light wire is doing is to trigger the relay, then its not drawing enough power, which flags to the SLK computer, that a bulb must be out, which is why it triggers the warning message. Along with the warning message, it starts strobing the power to the fog light wire, which in turn strobes the relay switch, which in turn strobes your HIDs = not good.

If what you want is for the fog lights to always be on when the car's running, then I think you should probably wire the HID foglights direct to the original fog light wire, which will solve your warnings/flashing, then add an auxiliary power connection to the HID foglights so you basically have 2 power sources to the HID foglights(1. from original fog light wire, 2. from auxiliary power source/trigger). Noregret might be able to help you more with this, he's the electronics guru.

I'm thinking of doing something similar where I want my foglights(standard stock halogen) to be on whenever my headlights are on, so my plan is to leave the fog lights connected as stock, then add a relay(triggered from the headlights) to also supply power direct from battery whenever the headlights are on.

my fog light won't turn on when there is a lot of fog... why is this?

fog lights are manual activation only.
