Hey everyone welcome to the channel!
What kind of lights do you use for night riding?
We've been using Lezyne lights for the last few years and they've been very good.
Just like many others if you press on that power button
they're gonna give you a status of the battery charge.
But recently I came across a couple that actually don't give me any LED indicator anymore.
Are these broken? Can we fix them? Let's take a closer look!
Again the symptom is no status LED.
You can see the working light gives me the green, orange, or red, this one gives me nothing.
My first thought is battery discharged so I connected it to a power brick
and what you're gonna get is this blinky blinky light which is normal for all these lights, that's usually good.
However if I disconnect the charging cable and I press the LED I still get nothing.
So time to open this up!
First we're going to remove the handlebar strap,
this is all rubber so it stretches out
and that reveals your 4 mm bolt that is for the whole rubber band.
Put that aside and that's gonna reveal this tiny tiny bolt.
To open it up you're gonna need what's called a T7 Torx.
The alternative can be one of these tiny precision flat screwdrivers.
This bolt is not too tight so it should be easy to remove.
The Power and Mode button is actually covered by this rubber piece
just pull it out, some models might have a plastic post in here, not the case with this.
Next you're going to slide the insides out starting at the lens end
It's just gonna slide out just like that
You can see the seal here around the lens and unclip it and just put it aside.
Depending on the model again you might be able to remove the battery at this point.
In my case I can't, this is a LEZYNE Macro Drive
I believe the Power model is the same as this,
so what we need to do is
grab that 4 mm bolt/ strap, remember the handlebar mount
just thread it
pull up on it and push forward
and as you do that the whole electronics slide out
and that includes the battery, battery that is attached to the motherboard.
Just pull gently on the cable
and disconnect the battery.
When handling electronic circuits components can be damaged by what's called ESD
so what I would recommend is just to touch the ends of it don't touch the components on the board.
I have removed the battery and I actually measured this and this is the problem with my light.
This shows nothing, zero volts.
Battery details are 3.7 volts 2800 mA,
the diameter of this is 18.5 mm
and the length of it is 68.5 mm.
I was lucky to find this replacement battery online.
Reconnect the battery, here we go,
and if I press on that tiny button which is here
the little LED comes on telling me that the battery is fully charged.
So here we go, that was my problem, the battery was dead
so next I am going to turn this OFF and let's reassemble it!
Reassembly should be easy because we have a lot of experience now, first of all
this rubber plug for the USB port should be installed because it goes right underneath the motherboard.
Plastic mount has a groove here on the side
so as you slide it back at some point you're gonna have to turn it around
and remember we had to lift this up a little bit? Here we go
so continue to slide it in
and just squeeze that battery cable in so you don't pinch it.
Next we're going to reattach the lens this slides in from the battery end
and then it's going to clip up top.
And finally we're going to push everything back into the housing.
You have two ends to this housing one that is flat that's what you're going to start with so line them up
and it's just going to slide right in.
That tiny bolt that we've removed initially goes right back in here.
It does have a little o-ring on it just to keep this sealed.
I'm gonna tighten this all the way to snug, no more.
And you're gonna have to reinstall that button cover remember this is made out of that transparent rubber
it allows you to see the indicator, here we go.
And finally you're ready to reinstall that handlebar strap,
the 4 mm,
and I don't always remember how this goes, I think is backwards like this.
Depending on your handlebar you may or may not use this extra piece of rubber
Turn it on for one last test and the light is ready to go!
Or at least that's how you replace the battery and troubleshoot the issues with a LEZYNE light.
What do you guys think? Did you find this useful?

Do you right at night?
We absolutely love it, if you have never tried it I highly recommend it
and until next time hope to see you on the trails.
Cheers guys, cheers!
