Review on 🚦 Partsam Set of Red and Amber LED Trailer Fender Bullet 3/4" LED Clearance Marker Lights for Left and Right Sides by David Urbanski

What can I say, I was an idiot here. READ THE PRODUCT DESCRIPTION! REAR WIRE IS POWER WIRE, WHITE WIRE IS GROUND! Easy installation BUT! I connected it wrong. None of the devices worked, dammit, I was pissed off! BUT! I have no one to blame but myself. The seller did their job by providing the correct information in the product description. If you install these blocks and none of them work, CHECK YOUR WORK! Actually, this was my second purchase of this product, but the previous purchase was several years ago and I forgot how to connect the blocks properly. While some like me might think that black is always earthy, think again. When the trailer lighting plug is connected, the white wire is grounded. In household wiring, black wire = hot/power, white wire = earth/common. PAY ATTENTION! The goods came quickly, I will order again from this seller.
