The right, front turn signal failed on the old Race Rabbit. 

So, I checked the bulb. It looked good but I replaced it anyway - you never can tell. 

Well, the blinker was still not working. Time to grab the mutli-meter. After a couple of tests the source of the problem was revealed. The bulb holder was kaput!

Off to ebay! Ah, here's one outa a '82 Cabriolet. That'll do. Two weeks later it arrives. Looks good. 

Let's put it in.

Yay, problem solved!
