[Music]
in this video we will be replacing the stock halogen headlights in this 2020 dodge challenger
with all new led bulbs from Alla Lighting the only tools needed for this installation is a 5 16
wrench this installation will replace both the high and low beam headlights which is just one
bulb on each side the headlights are here on the outside of the car we will start under the hood
on the driver's side access to the headlight is limited
so we'll be showing you how to remove the plastic shroud and air filter
the plastic shroud is held on by three retaining clips on the bottom
and two more in the sides begin by sliding your hand under this lip here
and then you can lift the cover up to pop free the retaining clips [Music] maneuver one end to
pull it free from the hood latch you can then lift it to reveal where the clips were attached
to release the two remaining clips on the side pull the plastic shroud towards the
middle of the car you can see here the two holes that hold the clips
Alla Lighting bonus tip you don't necessarily need to remove the top shroud to access the passenger
side this little holder here is a perfect place to hold the dust cover when you remove it
to remove the other side just lift the cover to release the bottom clips
then pull it towards the middle of the car to release the side clips
with the plastic shroud removed we can reach the driver side bulb through the hole in the top
however for the sake of this video we'll remove the air filter
there's just one 5 16 bolt at the top of the filter that needs to be removed
make note of how the filter rests in place at the bottom when you pull the filter up
and out you can see the foam seal that needs to fit tightly when you put it back [Music]
you can also remove the hose clamps holding the filter but it's not necessary as we can now move
the filter out of the way we can now easily access the back of the light housing remove the dust
cover by turning it counterclockwise pay close attention to the orientation of the halogen bulb
this will help you when you reinstall the led turn this bulb clockwise to unlock it and remove it
pull the wire connector off the bulb gently lift the locking tab and pull it apart
now that we have it out let's compare the new led to the old halogen bulb you can see that the led
looks different than the halogen with the external driver and fan but if we look closer the led chips
and the halogen filaments are in the same spot and both connectors are identical making for an
easy plug and play fit when the led is installed after lining up the tabs it will look like this
we'll adjust this bulb so the chips are facing out to the left and right and to avoid the wire coming
out the top use the included allen wrench to loosen the adjustment screw hold the chuck to keep
the large tab at the same seven o'clock position as the halogen bulb and turn the bulb until the
wire is down at the six o'clock position [Music] tighten the set screw and we can install the bulb
push the wire connectors together until it clicks in place
this bulb is polarity sensitive so we'll test it to make sure it works
it lights so we'll continue installing remembering how the halogen bulb looked before we removed
it the largest tab was facing out towards the driver's side when it was unlocked
this is how we will install the led line up the tabs and push the led into the housing
turn the bulb counterclockwise to lock it [Music]
when we test it again there's no warning on the dash but there's a slight flicker coming from
the led this is an easy fix we will install a mini decoder into the chain to install the
decoder simply plug one end into the power coming from the vehicle the other end into the led bulb
so when we plug it in
you can see the power from the vehicle is plugged into the decoder and then the decoder is plugged
into the led bulb when we test it it doesn't light but remember this bulb is polarity sensitive
so we will need to flip the plug going from the bulb to the decoder [Music]
once it's flipped you can see it all works now and still no error on the dash
now that we are assured it all works we'll go ahead and put this side back together
being careful not to crowd the headlight to avoid conflicting with the high and low beam switching
function pack the led driver wires and decoder into the housing there is plenty of room in the
housing on the right side of the bulb the last thing to do is replace the dust cover [Music]
line up the large tab on the outside pointed at 10 o'clock
turn the dust cover clockwise to lock it and that large tab will now be vertical [Music]
Alla Lighting bonus tip if the led bulb is too big and your vehicle's dust cover won't fit
we carry after-market dust covers with a larger dome to fit all kinds of vehicles remember that
you should measure the diameter of the housing and not the old dust cover when you're shopping for
a replacement this dust cover is one millimeter larger than the opening but we can fix that too
we recommend putting some grease in between the cap and the housing and then use a zip tie to
tighten it all down for a waterproof seal now we can compare the new led on the driver's side
to the halogen still installed on the passenger side it looks great and there's no flicker time
to replace the air filter wiggle the filter back into place and be sure the bottom of the
filter fits over the hole and fits tightly line up the hole on the top and replace the 5 16 bolt
side by side you can clearly see the color and brightness difference between the old and new
the new bulb has the same cutoff line as the old bulb meaning it's installed correctly
and won't blind oncoming drivers on the passenger side you can access the bulb
easily from the top now that the cover is removed
ALLA Lighting bonus tip another possible way if you cannot maneuver from the top would be
to remove part of the fender liner there are retaining clips on the liner that need
to be removed but you should know that these are one-time clips that need to be cut to be removed
so they would need to be replaced if you go this route but you can also reach in from behind to
access the bulb without having to remove the plastic shroud reach the dust cover and turn
it counterclockwise to unlock it and pull it out turn the bulb clockwise to unlock it turning it
from the seven o'clock position to the 10 o'clock position and pull it out again pay attention to
the orientation of the bulb and where that large tab is unplugging the wire connector
is the same but we'll use a flat tool this time to lift the locking tab and then pull it apart
we already know that a decoder is going to be needed so we will pre-install it onto the led bulb
we also know that this bulb will need to be adjusted so we adjust
the orientation of the bulbs so the wire is hanging down
installing the led is the same as the other side
line up the largest tab the same as the halogen you had just removed
in this case about the 10 o'clock position turn the bulb counterclockwise to lock it
plug the wire connector from the decoder into the power from the vehicle and test it
if there are no polarity issues go ahead and finish this side by packing the decoder
led driver and any extra wires into the housing
finish by replacing the dust cover
you can now finish putting everything back together the plastic shroud pieces fit together
start on the passenger side and slide the side tabs into place first
then push down in the area of the other tabs to lock them in place
on the driver's side do the same slide the side tabs into place
and then bend and wiggle the shroud until you get it back under the hood latch
press down on the tabs and the installation is complete
let's look at what the high and low beams look like now with all new led bulbs from ALLA Lighting
right away you can see the color and brightness difference we've taken the extra step to set up a
light meter so you can see the data for yourself on how much brighter these new bulbs will be a
measure of the halogen low beams has a color temp of 3066 degrees kelvin and a lux of 411
the halogen high beams comes back with a reading of 3222 degrees kelvin for the color temp and a
lux of 621 if we do the same measurements for the led the low beam has a color temp of 6789
degrees kelvin and a lux of 1 360. for the high beams these readings jump to 6886 degrees kelvin
and a lux of 1530 these new bulbs are truly safer smarter brighter better we are Alla Lighting
