O.K. Shame on me, and admittedly I did get confused. First and foremost I had not yet seen the reply to my original post from llebcire I ended up first purchasing the 4157NALL ($5.83 for two), but of course as soon as I got the bulb out (very easy, under the car, set a auto light on top of the ledge the front wheel fender creates)and removed in one simple reach and turn.)I did take me a minute to find out that I needed more than one hand to hold the socket and twist the bulb out, but I was able to get in to a position on the ground to extend both arms in to the space to hold and twist. I immediately saw the round base of the 1156, and panicked seeing the 2 filament flat base of the 4157 bulbs I had purchased. I went back to Advanced Auto were I purchased the 4157 and was told the 1156 bulbs had been discontinued (strange for cars that are still using them in 2009) and that I would need to go to the dealer. I didn't buy in to that and drove 2 miles down the road to Auto Zone were they had the Sylvannia 1156NALL (A- Amber, LL - Long Life) ($5.99 for two)and was pleased to slip right under the car, simple 1/4 turn to get the bulb back in the socket and simple 1/4 turn to get the socket back in to the lamp area. ANYONE can do this, please do not let the dealer rip you off by charging $12 + for one bulb and then a ridiculous 1/2 hour labor charge of $30 or more. P.S. as others have stated, apparently these bulbs burn out frequently. Learn to do this and save $$$$$. Good Luck. The Diesel
