I added two additional turn signals to the front of my truck. They continually blow the fuse. I have wired the lights directly into the blinkers with no other power supply etc. Is there some way I can wire the lights so they won't keep blowing fuses?

relays , run the power straight to the relay then to the light , then the other circut to the signal , and fuse the wire from power to the light as well of course

Your right, that's the only way.
The switches and everything else will last longer Too.
