Hey Guys, I just installed HID lights in my
truck....Holy Cow they are sooo cool.
Just wondering if anybody else did and if so,
did you have to adjust them down? They look
a little high. I also lost my highbeams.
Any responces would be cool.
Have a Good One.

Hi,
What did you buy?
I ordered SHOWOFF "PURPLE" HID XENON HEADLIGHTS # 9007
They are supposed to have low/high beams. I hope to get them in a couple of days...

 

If even the highbeams on those new bulbs exceeds 65W, yank those bastards out.

Jackal,
Could you please explain why? Any reasonable reason??

I installed mine yesterday and actually I don't see that they are brighter than stock. I do a lot of driving during nights so I really want to have more output without bothering people though... but the look is cool...
And high beam on one of the bulb does not work, have to exchange...

 

I had 60 / 80's that was supposed to look like 80 / 100's and they fried my harnesses AND ground. I replaced my harnesses and got some stock wattage Eurolites and they are actually brighter.

98Silverf150, I believe that Jackel & AB don't realize that your are talking about HID (High Intesity Discharge) Lights as made Sylvania and marketed as Zenarc.

They seem to be refering to the simple 9007 replacement / upgrade bulbs that many put in their OEM headlight assy. For others without HID lights, they have a point as the higher wattage bulbs can cause wiring harness failures.

As for you and your HID's, if they are the Zenarc units at least, they are adjusted (aimed) the same as the OEM units are, buy rotating the adjustment screws (must remove units to access) on the back of the assy. Also, I think the Zenarc uses HID for low beam only and uses a separate bulb for the high beam. If I am right about that, you may check your info that came with the kit to confirm, the high beam bulbs may have not been connected correctly.

 

Petrol, are you not using "the simple 9007 replacement / upgrade bulbs that many put in their OEM headlight assy."? How much did you pay for the HID setup 98? How do you like them?

While I can't speak for 98Silverf150, I can say that the HID lights are really like night and day compared to the OEM headlights. They are also very easy to install. The only 'problem' I have with them is that I can't afford them . I have seen them for as 'little' as $700, but that's still a bit much for me right now.

 

I've read that true HID systems don't have high and low beams, just two options......on or off.

 

That would be incorrect. . . though some of the newer 'high-end' systems as found on the new bmw 740i, merc s500, infinity Q45, etc. have HID for both hi & low beams, many of the 'lesser' systems rely on conventional Xenon/Halogen gas filled 'bulbs' for the high beams (with some systems the HID 'low beams' remain 'on' when you switch the high beams on for a combined illumination).

See, the ture advantage to HID lighting systems is NOT just the brightness & whiteness of the light, but also the 'sharp' cut-off or control of the light so as to not 'blind' on-coming drivers. This is not typically a factor with high beams as you 'want' to scatter the light a little more up the road as well as to the sides.

Anyway, I just noticed that this post is 'inappropreatily' in the 'engines' forum and should be moved so more folks who know about HID systems can 'chime' in.

 

I am a dealer for the Sylvania HID's. They do have a halogen for the high beam and the HID for the low beam. The headlamps do have short warm up time of about 30 seconds which is really quick compared to other commercial type hid lamps which can be several minutes. Sylvania also offers a low beam fog type lamp that will mount to a bumper, light bar, etc that does a pretty good job. It does have a higher kelvin temperature than the f150 pods.

One of the reasons that the higher (cooler) kelvin temp on the hids help is because you eyes are more sensitive to that portion of the spectrum. Studies have shown that you periprial vision is better with the higher kelvin temp lights and the shift is to design roadway lights with metal halide (white light) instead of the much more "orange" light of an HPS (high pressure sodium). Basically a typically incandescent light is around 2700 kelvin, a halogen is around 3200 K, metal halide can be anywhere from 3000 (with a special coating) to as high as 10,000 kelvin. The higher the number the "cooler" the light.
