    Hi all

    Wondering if anyone has successfully replaced the 9007 bulbs with LED's.

    I tried a basic set but got no high beams.

    Any help appreciated

    There is not any replacement LED bulbs that are suitable for the KJs
    The light housing were never designed to run LEDs, it will just scatter light everywhere

    Thanks for your reply. I was wondering about hi beam switching with led's

    I know what you were wondering about, BUT the fact remains you should not run LEDs in the KJs period, well unless you do not care you are blinding every other driver coming at you

    Trying to understand.
    Would you be able to explain your position in design or engineering terms.

    My thoughts
    A light source of any kind placed in a reflector should be handled the same by that reflector as long as the source emits the light in the same plane.

    Most LED’s do a very bad job of emitting light on the same plane/spatial position as a halogen bulb. This the reason for the scatter and blinding other drivers. Even a high quality bulb that was not installed at the right angle will have this effect.

    For the same reason, HID bulbs should not be installed in reflector housings.

    To put it simply, just look at various cars/trucks etc, each reflector is designed for the particular light that is going to be run in it, be it LED, Halogen, etc
    Some are designed as reflector, some projector, we have a reflector type in the KJs and hence that is why they work best with a halogen bulb since an LED etc must use a projector housing

    While the diodes are in the approximate place in both types of bulb, they are not identical to the halogen bulb filament. The reflector is based on precise filament size and position, and having an omni-directional light source. The small changes to size and position will have significant consequences on beam pattern, this is why HIDs do not work in a halogen reflector. But more importantly, LEDs produce directional light fired at the sides of the reflector and will not illuminate the reflector surface uniformly like a halogen bulb resulting in performance loss and a lot of scattered light which is why they blind oncoming traffic. The upper rear portion of the reflector responsible for distance projection is very poorly illuminated by the LED design, which also results in loss of distance illumination.
    Many " think " LEDs are brighter, BUT, loss of beam control introducing massive glare makes the LEDs look brighter and causes people to see this as an 'upgrade' when in fact it is a downgrade really in terms of lighting.

    good reading, well anything from Daniel Stern is good

    Thanks for the info. Will read thr article later.

    What would be the best replacement for whiter light and some added distance?

    Phillips Extreme Power is what a lot recommend on various forums over all the others
    I have them in the 03 and 04 and have done great
    Just found a new set of them while going through inventory for some parts to sell off.
    Didn't even have them on my list, and don't know when I bought them but will be going in the 05 this afternoon! LOL

    Thanks for all the great info
