Hi guys,

I've got a 70 f100 swb 2wd and the other day my right side tail light and marker light stopped working. Everything works on the left side, and everything but the tail light and marker light are working on the rights side, i.e., blinker, brake, and reverse light. What would you suggest?

 

I suggest doing some actual troubleshooting like checking grounds, voltage, and bulb sockets, and whether both bulbs might be blown.
