Lexus RX 300 HID Kit HID Headlight Installation
|
The following Lexus RX 300 HID install was
done on a vehicle owned by S.T. of Michigan.
The 2002 Lexus RX 300 was not equipped with
factory HID Headlights, so our 9006 HID Kit was
used to install the upgrade that this vehicle
missed at the factory. If your RX 300 already
has factory installed HID Headlights, then you
can upgrade the look of your vehicle with our
HID bulbs for vehicles with factory HID.
The first step is to check access to the area. On this
RX 300 (1999 - 2003), there is good access to the
driver side bulb, and modest access to the
passenger side bulb. The low beam bulbs are the
outer set of bulbs, and the high beams are the inner
set of bulbs. Be sure to identify the proper set of
bulbs before starting.
Remove the driver side low beam bulb (9006
Halogen) with a quarter-turn to unlock it, then pull
straight out. Once the bulb is out, remove the stock
bulb from the factory harness. The factory harness
on this vehicle is the brown plug at middle left
above.
Always insert the HID bulbs as soon as you
remove them from the protective packaging so
that the bulb will not be exposed to contaminants
or physical damage.
Just as the stock bulb was removed, insert the HID
bulb and lock it into place with a quarter-turn in the
opposite direction used to remove the stock bulb.
Plug the factory harness into the HID bulb plug
(blue). There should be two plugs from the HID
bulb that are loose and still need to be plugged in.
Plug the two remaining wires, into the
corresponding plugs that are on the ballast. The
plugs will only fit the correct corresponding wire.
When the wires have all been plugged in on one
side, remove all tools. Close the hood, turn on
the engine, and check to see that the new HID
light is working on that side.
On some vehicles the HID side may not turn on.
If so, check the wires to be sure they are
securely plugged in.
If the wires are all securely plugged in, and there
is still no power, you may have to adjust the
polarity on the ballast by turning the ballast
power plug around. We don't know why this is
the case but that's the way it is.
In the photo at right, installation of the passenger side ballast
is shown. Access to the area was not as good as the driver
side, so we removed the bolt that secures the windshield
washer fluid tub, in order to gain access to the area. Once the
old bulb was switched out with the HID bulb, we used the
same bolt to secure the ballast with the kit-supplied bracket.
In the photo below, the ballast plug needed to be turned around to reverse the polarity. If there appears to be no power to the lights when you
test them, you may need to do the same with your installation. Note in the photo, how the metal slip stub is exposed.
