You rotate the clear or frosted lens cover and it pops off - counter-clockwise for removal. The bulb will be exposed - it should pull straight down or in some cases they are horizontally installed. You will know which when it's exposed. Careful, if they were on soon before then they will be HOT.
That's how it is on my CCD.
EDIT - I see you said LED - mine are halogen but the ones I've seen remove the same.
