I found that my old HIDs produces a bit larger output of light compared to the new LEDs I just put on. My main reason for swapping was because the hid ballast was looking disgusting with random water spots and grime and also because it rattled a bit due to the way I installed it. The LED was much more simple and like mstrjon32 said, is plug and play to original. The 2 color mode aside, I would focus on 2 key points regarding the LEDs. Lumen output and longevity which ironically are related to one another. Brighter they burn = more heat on the diode which can be a downside for 'cheaper brands'. I went with Auxbeam on amazon just because it had some sort of warranty and did not seem like a random chinese startup which mysteriously disappears when warranty comes into question. My only irritation is that I cant put the rear headlight cap on because of the LED fan taking up alot of space. You could go with higher lumen output than HIDs but be prepared to have a much shorter life span.
