I cannot advise you on what LED manufacturer/brand is 'best', as I have not evaluated several brands. What I can recommend to you, however, is that you consider the LED Supplier JDM Astar in your hunt for an LED supplier. I converted all of my exterior and interior incandescent lights to LEDs supplied by JDM Astar, and I am a very satisfied customer of their products and services.
Most important, their service, their willingness to work with you to ensure that you have the best LEDs for your specific truck and lighting preferences, is absolutely outstanding. If your truck is like my truck, you will encounter some areas where 'fit' and clearances may an issue, when converting to LEDs. JDM Astar will work with you to resolve any of these issues, even if it means taking the LEDs back and swapping them out for other LEDs that better fit the available space in the bulb housing. To me, that was very important, as I was a customer who was about to spend significant dollars to complete the full truck conversion to LEDs.
I welcome comments from others on this Forum regarding other brands or suppliers of LEDs, and I wish you the best of success in your LED conversion effort.
