Many of the negative reviews I read mentioned the adhesive strip not sticking well, and it doesn’t. That’s not a bug, it’s a feature. The adhesive acts as a second hand for the installer. The adhesive helps to hold long enough to guide and clip the lights. Grant it I have only installed these two weeks ago so longevity may affect my review later and I will update my review as time goes on. But these lights are a much higher quality than what I actually expected for the price. They are brilliant, they are bright, and they were pretty easy to install. I recommend tapping one of your rear taillights for power, as you presumably will have Bly be using them when you headlights are already on. Be sure not to accidentally tap the reverse light in the fixture because you won’t have power unless you are in reverse. No matter how you tap or where you tap for power, you will need either a multi meter (which are expensive) or just get a cheap hot wire indicating tool, I got mine at an auto parts store for $9. The self tapping metal screws make installing pretty simple but don’t over tighten because the clamps are soft like silicone which is also on purpose. I gave this a 5 star because price for quality great. I’m just waiting to see how long they last to report back here. I hope this helps the reader of this review.
