Fender top mount turn signals

I gottem, but they don't work. :( I don't know why either, I have the lights hooked up to the blinkers, the blinkers work, I have brand new bulbs, but neither of them light up when I put my signal on.
Could be an issue with your turn signal switch. The fender mounted signals take a special switch as the fender mount lights run through the switch. Mine don't work on my 74 Valiant...and I suspect the switch has failed. Replacement switch on Ebay is $86 bucks. A standard switch is usually about $26 bucks....
