I'm using this Auxito 1157 red bulb to make an awesome LED tail light conversion that anyone
can do to almost any car that takes the 1157 or P21/5W tail light bulbs and just for you
I've negotiated a viewer discount for anyone who buys these bulbs direct from Auxito's website.
I'll come on to that. Full disclosure; for previous videos I bought all my own LED bulbs,
but this time Auxito have provided me with these. Hence the notification you see in the top left of
the screen. The payment being a pair of free bulbs. I'll also go through the advantage of
LED bulbs but right now let's get to fitting and demonstration. Remove your light unit and
bulb holder, making sure you know which is the tail & brake light bulb. Push in, turn slightly
anti-clockwise and pull out but note which way round the pips go on the bulb and then simply fit
the LED bulb back in the reverse way to the way that the standard bulb came out. The orientation
of the pips; because they're offset ensures that you can't fit the bulb the wrong way about. So
don't force it because you might break something. Depending on what model of car you've got,
you might have red lenses or like these Citroen C1 tail lights you might have clear lenses but a red
shield that makes an ordinary white bulb shine red in which case you can remove these red shields.
They simply unclip out, for which you'll need a small screwdriver and hey presto now you've
got a completely clear and silver rear light. So straight away you can see one advantage of
LED bulbs: you can turn the rear light from having a sort of bloodshot fried egg look to
what the Saab community on the Saab 9-3 call ‘ice blocks’: clear lens with silvered background.
If you look very closely, you can just about see the red LEDs which are very small, only a couple
of millimeters across deep inside the light unit but from a distance they look great. All that's
left to do is refit your lights or bulb holders to the car. We've now got LED tail and brake lights.
In a previous video I showed you how to convert this third brake light into LED.
Really no more effort than just changing a bulb I've now got a full suite of tail and brake lights
and in my opinion having got rid of the red lens inside the light I think these lights look a lot
better. In another video I'll fit an LED bulb into the fog light and get rid of the bloodshot fried
egg look and I've also found another dual LED product that has a mixture of amber and white
LEDs that we can fit to the indicators so that we get LED indicators with auxiliary
reverse lights which also gets rid of the yellow fried egg look. So what is the advantage of LED
bulbs over filament bulbs? LED bulbs consume a lot less power, so if you've got a full suite of LED
bulbs around your car means a little more economy from your engine which is the main reason why
a lot of new cars now, the bulbs are going LED: it really does make a difference. LED bulbs also
run much cooler than filament bulbs. For the simple reason they consume less power they
don't get so hot. That's a big advantage on this C1 or on a Peugeot 107 because these red filters
that fit round the bulb get hot from the heat of the bulb and you can actually see on both of these
(more on one than on the other) that the heat has affected the plastic: burnt the plastic and
in fact we've ended up with a hole in this red shield which means that the tail and brake light
actually starts to show white to the rear of the vehicle rather than red because white light is
escaping instead of being coloured red. Ultimately when the damage starts to get to about this level
becomes an MoT failure. That actually leads us straight into another advantage:
you get massively improved colour definition from LED bulbs than you do from filament bulbs.
I think you'll agree that the filament bulbs in the standard fitment look quite feeble, rather
orange to be honest, whereas these LED bulbs look really rich red. The LED bulbs are a little bit
brighter which in the case of tail light and brake bulbs means that they're easier to see, attract
more attention from drivers behind and hopefully will reduce the risk of being run into the back
of …. being run into the back of? … reduce the risk of having somebody run into the back of you.
There's also no colour degradation over the lifetime of the bulb,
unlike this, and they're instant on and off which is a huge advantage when you have LED indicators.
I mentioned in the introduction that I've negotiated a viewer discount for you on
Auxito LED bulbs. If you click ‘see more’ below the video and look in the description,
there's instructions down there on how to get that discount. 15% you'll get. Full disclosure,
I get a small affiliate commission as well, so if you buy your bulbs from the Auxito site
that's also a great way to support the channel. If you've got value from this video,
please consider supporting the channel and I shall see you next time.
