To prevent hyperflashing with the new LED bulbs on your 1993 Chevy C1500, you will need to add a single Diamond LED Load-Resistor # DI34ZR (which includes two resistors) to each turn/blinker circuit on the truck. If the same circuit wire is feeding into the two bulbs on each side of the truck, you should only need one resistor on each side, in-line with the circuit before the bulb (for a total of two).

If each individual turn signal bulb is fed by it's own circuit wire though, you would need to add one for each bulb (for a total of four).

I have attached the written installation manual that you can look through as well.
