(Do not pay attention to negative reviews. As long as you know what your vehicle is compatible with, it is nearly impossible to screw this up. There is no splicing so people who leave bad reviews for this, either bought the wrong part or simply did not know what they were doing.)After going through a few different avenues via Amazon and eBay, I circled back to these, despite the rating and reviews. BEST THING I could've done. First off, this was the only 7444NA with Prime shipping available. (Had to pay for Same Day ..) but it was worth it. Plug and play forsure! Had a polarity issue so just 180'd the connector and vuala! Took under 5 minutes for complete installation. I didn't even have to drill into my chassis. Just zip tie the resistors on both ends of the wires like a piece of candy. Make sure they are flat, parallel and not touching each other and plastic/other wires. They do get hot, fast - as they should. A tip for those who may not know: DO NOT BUY DECODERS if you plan to use them for SWITCHBACKS. This review has been specific to my 2017 Honda Accord Sport SE for installation of switchback LEDs.
