How do you replace a tail light bulb on a volkswagen beetle?

I located this amswer at http://www.myvwlemon.com/ubb/Forum3/HTML/000245.html IF YOU NEED TO REPLACE YOUR TAIL LIGHT BULB, FIRST REMOVE THE COVER(ITS ROUND) FROM THE INSIDE OF YOUR TRUNK, THERE WILL BE A BLACK KNOB THAT NEEDS TO BE UNSCREWEWED TOTALLY TO RELEASE THE BACK LIGHT CASING. NEXT, ALONG THE REAR FENDERS WHERE THE LIGHTS ARE, THERE ARE TWO GAPS. THE INSDE GAP( NEAREST HATCH BACK DOOR) IS A RELEASE TAB/CLIP ON THE LIGHT INSIDE BETWEEN THE GAPS. INSERT A BUTTER KNIFE OR SOMETHING SLIM AND PULL OUT CASING(DON'T BE AFRAID, AND IT TAKES A LITTLE FORCE TO PULL OUT). AFTER YOU PULL OUT CASING,YOU'LL FIND TO LIGHT SWITHCES(ONE IS FOR THE TURN SIGNALS AND OTHER IS YOUR BREAK LIGHTS). TURN THE LIGHT SWITCH COUNTER CLOCKWISE(ASSUMING IT'S HANGING UPSIDE DOWN)AND REMOVE. SWITCH OUT LIGHT BULB WITH NEW ONE(AUTOZONE HAS THEM FOR ABOUT $4.00 - PACKAGE OF 2)REPLACE EVERY THING BACK AS YOU UNINSTALLED IT. ITS RECOMMENDED TO REPLACE ALL BULBS, THAT WAY IT YOU DON'T HAVE TO DO IT AGAIN LATER WHEN THEY GO OUT. IT'LL SAVE YOU LOTS OF TIME AND MONEY. HOPE THIS WILL HELP ANYONE SO PRINT AND SAVE IN YOUR MANUAL FOR LATER USE.
