Very easy install and happy with the results, but have a few of comments.
1. Once you break the seal on the promoter apply to both sides immediately. I installed one side then went to do the other and the promoter was dried out and couldn't use on the second side.
2. The instructions tell how to fix hyper flash but it did not work on my 2018 F3L.
3. The customer accessory power under left service panel is only hot when the motor is running. So the use of the hazard flashers does not use the new lights when the motor is off, such as when parked on side of road with motor off. Not sure how this could be done different, but wold be nice.
