Remove the two screws. Then remove the light housing. The bulb is right there, pull it out. Cheers
The actual bulbs; yes. The headlight housings; I don't know. For bulb information, see sources and related links below.
Refer to owner's manual for pictures of how to do it but basically you just pry it off and then twist and pull light bulb off
typically, you only change the bulb (it the bulb light is out). they usually cost a few dollars, if it is a busted headlight, do not know.
It cost me less than $3 if you talking about the bulb...not sure about the cover too
Push brake light housing toward glass and pop up out of deck. Pull housing toward you and turn sideways. Twist and remove bulb. Replacing is the opposite.
