Have CD LEDs on front and rear. I only had to use the Inserts, no programmer or extra electronics. I did have to remove the outer ring as they were much to big. The outer ring came off super easy, had to scrape off some of the rubber / adhesive for the perfect flush fit though. This was for my 2013 BreakOut. I got the front ones right on the first try, right part, everything worked. I ordered the Rear and got the wrong part number (my fault). CD only offeres I think 70% $ return so be careful.
The front are amazing and both white and amber are significant improvement over the stock bulb.
The rear are great also considering those 2 billets serve as running, break and turn signal. They are always red but very bright. There is also a flasher unit you can get that make the break lights oscillate. Also, there is a light bar that goes under the fender to replace the reflector but I have not tried that. I can dig out the PArt numbers if anyone wants specifics for my model.
