I tried several off of Amazon and Ebay (9 different brands (although many are the same repackaged junk)...I was not satisfied with any of them. Then I found Diode Dynamics and ordered a 6" and 3" strip and WOW they are insanely bright. This is the set you can wire to dim with headlights on...like OEM style.

I also ordered some of the Oznium switchback bullet lights and they are very bright as well.

I have not installed / ran either light above therefore enter at your own risk. I plan to try the Diode Dynamics strips first...on the plus side if there is an issue down the road I will be able to repair myself, potentially, avoiding a long delay.
