Was at NAPA yesterday to pick up the 1683 turn signal/flasher rear taillight bulb. Was going to get a couple of spare 1251's but the store only sells them in unopened boxes of 10. $30.00 + tax. I'll order a few online I guess, just to have as spares. I really don't need 10 laying around. Used di-electric grease on bulbs and sockets before reinstalling them. Will get around to doing the same on other side.
