DETAILS

Dual Output Quick Fit SMART Harness™ | Our all-in-one wiring loom

Our all-new Plug & Play SMART Harness™ for Quick Fit installation of your driving lights. Incredible High Current 10AWG cable, negative switch compatible, waterproof switch & DTP to DT Reducers bridging the compatibility between the two connector types. Our SMART Harness™ has been designed around the consumer to simplify the installation process.

The supplied HB3 and H4 Adapters trigger your driving lights from your high beam without cutting or soldering any wiring. Simply unplug your HB3 or H4 connector at the back of your headlight's bulb, plug in our adapter, and you're done! Driving lights will only trigger from a high beam, and the switch will act solely as an isolator.

Our new SMART Harness™ has a built-in microprocessor that automatically detects whether your system is positive or negative switched, and will work right out of the box without any modification whatsoever. Toyota's, Ford Ranger, Mazda BT50 among many other popular 4x4 are notorious for being very difficult and costly to wire driving lights to high beam, our quick fit harness takes all the guesswork out of it.

It contains everything you need to get your lights connected: ON/OFF Switch, 60A Relay, 35A Fuse, ribbed cable protectors, heat shrink wrapped relay, DTP to DT Reducers.

  • Featuring a total of 4.8 meters of wiring (fully stretched out)

wasting your money
Size: 35 x 7, Color: White-rgb
I’m very disappointed with this purchase. The shelves have a questionable finish - honestly, you can get something cheaper and much better quality at IKEA. But the biggest issue is the lighting. None of the lights work. I put in brand-new batteries and absolutely nothing happens. I wouldn’t recommend wasting your money on this product.

Lights stop working after a few usage
Size: 31 x 7, Color: Black-rgb
I had these shelves for a few months now. The shelves are great and are very easy to install. I also like that they offer different sizing, so depending what you are storing on them. They can fit a lot of items and are sturdy so you don’t have to worry about it falling. The lights were amazing at first and the main reason why I bought this product, but after a few times using them they stopped working completely and no longer connect.

Incomplete kit. Missing anchors. LED are white not yellow or amber. Shelf is dented. Had to buy double sided tape for the LEDs to stick. Strips can't hold weight of charging blocks. Not easy to install

Highly recommend
Size: 35 x 7, Color: White-rgb, Size: 35 x 7, Color: White-rgb
I absolutely love the look of this coffee and beverage station. The purple LED lighting creates a modern and inviting atmosphere, while the neatly organized syrup bottles and glassware give it a professional café-style appearance. The variety of flavored syrups offers plenty of options for customized drinks, and the clean white shelving makes everything easy to access and visually appealing. The setup feels both elegant and functional, making it perfect for serving specialty coffees, lattes, and other beverages. The decorative touch on the upper shelf adds personality and style, creating a welcoming space for customers or guests. Highly recommended for anyone looking to create a premium coffee experience! ☕✨

Fabulous!
Size: 65.6ft, Size: 65.6ft
I have wanted some strip lights for soo long! I absolutely love these! Great quality! The adhesive is very strong and keeps the lights tight against the wall. Even with bumpy paint there was no issue with it sticking. The colors are fabulous, so many to choose from. Set up is very easy. Pull off the sticky tape and press where you want the lights to go. I have had no trouble with Bluetooth connecting. I run the lights through the app and it connects easily and quickly. There is such a variety of light themes to play with and set moods. This stip can be cut. I made sure to do it right down the middle of the copper lines. I recommend turning the lights off, making the cut, and then turning the lights back on again. What is cut off will not work. I had a bit extra that I cut off and the two ends overlap a little, but it's hardly noticeable if you stare real hard. These lights are so awesome! I highly recommend. Also it is so great to be able to turn up and down the brightness!
