The reverse light not working is probably a blown fuse, check in the owners handbook for the correct fuse 10 or 15 amp and the spare fuses will be in the fuse box. There will be a small fuse puller as well.If the fuse is ok check that the bulb is seated all the way into it's housing. Put the car into reverse and the ignition on and push the bulb in it should come on if it is not blown. The blown indicator light check that the correct fuse is fitted if the wrong one is in it will keep blowing. The fuse positions should be on the inside of the fuse box cover.
