Led Question


Recommended Posts

Hi all,

It's been a while since I tinkered with anything electronic, so I just thought I'd double check with some experts :p

Am I right in saying that an LED can't be wired up the wrong way? One way blocks the current/voltage, the other lets it through, minus 0.7v on the other side?

Cheers in advance!

Which means it would work in either direction without damaging it?

Whichever kind it is, I can't "blow it" by reversing the polarity?

Cree LEDs work anyway round, just make sure they fit the in the socket as I bought some but they was too big lol

It's a sealed unit with 2 wires. They are not colour coded the same as the bikes wires, so just thought I'd check. Replacement number plate lights for my bike. Fitting a tail tidy!

If you connect LED's the wrong way round they just won't work.

I'd recommend making temporary connections to check polarity first, I use mini crocodile jump cables from Maplin.

It saves crimping or soldering connections they doing the palm to forhead manoeuvre.

It was a sealed unit, so I could only see the bulb and the 2 wires coming out of the back of it. Anyway, it's done. Fitted and working first time. I'm rather proud of myself! 99% of the time if I pick up any kind of tools, there's gonna be a disaster!!

Came across another problem though....

The standard number plate won't fit, my high end exhausts are in the way. After a phone call to the manufacturer, I have to bend the exhaust brackets to make it fit. Something they forgot to mention pre purchase!!

After some digging, I found a replacement number plate that keeps the lettering and spacing the same, just cutting the excess yellow from the edges.

I don't want to attract any unnecessary attention from the boys in blue. Will the new one be ok?

What does everyone reckon? Especially you stoney. Would you pull me up on it?

An LED has an anode and a cathode, meaning a positive and negative side.

So yes, since it's DC current you can only hook it up one way, the right way :P
