Are you sure the bulbs are burned out? Really sure?? (This is just a chance for you to play with your new Fluke). Set the Fluke on the ohms setting, and touch the leads to the base contact, and the side contact on the bulb. If it reads close to 0, the bulb is good. If it reads "OL", which stands for open lead, the bulb is bad. Works on fuses too. Enjoy! ::
