SignUp Now!The thing is, some cars will work without using relays, but MOST wont. The wiring in our GN is aging in a big way, and picking up resistance along the way. The "startup" demand for the HID ballasts puts us in the relay-needed category. Otherwise, the HID's use less current than the standard halogen bulbs. It's that startup that gets you. Low battery, high surge, and the bulbs just flicker instead of coming on.
The startup on a typical ballast lasts around 50-200 milliseconds, just enough for the power sag to prevent the lamps from striking the arc. Now, if the bulb doesn't start, there is an internal spark gap in the ballast that absorbs the high voltage energy (at least there is in the Philips boxes). Problem is, the spark gap doesn't last very long, eventually allowing the high energy to self-destruct the low voltage internal components. Then you have a melt-down. So, strong voltage at startup is absolutely necessary.
If you ever see your headlights start to flicker, it's telling you that you need relays. But usually by then it's too late.
I bought a pair of 10K HID s off ebay that were very reseaonable
Hi Bruce,
I'll check with Jack. Looks like the picture quality got downsized a bit too much
I have the original at home. I'll re-create the PDF in a higher resolution.

Alradco, What are you doing to seal the back of the housings? I know these kits are all vented behind the HID bulb, do they need to be vented? I'm hearing a lot of people are having a lot of problems with moisture buildup inside the housing.
Bruce Urie said:Please tell me how you're going to seal them...I'd like to know......wouldn't the heat from those bulbs melt your sealer? Just curious.
