pretty easy i just used a butter knife to take the lenses off it feels like you are going to break them but you won't unless you just extra rough. You have to make sure you turn you interior lights off by turning them all the way down until they're off otherwise they will be really hot. Also since the leds fire forward you have to place them which ever way you want the light to project mostly. I found aiming the maplights against the metal reflector was better than aiming them straight down and i aimed the vanity lights slightly up so when i look in the mirror they not so blinding. But you just have to play with them to see which way works best. Here's the link where i ordered mine i found these to be really cheap http://lxaccessories.com/product_info.php?cPath=62_1&products_id=89
Yes and no..Yes because they're cool looking no because you can't see sh** with the blue ones thats why i got white vanity lights when i need to look at something but even those are too damn bright if you want to look in the mirror lol.
