Last month, our customer Jesus purchased a pair of 9006 bulbs for the low forward lighting on his 1999 Jeep Grand Cherokee Laredo 4.0.
Several days later, he came back and told us the bulbs were perfect condition but didn’t work, he was quite upset as he already paid the mechanic to install them, so he thought the lights were defective and demanded a refund.
We have heard of this issue since we started our business on LED bulbs, the lights are not defective. It is because the positive and negative prongs are opposite to what the car prongs are, all you need to do is reverse the polarity and the bulbs will light up.
This customer followed our instruction to reverse the polarity, and the problem solved, he also left good feedback for us.
So if the same thing happens on your LED bulbs, please reverse the polarity to make the bulbs work.
Mine were working fine. Then off all of a sudden. Just the fans turns on and no light. $99 pair of fogs light that work for a month and then are defective
Mine wont light up , flipped them twice on my 2023 f150
Hello! I love the product and the community behind lasfit, just installed my first set and the prongs needed flipped to change polarity so reading this made me giggle cuz before I noticed the +- I thought they were ineffective bulbs as well… would love to partner up and possibly help advertise to everyone I know to purchase your bulbs is there any “sponsorship deals” you guys offer?

I bought the switchback t-series for my Chevy Colorado and the amber lights work fine but the daytime running lights aren’t working at all and it’s the opposite when I switch the bulbs 180 degrees
