LED bulbs not lighting up?

We have all been there, we purchase bulbs from online sellers, and once we get them in we are full of joy and excitement and ready to install. 

Some of us have installed some bulbs and find out that they don’t turn on, so we start assuming that they are defective and start having a huge disappointment.

Now before you go and complain to the seller or give negative feedbacks, here are a couple of ways to troubleshoot your “defective” bulb.

 STEP ONE: Rotate the bulb 180 degrees.

This step is the simplest way to figure out if your bulb is defective or not. You simply just rotate the bulb 180 degrees to see if the bulb will light up.

Now you may ask why it is necessary to do this, well most LED bulbs are polarity sensitive, which means they will only work when the positive pin matches

up with the positive side of the socket/plug you are putting the bulb into.
