Hey everyone. I bought an 84 short box for hunting and have just finished the bed. I bought LED's to use for the tail lights. I have the running and signal lights working but as soon as I hook up brakes the light turns on. It was all working just fine with regular bulbs but now with LED they dont work. No fuses are blown so I dont know what to check next. When I put regular bulbs back onto the system I get the same result.

thank you!
