These HotTails are a fantastic upgrade to my 2015 Tundra! Like many others, I've never been happy with how Toyota designated the functions for the Tundra's tail lights. I would have been happy just with the reassigning of bulb functions, but the upgraded, bright, and high quality LEDs are a bonus to be sure. Most of my driving is during the day, and I feel a lot more confident that I'll be seen by distracted drivers in bright conditions. The harnesses provided by Hotshot were easy plug and play. The worst part of the installation was (a) trying to pull the lights out without breaking the plastic tabs (partially successful), and (b) trying to get the bottom bulbs in. As others have suggested on Tundra forums, I used a tiny bit of grease on the screw heads so they would slide a bit better into position (still took some muscle, but better that than a loose fit).
Colton was awesome to deal with, and made it as painless financially as possible to ship to Canada. HotTails aren't cheap, but the quality is second to none, the functionality is a huge improvement, and I get to retain OEM looks at a lower price point than the cost of aftermarket tails (and (I've never met aftermarket tail lights I've liked). Thanks Colton and Hotshot!
